Why you can't just play "assignment football" against the flexbone/triple-option

The Navy blog "The Birddog" has a great post breaking down elements of Paul Johnson's flexbone offense. The videos he culls exhibit something I've tried to explain about defending Johnson's offense: you can't just play "assignment football." That term gets thrown around by announcers a lot, with the implication being that all you have to do is "assign" one guy to the dive back, one to the quarterback, and one to the pitch back. The problem is that Johnson will figure out your assignments and change his blocking schemes accordingly. For example, compare the two videos below, again, both courtesy of The Birddog.



Okay, so the safety ends up making the tackle on the pitch back, while the cornerback forced the pitch by taking on the quarterback. Johnson saw that, and on the very next play, called the same play to the other side, but with one important difference: the near slotback blocked the safety -- i.e. the guy responsible for the pitch back. So who now has the pitch back? Let's find out:



Answer: No one. That Paul Johnson, he's crafty. This is basically what happened when those Georgia Tech teams put it together last season and whupped up on teams. Indeed, his offense had a rather high degree of variance, considering that in some games against weak opponents it did little but in others, including against Miami and Georgia, the second half was defensive armageddon. I think the Miami game in particular was an example of a defense that had a plan for the flexbone going into the game, a decent one, but Johnson figured it out about halfway through and Miami lacked the ever important counter-to-his-counter. And once Johnson started messing with UM's defensive assignments, the defense got stretched out, and then plays like these happened:





(Ht Dr Saturday.) I will have more to say about Johnson's flexbone before the season begins, including some thoughts on defending it.(Preview question: how do you deal with the flexbone's triple scheme -- which can easily outflank the defense to one side of the field -- with the flexbone's immediate pre-snap threat of four-verticals? Keep in mind that adding another defender to the box tends to force you into a single-safety defense, which is precisely what four verticals is designed for. More on this later.)

But for now, savor last season's mutlifarious brilliance of option football writ BCS. The flexbone-triple:



End note: As a final bonus, it appears the good people at EA Sports have added more passing to the flexbone. In the video below, the old run and shoot "choice" route is shown. (Ht EDSBS.)



I'd like to think they got this from me, but all of us like to tout our self-importance, no?

Repost: Preview of Nick Saban's Alabama defense

[Ed. Note: This was originally posted last season as part of an Alabama - Clemson "coaching preview." I thought that now, in the doldrums before the season, the portion dedicated to Nick Saban could be reposted.]



Nick Saban: Still Billy’s Boy

Saban has been coaching defense – and coaching it quite well – for decades. But there is no question that the defining period of his coaching career was 1991-1994, when he was Bill Belichick’s defensive coordinator with the Cleveland Browns. Just knowing that tells you a great deal about Saban’s defense: he (primarily) uses the 3-4; he’s very aggressive, especially on passing downs; he wants to stop the run on first and second down; he’s not afraid to mix up schemes, coverages, blitzes, and looks of all kinds; and, most importantly, he is intense and attentive to detail, which is the hallmark of any great defensive coach.

Let's allow Saban to explain his defensive philosophy in his own words. From one of his LSU defensive playbooks:

“[Our] philosophy on first and second down is to stop the run and play good zone pass defense. We will occasionally play man-to-man and blitz in this situation. On third down, we will primarily play man-to-man and mix-in some zone and blitzes. We will rush four or more players versus the pass about ninety-percent of the time.

“In all situations, we will defend the inside or middle of the field first – defend inside to outside. Against the run, we will not allow the ball to be run inside. We want to force the ball outside. Against the pass, we will not allow the ball to be thrown deep down the middle or inside. We want to force the ball to be thrown short and/or outside.

“… Finally, our job is to take the ball away from the opponents’ offense and score or set up good field position for our offense. We must knock the ball loose, force mistakes, and cause turnovers. Turnovers and making big plays win games. We will be alert and aggressive and take advantage of every opportunity to come up with the ball . . . . The trademark of our defense will be effort, toughness, and no mental mistakes regarding score or situation in any game.”

None of this is revolutionary and much of it is coach-patois (there is another section in his playbook where every position is required to put in “super human effort” or else they are deemed to have failed), but it’s a good place to start. Most good defenses begin with the premise that, to be successful, they must stop the run on first and second down to force known passing situations on 3rd down. (Which is one reason why Bill Walsh – in words far too often unheeded – advocated doing much of your dropback passing on first down.) Indeed, the book on Bob Stoops’s defense is known to everyone: first and second down expect an eight-man front and on third down you will see some kind of base or nickel personnel zone-blitz. No mystery there. A final brief prefatory note is that while Saban bases out of a 3-4, he quite commonly has one of his linebackers put their hand down and line up as would a 4-3 defensive end.

So let’s get a bit more specific. First I’ll discuss what is maybe Saban’s most common defense, Cover 1 Robber. Second, when Saban does use zones on known passing situations he likes the overload blitz and the common 3-3 zone blitz behind it, so I’ll show a basic example of what this might look like. And finally, I’ll discuss a couple coverage techniques that Saban likes to use.

Cover 1 “Robber”

Cover 1 is maybe the most common defense in the SEC. (Though “Cover 2” is close if you lump together all its variants.) Base Cover 1 is quite simple: the “1” refers to a deep safety who aligns down the middle, while all the offense’s skill guys are covered man to man. This doesn’t necessarily mean it is bump and run – it could be loose coverage – but it often is bump and run. The defense needs a great centerfielder back at Free Safety who can stop the deep ball and cover sideline to sideline.

The nice thing about this defense is it is simple and, once you’ve locked in five guys in man and a free safety, you can do whatever you want with the other five. And, maybe most importantly, with just one free-safety deep, the defense can get in a lot of eight-man fronts. On passing downs, the defense can find ways to creatively blitz five guys, have a deep safety, and all the while still account for all five of the offense’s receivers. The defense cannot really outnumber the pass protectors, but it can still collapse the pocket. That’s base Cover 1.

Cover 1 “Robber” works the same, except there are only four rushers and, along with the deep middle safety, another defender comes down to an intermediate level to read the QB’s eyes and “rob” any pass routes over the middle, like curls, in routes, and crossing routes. “Robber” is the most popular term for this technique but Saban’s is “Rat.” (I was always partial to Homer Smith’s term, “floaters,” which is the most descriptive.) There’s nothing magic about this coverage; every NFL team and most BCS college teams use it. Indeed, despite all the bluster about the Indianapolis Colts being a “Cover 2 team,” on first and second down you see lots of Cover 1 and Cover 1 robber from them, except they use their strong safety, Bob Sanders, as the “floater.” The key is for the floater to be able to read run, screen, or pass, and to use his eyes to get to the receiver and the ball. It’s particularly effective nowadays with the increased use of spread formations which most offenses use to open up passing lanes over the middle. Floaters or rat players can stop these inside passes and make game-changing interceptions. Below are some diagrams, and I expect to see Saban use this coverage a lot this season. (As a final note, Cover 1 Robber is useful against spread offense teams with mobile QB’s because the floater’s job becomes to not only read the QB’s eyes on passing downs but also to watch him for scrambles and to simply mirror the him on run plays like the option and the zone read.)


Base Zone Blitz

I won’t say too much because I’ve written extensively on pass protection and the zone-blitz here. But Saban will go to the zone-blitz in some passing situations and also when he feels like he can use the blitz in a way to attack an expected run and still play zone behind it. For example, if a team likes to run off tackle to the TE side on a particular down and distance, he might call a blitz that attacks that area and the zone blitz lets him still play sound coverage behind it. And like most modern defenses, Saban’s most common coverage behind a zone-blitz is a 3-3 or three-deep and three-intermediate defense with five rushers. Cover two behind a zone blitz is often dangerous because of the added uncovered deep seams, but most defenses feel comfortable with the 3-3. Below is a good example of an overload zone-blitz Saban uses to the open side of a one-back formation.

The thing to remember is that for years, when a team blitzed it was playing either Cover 1 or Cover 0 man (or simply left holes in its zone), and quarterbacks were coached to throw the ball where the blitzer had come from. Nowadays, there’s a common perception that a zone-blitz works because a defensive linemen gets in the throwing lane – no. What the dropping defensive end in the diagram above does is allow the defense as a whole to stay in zone coverage, and further notice who is covering the area where the blitzers came from: the strong safety, who is usually an effective pass defender, certainly moreso than a defensive end. That is how zone-blitzes cause confusion.

Other Techniques - Cornerback Leverage and Pattern Reading

Finally, let’s discuss some coverage techniques. The first is that Saban likes to have his cornerbacks adjust their “leverage” on a receiver based on the receiver’s split from the tackle and sideline. The theory is that if the wide receiver has cut his split down he has done one of two things: (a) given himself more room to run an out breaking route, or (b) cheated in to run a crossing or deep in-breaking route. So if the receiver cheats his split in, Saban has his cornerbacks align outside the receiver to defend the out-breaking route, because if he runs the in-breaking route the corner has help from the linebackers and safeties. Similarly, if the receiver lines up very wide (bottom of the numbers, let’s say), he has given himself room to run an in-breaking route like a slant. So the cornerback will align inside the receiver to take that route away and on the belief that an out-cut from that wide will be very difficult for the quarterback. To coach this Saban uses a “divider” line where they believe the receiver’s tendencies change to reflect one of the above two strategies. Nevertheless, the defensive back still must defend the route the receiver actually runs and maintain proper technique, but this is an important starting point.

More significant, however, is that Saban heavily coaches up “pattern reading” within his zone drops. The two zone-dropping schools of thought are to teach “spot-drops” or “pattern-reading.” One can overemphasize the distinction, but generally spot-dropping is easier to teach and was the traditional approach. For example, if your outside linebacker is responsible for the weak-flat, he will take his read steps and, upon reading pass, will drop to a spot and then react to the QB’s eyes. A big advantage with spot-dropping is simply that it is easy to teach to, say, a run-stuffing inside linebacker who spends most of his time on run game pursuit and shedding blocks. But the weakness is that well coached receivers – who have enough time – can become excellent at settling in the “zone holes” between defenders. And, with good receivers and good QBs, offenses have become more and more adept and finding and exploiting these zone holes.

Pattern-reading, on the other hand, is much like a matchup-zone in basketball. Defenders are responsible for zones but they basically play man on the receivers who come into their zones. Moreover, pattern-read teams begin by immediately coaching their defenders on how to recognize popular pass combinations (and indeed, the very concept of pass-combinations themselves), and each week zero in on the 5-15 most common pass concepts they will see from that opponent. When done correctly, pattern-reading defenders know exactly how to cover receivers in their zones and seamlessly (in a quite literal sense) pass the receivers onto other defenders as they run their routes. One thing that distinguishes Saban is that he uses pattern-reading in almost all of his coverages, including the traditional Cover 3, whereas many coaches only let certain defenders pattern read or only use it with certain defenses like Cover 4. Sounds a lot like Belichick, no?

Urban Meyer Q&A on his offense

The Orlando Sentinel's Chris Harry has a great Q&A with Urban Meyer. I hope I don't get in trouble for this but it's basically all worth reading. See the original link here:

HARRY: You hear a lot in the offseason about coaches going to visit different schools and exchanging ideas with other coaches for the sake of the program and professional development. How's that work here?

MEYER: "That's a big part of what we do. For example, our strength coach and my administrative assistant, every year -- and they have no choice -- have to get on a plane and go visit the best places in America and find out if we're doing the right stuff. I've always encouraged our trainers, our academic people. It's the ones who sit around and do nothing. At some point, [everybody's] going to catch you. No, that is a must. You are graded on your professional development. That's part of your evaluation. And we don't want to be frivolous. We run a certain style, so we don't want to waste time. Go see your buddy? We don't want to do that. There has to be a reason. [The concept] is kind of amazing. I tell people, I'm sure Pepsi doesn't visit Coca-Cola and figure out how to make pop"

HARRY: Where do you draw the line?

MEYER: "It's hard. We've drawn it more. It got out of control a little bit. You have so much work to do. All of a sudden, people are walking in saying, 'Hey coach, you got three hours?' No. You just don't have time. So the last few years we've kind of made it off limits. We do allow some in. If Jon Gruden calls? Absolutely. Bill Belichick comes down every year. We're certainly not going to say no to them. So we handpick who we allow to come in."

HARRY: A guy like Gruden, you never know. He could be standing across from you on a sideline one day.

MEYER: "True. But you have to get something. This is a two-way street. For Jon Gruden to come in and just take? We're not going to do that. We're not into supplying information. We're into exchanging information. A guy like Bill Belichick? I get 10 times more than what he gets from us. Same for Jon Gruden. . . . I could go on and on and on. [California's] Jeff Tedford. He's one of my great friends. We always do it. Rich Rodriguez? We used to do it all the time [when he was at West Virginia], but now he's at Michigan and a competitor in recruiting so we don't anymore. [Rutgers'] Greg Schiano. I could go on and on. Mike Leach at Texas Tech. We often have conversation. [Utah's] Kyle Willingham and I talk twice a week."

HARRY: Give me an example of something Bill Belichick could share with you.

MEYER: "Where do I start? I am amazed at the how he handles elite athletes. You never hear about issues with off-the-field stuff. I am amazed to the point that I got on a plane and I went up and watched over three days and saw how he handled these, um, some of these elite guys. For some reason, the Patriots do this, but you hear about the Cowboys and these other teams just falling apart because of chemistry issues. And then there's Bill Belichick. Our whole program is based on what we learned from him; the core of the team has to be strong."

HARRY: When was the last time you saw a play or a formation where you went, "Wow! I've never seen that before."

MEYER: "Forty-five minutes ago. I've been watching Oklahoma tape all morning."

HARRY: Really? You often hear coaches say that nothing is new; that everything has been used before. Yet when the Wildcat showed up in Miami last year, it was like the NFL freaked out. But it was old-time single-wing football, which is lot of what you do here. What was the genesis of your offense?

MEYER: Part of it is single wing, yeah. I would say there's a spread element and a single-wing element. We've combined them both. We want to have a run component. At any time, anybody can stop the run. It's just taking one more defender than you can block and putting him right there [on the line]. Unless that guy is not very good and you have a great running back, like a lot of the Big Ten teams when I was growing up. Everybody would say, 'BYOB: Bring Your Own Blocker.' He's on scholarship too, and you have to run him over sometime. That's OK. But to simply say we're going to do that all the time and score points, I can't disagree with that more. So how do you take advantage of the guy that's the extra defender? There's two ways to do it. One: you run a single-wing offense, which means you spread a guy out so that [extra defender] has to go cover him. Two: you spread out and throw the ball. We're going to do both."

HARRY: What about the single wing has given it the staying power?

MEYER: "The fact you can run the ball when everybody is blocked. You'll hear a saying around here: 'Never run the ball against an unblocked defender.' Never do it! And I'm kind of giving you everything we do here." (The next few minutes involved some scribbling and lots of X's and O's, the bulk of which, without the diagrams, doesn't translate very well in print. I can promise you, though, it was as interesting as it was informative.) [Ed. Note: Darn! I guess this is why my site exists.]

HARRY: Option football has universally been written off as something that cannot work in the NFL. There are other offenses people say, flat-out, can't work in the NFL.

MEYER: "If you know me, you know I think any offense can work if you have the right personnel back. Offenses are overrated. People are not. The NFL will take a quarterback and put him on a very bad team and call him a bust. Never mind that the defense ranks last in the league and there's no offensive line. Chris Leak [in 2005] had about as bad a three-game [stretch] as we've had at Florida that I've ever had as a coach and it just so happened that Bubba Caldwell broke his leg, Jermaine Cornelius sprained his ankle, Chad Jackson had a bad hamstring and Dallas Baker broke his ribs. And so Chris Leak struggled the next three games when we're playing LSU, Georgia. It doesn't matter what you run. It's personnel based."

HARRY: You kind of just told the Alex Smith story. Your guy at Utah. No. 1 overall pick just four years ago. Goes to a bad team. A lot of folks already have written him off as a bust already.

MEYER: "I don't want to give you names, but I can list 10 other quarterbacks who aren't doing great, too. They're West Coast [offense] quarterbacks. It's about who's on the team."

HARRY: It seems what's happened with Alex is held up as the standard for spread quarterbacks projecting to the NFL. Obviously, you've heard that rap with regard to Tim Tebow's future there, and heading into the draft people were wondering if Percy Harvin's three years of running bubble screens meant he couldn't run a simple dig and the rest of the routes on the passing tree.

MEYER: He can run it better than most; and if someone is paying him $20 million, he'll run a great dig route. It's interesting that you say that. I don't hear it a lot, maybe in recruiting once in a while, but I did hear a NFL coach saying something about that. I like to do my homework. I went and checked the record of that coach and the guy barely had a .500 record. [Ed Note: Reminds me of what Mike Leach said about Mangini.] There are certain people I'll have a discussions with. And if I hear something like that, that's not a person I want to have a discussion with. That's nonsense. That's someone putting too much value on scheme rather than personnel."

HARRY: Is your offense easy to teach?

MEYER: "Again, it's based on people. I keep going back to that, but if you have really good players, it's really easy. If you don't, it's really hard. Is the West Coast offense easy to teach? If Joe Montana is throwing to Jerry Rice, yeah, Daffy Duck can teach it. I don't want to de-value teaching. It's absolutely critical, but I'm still going to go back to personnel."

HARRY: Are you a NFL fan?

MEYER: "I'm a fan of some players, some coaches, not necessarily teams. I try to watch the Patriots, but Sundays are such a busy day. Maybe on bye weeks."

HARRY: But you study some teams during offseason, I'll bet. That constitutes professional development, right?

MEYER: "Absolutely. Every year I go to a camp or two. I've already been up to Jacksonville. Spent five hours with Jack Del Rio. Phenomenal coach. I like this new guy [Raheem Morris] in Tampa Bay. I've been invited down there. And I'll get up to New England again."

How to take a team to the woodshed with your spread offense

The spread may not always be the answer to everything, but if you can do what this team does, you don't need anything else. (Warning: This video contains images of putrid tackling, and may not be suitable for public consumption.)



(Ht HueyBoard).

Incidentally, though I generally agree with Dr Saturday that the spread isn't (and need not be) the sine qua non of someone's offense to the exclusion of everything else, practice time must be considered: Division I football teams have a fraction of the practice time allowed in the NFL, but even many high schools have more practice time, counting in summer passing leagues, spring football, and all that. And, with limited practice time, there can be benefits to being a hedgehog like Florida or TTech, and doing one thing extremely well, rather than going for mystical universality by being "pro-style, whereby the players are overloaded.

Steve Logan on the shallow cross and blitz-control

Steve Logan, currently with the Tampa Bay Buccaneers and formerly the offensive coordinator for Boston College and head coach of East Carolina, has a nice presentation on using "hot" routes in the dropback game. This is a nice companion to my recent discussion on the "shallow," "drive," and "drag" concepts. (I also recently linked to Logan discussing four-verticals.)

Only thing I will say about the Malzahn versus Franklin "we've heard it all before" debate is that all sides now admit that there were serious behind the scenes issues at Auburn last year -- regardless of whoever was at fault -- that would contribute to making any offense dysfunctional. And, of course, Auburn's offense ramained poor even after Franklin left. So continuity and support alone ought to make Auburn's offense at least a little better.

The Gus Malzahn/Auburn Tigers run game

In a conference full of coaches with championship rings (Urban Meyer, Steve Spurrier, Nick Saban, Les Miles, etc), and another who no one can stop talking about, a former high school coach continues to receive his fair share of scrutiny. And he's not even the head coach: enter Gus Malzahn, new Auburn offensive coordinator. Malzahn has been asked to deliver on the promise that Tommy Tuberville and Tony Franklin failed to; namely, a "spread" offense that actually produces.

When Auburn hired Malzahn I described his philosophy, which can be easily gleaned from the forthright title of his book, The Hurry-Up, No-Huddle: An Offensive Philosophy. As I said before, he is overall less concerned with the specific Xs and Os in employ than with the speed at which the offense goes:

There are a few differences here between Malzahn's offense and what Franklin and Tuberville tried to do (or said they were trying to do). The biggest, I'd say, is that Malzahn's spread is not exactly like other spreads, whether pass-first ones like the Airraid or run-heavy spreads like Urban Meyer's or Rich Rodriguez's. That's because the schemes are simple - very, very simple - and the core of the offense is not even about schemes: it's about tempo. . . .

[N]obody does what Malzahn does. If some no-huddle teams, like Franklin's, are light-speed, then Malzahn wants to spend the entire game in something akin to "ludicrous speed."
This past spring, Malzahn installed his offense with signs of progress, though he has yet to get everyone up to his preferred "ludicrous speed" yet. That will come. With talk about his overarching philosophy out of the way, however, it's still worth asking what his Xs and Os will actually look like. And, if spring practice is any indication, we know the answer: a lot like they did at Tulsa.

At Tulsa, Malzahn, with co-offensive coordinator Herb Hand (who deserves as much credit as Malzahn), blew the doors off just about everyone they played. In 2007, they were: sixth in scoring (41.1 per game), first in yards (543.9 per game), and third in yards per play (6.8). In 2008, after losing their quarterback Paul Smith -- who had thrown for 47 touchdowns the year before -- the offense actually improved: second in scoring (47.2 points per game), first in yards (569.9 per game), and yards per play (7.3). Much of that improvement came from the running game, which jumped from 172.93 yards per game in 2007 to 268.00 in 2008.

Indeed, Malzahn actually predicted this improvement via run game back then. After his first season at Tulsa, he did in an interview with ESPN:

Q: What makes your spread offense potent as compared to say, a Texas Tech or Missouri or a team like that?

Gus Malzahn: We're a run, play-action team. A lot of spread teams are pass first, run second. But we're a run, play-action team. As a matter of fact, I think we ran the ball one more time than we threw it last year, which a lot of people don't know. We like to be 50-50 and be able to do both well.

All that said, you can still consider me slightly skeptical of his claim to being a smashmouth guy. Back in his high school days, and even during his time at Arkansas, those around Gus always said if he had his way he would have thrown it about as much as was humanly possible. We're talking Mike Leach, June Jones stuff. But, people change, and his experience with Coaches Graham and Hand at Tulsa (much moreso than his experience with Nutt at Arkansas) appears to have heavily influenced him. Hand, a Rich Rodriguez disciple, not only helped implement many of Malzahn's ideas, he also brought many of his own to the table, particularly regarding the spread run game.

But the proof is in the pudding. I am familiar with what Tulsa did, and I finally have been able to see what Auburn implemented during spring practice. And it is much as I expected: it is a smash-mouth spread operation. Indeed, the spring offense was notable for quarterback inconsistency, yes, but also for big, big plays from the running game.

As a preview for this upcoming season I will describe three plays Malzahn can be expected to use at Auburn, none of them particularly revolutionary: the counter, the zone-read with bubble screens as a read, and the power. Each has old roots, though Malzahn will do his best to aid their effectiveness through lots of motions, fakes, and shifts. Expect the tight-ends or H-backs to play a big role in the offense in making key blocks, and also expect to see lots of wide receiver motion, with their either getting the ball on reverses or as pitch men on the option, or merely faking so.

Counter play

The counter play is age-old, though was popularized and made famous by Joe Gibbs's Redskins, though he admits to stealing it from Tom Osborne's Nebraska teams. On the "counter trey," the playside (the side the run is eventually going to) "down" blocks, leaving the defensive end unblocked. They work together to double-team defensive linemen on their way to the linebackers. From the backside, one linemen, usually the backside guard, pulls and kicks out the defensive end or outside linebacker; it is actually a "trap" block. The other component of the blocking is that another player from the backside, sometimes the backside tackle and other times a full-back or H-back, will pull and "lead" into the hole, blocking the first linebacker he sees. The runningback takes a counter step or two, and then simply follows the pulling blocker's block, and cuts off of it. Below is a diagram of how the play has traditionally been run, from the I-formation, courtesy of Trojan Football Analysis. (The diagram is of Nebraska, and see this post for a great breakdown of how the great Husker teams of the 90s ran the play.)



So what does it look like when Malzahn uses it? Well it's basically the same, except he might show a few different things before the snap. Specifically, he might use an H-back or fullback type player who comes from the backside to be the "puller" who leads into the hole, and that player might begin the play split out wide and motion in across the formation. Or, the runningback himself might motion into the backfield. There's lots of options. Below, however, is a diagram of what Malzahn did in the spring game; the play went for a long touchdown twice in the spring game (thanks to good blocking and some weak angles by the defense).



To take one of the examples before getting to the film clips, the offense lined up in a basic shotgun set, with one runningback, one H-back, and three receivers.



I have only drawn paths for two players: the backside guard pulls and kicks out the defensive end, while the H-back pulls and leads into the hole (and eventually also kicks out the linebacker, though he could have just as easily "hooked" him inside, had the linebacker stepped that way). The rest of the line just blocks down, and the runningback takes his slight counter steps and explodes into the hole, following the H-back's block. To see it all in action, check out the film clips from the spring game this past year.



If all this looks familiar, even from a spread set, it should. Compare what Malzahn is doing above with what Urban Meyer does at Florida. First a diagram, then basically the exact same play run with Percy Harvin. There are differences, but most of them are cosmetic.







Same play. Auburn is just hoping it works as well for them as it has for Florida.

Zone-read with bubble screen

I won't get too far into the basics of the zone read; I have both discussed it previously and also plan to go more in depth in the future as teams defend it differently nowadays. What you can expect from Malzahn and Auburn is much in the mainstream in terms of the play. The line will zone block, and the runningback will look for a vertical crease. The quarterback will read the backside end to determine where or not to give the ball to the back or keep it himself. The one wrinkle Malzahn brings -- which again, is something Rich Rodriguez has been doing for some time -- is to build the bubble screen on the backside in. Basically, if the backside pursuit cheats in too much, Auburn has its constraint play built in: the quarterback can always pull the ball and throw the bubble. Below is a diagram and a video of Auburn running the zone with the bubble on the backside, though the quarterback just gives it to the runner.







Power

The "power" run is another that has ancient, "power football" roots but has been adapted to the spread. And it, again, is very simple: the line essentially "down" blocks, meaning they block the men over them or to their inside, and will use teamwork to combination block the defensive linemen until one releases to hit the linebackers. The exception is the defensive end or other outside, on the line of scrimmage defender. (Aptly referred to as the EMLOS -- "end man on the line of scrimmage.") The fullback -- or H-back, or someone -- plows at him to kick him out, thus opening a crease.

The crease becomes a hole, however, because the backside guard pulls and "leads" into it to block the linebacker, or other first threatening defender. In this way the blocking works much as it does on "counter," but with more of a frontside attack. Below is a diagram of how an NFL team runs the play; it is in every NFL team's playbook. (Click on the diagram to make it larger.)



And below is a common look Malzahn ran "power" from while at Tulsa, using the "pistol" (short shotgun with the runningback directly behind the quarterback) and a cross between an H-back and a fullback. See below.



This will be a common set for Auburn. Malzahn likes lining up with three wide receivers, but then also likes the versatility of the H-back/tight-end/fullback type as a blocker in a variety of directions. Again, compare his straight ahead blocking on "power" with his about face to the opposite side on "counter." (And with the pistol set the runningback could go either direction.)

Conclusion

So this is about what you can expect: some basic plays -- including power plays -- from spread sets with lots of shifts and motion, all at a top speed. Malzahn will try to go for some play-action and big plays off of this; I may diagram some of those later. How well it all works will depend on execution, particularly by the quarterbacks. Time will tell.

But a final thought. Another thing to expect from Auburn's offense this year will be lots of motion from the wide receivers and their use as a threat to run as well as catch. Now, all of these "versatility" roles -- H-backs and receivers as running threats -- depends on depth and skill at those positions (easier if you have Percy Harvin), but Malzahn likes to to give the look so as to at least present the problem to the defense. From the "power" look above, Malzahn likes to motion an outside wide receiver completely behind the runningback, and he then gets into a pitch relationship with the quarterback for an option. This way Malzahn can fake the power play and run the speed option with the quarterback (Kodi Burns?) with the receiver as a pitch man. It's fun stuff, at least when it works. Once he has done that, the very fact of the receiver in motion tends to help draw defenders when they do simply hand it off to the runningback on the power play.

Will it work in the SEC? I don't know, but if it does, expect plays like the one in the video below to be on all the highlight reels. Notice how the motion by one receiver sets up the sweep in the opposite direction by the other. With Malzahn's offense, don't just try to watch the ball, because that will rarely ever tell you where it actually is.

Deal or No Deal and incoherent views of "trade value"

Apparently, Broncos receiver Brandon Marshall is on the trade block, according to Shutdown Corner. The headline of his piece is called "You just cannot get equal trade value for Brandon Marshall." That's not a per se inaccurate statement, but it presumes you know what "trade value" is. Presumably, by the way it is used in the post, "trade value" equals the value of the productivity or talent the player is capable of. But we all know that a player's "value" is influenced by many factors aside from their raw talent, including his salary, his adaptability to what other teams do, and, particularly in Marshall's case, the likelihood that he will be around to perform and not caught up in the legal system. Shutdown Corner:


Look at it this way: If the Broncos pay Marshall and hang onto him, one of two things happens: He either stays healthy and out of handcuffs and is an extremely productive player, or he ends up suspended or in court again, in which case, the Broncos don't get the value they should.

If the Broncos trade Marshall, though, they also don't get the value they should. Period.

So the only possible way to maximize what you get from him is to roll the dice, keep him around, and hope you get the best out of him. In any other scenario, the Broncos lose.

The italicized conclusion does not follow from the premises, and largely contradicts #1, that they keep him and "he ends up suspended or in court again." The key issue is that there is something they "should" get. Should Marshall be "worth" more, based solely on his talent? Yes, but the fact that he isn't is due solely to himself; it is not something the Broncos have any control over. They must take their troubled receiver as they find him.

Indeed, while value of a player is some estimate of their probable production, that value is a calculation their talent and capability multipled by their risk of injury, off the field trouble, discontent, etc. You don't produce if you're not on the field, and we've seen otherwise talented players be traded for peanuts or released because they weren't "worth" what they were being paid. See Terrell Owens.

Trade or No Trade? The upshot is that SD's conclusion -- that the Broncos must keep Marshall -- doesn't follow, because it confuses "maximizing" expected gain with maximizing the possible gain, two very different things. This is a common cognitive defect, particularly after someone experiences a setback or dramatic loss in value, much like the Broncos just have as their star receiver has been in increasing amounts of legal trouble.

The show Deal or No Deal provides a great example. Much has been written about the show from a behavioral economics perspective. I will assume people are familiar with the show's basic premise that someone selects a case, and then takes other cases off the board which whittles down the possibilities of what are in his case. Throughout the show, a "banker" offers the player a certain amount of money to walk away, based on what possible values remain in play.

Let's say our contestant -- let's call him Sonny Chiba -- has four cases left, with possible values of $10, $100, $500, and $50,000. The case he just chose took $100,000 off the board, so he is reeling a bit and is no doubt upset about the money he just saw evaporate. The banker gives him a new offer: $16,000, significantly down from the previous one.

What should Sonny do? Take it of course. The expected value from the four cases is only $12,652.50, and moreover he has only a 1/4 or 25% chance of having more than $16,000 in his case. In the actual game, this is not an uncommon circumstance at all; the banker is usually generous after a big blow late in the game. But you know what the studies show? After a big loss that dramatically cuts the contestant's expected value and, in turn, the banker's offer (even if it is in fact still a generous one given the circumstances), contestants repeatedly reject the offer. Why? Because all they can think about is that big $50,000 maximum, and how it will compensate them for what they lost. Nevermind that it is unlikely, and that they are staring down a better offer. (I ignore here the fact that $16,000 might be too paltry for some players. Fine, repeat the scenario with 10, 500, 1,000 and 250,000, where the player has just had 500,000 taken off the board.)

Denver's Choice. No offense to SD (who I very much like as a blogger, and I am merely nitpicking out one random statement in a blog post), but his rationale seems to be that the Broncos must keep Marshall because there's a chance it might all work out and he'll be a pro-bowler. That is the same trap that our contestant fell into in our Deal or No Deal example.

Now, this doesn't mean the Broncos must trade him either; we don't know the corresponding offers with as much certainty as Deal or No Deal, either. And he's right that the Broncos probably won't get a fantastic offer because of Marshall's off-the-field problems, but that's to be expected. If believed, SD's logic would be to expect other teams to have traded for Mike Vick or Plaxico simply because of their immense talents without regard to the probability of their spending all or part of the season in jail, or otherwise or caught up in the legal system.

The upshot is that "trade value" should not be confused with the maximum possible upside. Yes, Marshall has big upside, but all the risks surrounding him bring that value down, just as it does for Plaxico, Pacman Jones, Vick, T.O., or even guys on the total straight and narrow who are an injury risk. Just because a player might be great, or has the potential to be great, does not necessarily make their trade value better than another player. There's a difference between upside and realistic expectation.

What it means is that the Broncos -- or another team that might trade for Marshall -- must understand not only what he is capable of but what baggage and risks are attendant as well. In other words, if the Broncos get what they think is a good deal, they should take it. And if Marshall winds up making the pro-bowl elsewhere, then they can (or at least should) be able to safely say that they made the best decision they could under the information they had.

Sonny Chiba could say the same thing if, after he took the banker's offer of $16,000, Howie Mandel opened his case to reveal $50,000. That's just how the game goes. It doesn't change the fact that his decision was undoubtedly the correct one.

The shallow cross, drag, and drive in the west coast and spread offenses

The shallow cross route is not a new topic for this site. Just the other day, in discussing Trojan Football Analysis's great breakdown of how Georgia's Mark Richt runs the route, I mentioned some of my previous discussions of the route itself as well as some of its common combinations. Those links can be found here, here, here, and here. Also check out the "jerk-route" variant. When teams began to go to the spread years ago by replacing tight-ends and fullbacks with wide receivers, they needed something to do with those wideouts. The shallow became an obvious answer for several reasons: (a) with fewer pass protectors, a quick breaking built-in "hot" route (over the middle no less) is exceptionally useful, particularly since the receiver breaks right in front of the quarterback for an easy throw, (b) the shallow keeps consistency with route concepts designed for two-back sets because the receiver simply replaces the runningback's role as an underneath outlet in the progression, and (c) especially in the spread's early days, defenses tended to cover these extra receivers with linebackers who were ill equipped to chase a receiver for twenty or thirty yards, even if the direction was lateral and not vertical. (The route has some limits: it gives easy cues for pattern reading by the defense.)

There's a couple variations in how the shallow is used. Typically, a shallow route is combined with some kind of ten to twelve yard square-in route behind it. The question is from which side does the square-in break from: is he coming from the same side as the shallow -- i.e. trailing him? Or is he crossing over the top? This matters because it makes a big difference between what kind of flow you're looking for from the linebackers and where the windows in the zone will be. The Airraid guys tend to have the two guys cross and head in opposite directions. the diagram below.



(Image courtesy of Bruce Eien; check out more notes on their version here.) For clips of this version of the concept try here and here. It's a great concept: the shallow pulls the linebackers while the square-in -- aptly known in Airraid terminology as a "hunt route" because the receiver "hunts himself a good place to settle down" -- find the void between defenders.

I am concerned in this post, however, with an older version of the shallow. This is the "drive" concept, made popular by Bill Walsh as a way to get his flanker or "Z" receiver (Jerry Rice, hello!) the ball running full speed across the formation. Secondarily, if they covered Rice there was usually a big window in which to throw the ball to the tight-end. Below is a diagram of how Walsh ran the play from several different sets, straight from an old 49ers playbook.



First, a few features of Walsh's version. Keep in mind a very basic fact that many NFL announcers do not understand: The slant and the shallow are not the same play. On the slant, the receiver takes between two and four steps upfield (I prefer three, beginning with the outside foot back) and then a 45 degree break. The quarterback takes a three-step drop and delivers it quickly. The shallow, on the other hand, takes awhile to develop. The quarterback takes a full five-step drop (and sometimes seven, or five from shotgun) and waits for the receiver to at least cross the centerline. Again, it was Walsh that helped systematize these plays, though they preexisted him.

Anyway, his "drive" route, as he called it, begins with the shallow. Walsh often motioned his flanker towards the formation to enable him to explode through all that man-traffic so he would hopefully emerge free and clear on the backside. If the defense was in was man-to-man -- especially loose man-to-man -- the cornerback usually had a hell of a time trying to catch up with the receiver. But if the defense did cover that route, the tight-end was responsible for finding the void in the zone. The final read was the runningback as an outlet.

But, before getting to those routes, the quarterback always retained the option to throw deep to the corner route or the "go" route on the backside; typically this was the case if the defense was in man to man and he saw a matchup he liked. Note how Walsh sometimes had the corner route run by the halfback in the backfield -- think of Roger Craig or Ricky Watters with a linebacker assigned to him. Alternatively, sometimes the cornerback and near safety were so concerned with the flanker and tight-end that they collapsed down, leaving the runningback or slot man to break wide open on the corner. Nowadays, many modern teams send the runningback on a "wheel" route -- i.e. begin the route like you are running to the flat on a "shoot" and then turn and "wheel" it up the sideline. Below is a variant Bobby Petrino has used in the past at Louisville, the Pros, and now Arkansas.



So where are we now with the play? There have been a few changes in how most teams use the route and concept, especially since now that so few teams base out of two-back sets. As a result, the shallow is seen more as a route for inside receivers than a way to throw it short to your flanker. Below is a diagram of one of the modern versions (as you can see, quite similar), explicated in rich detail in Dan Gonzalez's book, Concept Passing: Teaching the Modern Passing Game. Gonzalez calls his route concept "drag."



So the basic route structure is the same as Walsh's drive. The major differences are that interior players are used, that the outside receiver to the trips side is given a post route to exploit a safety who might play the square-in too aggressively, and on the backside the X is a greater part of the play.

The quarterback isn't always told to read the comeback, but if he does he keys the outside linebacker to that side. See the diagram below, the man circled in blue. If the linebacker drifts where he is or takes the shallow coming to him, the quarterback can drill the ball to the comeback on the outside. If the linebacker heads quickly to the flat to take away the comeback, the shallow route should come wide open in the void he has vacated.



The rest of the play works just like Walsh's drive: either the shallow or the square-in should come open depending on who the linebackers pay attention to, and if neither is open the runningback should be open. Below is footage of the play, thanks to Dan Gonzalez and Mav (first clip), and Bruce Eien (second clip). Bruce's differs slightly but is similar enough to be grouped into the same family.





and





The film by Eien, directly above, is basically a cross between the true, old school "drive" and the Mark Richt/Florida State version, which again is the same "drive" concept but applied to a more two-by-two setting. For more on Richt's version, check out Trojan Football Analysis. Below is a diagram and cutups of the concept as another comparison.







Conclusion

As evidenced by my old post on how Mike Martz used the route, the shallow's usage is limited only by the imagination. It can be the primary route, the hot route, or a secondary route for the quarterback to come to late in his progression. It can be run by any receiver, and can be part of a main concept or used in some auxilliary way. But however it is run, it is still one of the best ways to get the ball to a playmaker -- speed in space -- and so long as teams keep spreading their formations, they will keep using the shallow cross.

Bonus - Video below of Mike White, then head coach of Illinois, explaining the now-Airraid version of the shallow cross. His quarterback at the time was Jack Trudeau. After diagramming the play White shows the square-in or "hunt" going for a big touchdown against one of Bo Schembechler's Michigan teams.

The most famous "smash" of all?

I've previously deliberated on the "smash" concept at length; it's one of the best passing plays, a staple of every modern passing game, and was in many ways one of the transition concepts from the dark ages to today's sophisticated passing attacks. The basic concept is a simple one: an outside receiver runs to about five yards and basically turns around, while an inside receiver runs to about ten yards and breaks for the corner. The idea is for the outside receiver to hold the cornerback shallow while the corner route breaks open behind him. See the diagram below.



I had long remembered this play, but I was delighted when I saw that Every Day Should Be Saturday tracked down the famous use of the "smash" concept by Auburn (then coached by Terry Bowden) to beat Florida. The video below is self-explanatory; the smash concept could not be demonstrated more clearly.

Darrell Royal on tackling

Old school. Part I



and II

Smart Notes - June 15, 2009

1. Mark Richt on the shallow cross. Trojan Football Analysis has a great article on Georgia Head Coach Mark Richt's shallow cross series. I have discussed the various forms of the shallow previously here, here, and here. (Also, Wayne Wilkes's book, Coaching Fast Break Football: Adapting the FSU Offense to High School Football, which is about the Charlie Ward era no-huddle spread Richt and Bobby Bowden used at Florida State, dedicates several chapters to this route and its variants.) TFA breaks the play down, and includes over forty minutes of Richt's presentation on the route, where he describes its history and application. Below is a diagram of the base concept, along with the shorter cutups. Both courtesy of TFA:






The shallow, in all its forms, is a great route. Indeed, in some ways it was the foundation for the early spread offense; as teams began to employ four receivers on every play and opened up the formation, they often found it useful to have at least one receiver on a deep route (to threaten the coverage as well as to clear it out) and one shallow cross (to work well against man and as a "hot" route for the quarterback against the blitz) on every play. But with the rise of robber coverage with a "floater" over the middle, better covering interior defenders like nickel backs and linebackers, less all-out man blitzing and more zone-blitzing, and overall better pattern recognition, the shallow has seen its effectiveness wane a bit. It is still a go-to play, but it has a different, more limited role. Art from TFA actually asked Richt about all this:

I spoke very briefly to Coach Richt later on during the day when he was taking questions from attendees in another room before he left. I asked him a follow up question about the plays somewhat declining effectiveness compared to the Florida State years. Coach Richt replied that he used to think it was easy to make the play work. However in reality and with the benefit of 20/20 hindsight it was also special players like Charlie Ward and Warrick Dunn that made it so effective in the past. Also he thought the best defense versus the play is a Cover 2 scheme which is now so common. This defensive alignment often makes the play essentially just a Hi / Low “Smash Route” type read to just half the field versus the flat defender. This adjustment can be accomplished either on the front side or back side with minor alterations to the play call. Still the Shallow Cross is a very effective play but not quite what it used to be in the past. Also Coach Richt conjectured that many defensive coordinators down South learned not to blitz the play (he wishes they would however) as that gave up many big gains and easy TD’s in the past.


2. Coaching timidity. Advanced NFL stats has a great follow-up to my articles (here and here) on underdogs and risky strategies. Money quotes:

In the NFL as a whole, visiting teams average about 19 points with a [standard deviation] of 10 points while home teams average about 23 points with a SD of 10 points. But unlike basketball, football opponent scores are negatively correlated. This makes intuitive sense because the better one team does, the worse the other should do. . . .

Here’s why underdogs should play aggressive and risky gameplans. Take an example where one team is a 7-point favorite over its underdog opponent. Say the favorite would average 24 points and the underdog would average 17 points. With a [standard deviation] of 10 points for each team, the underdog upsets the favorite 31.5% of the time. . . . [I]f the underdog plays a more aggressive high-variance strategy, increasing its SD to 15 points, it would upset the favorite 35.3% of the time.

. . . . So what does any of this mean in the real world? Simply put, to win more often underdogs should employ a high-variance strategy from the beginning of the game. It shouldn’t wait until the 4th quarter and become desperate. Go for it on 4th and short, run trick plays, throw deep, and blitz more often. Roll the dice from the get-go.


Amen. One of the real insights of the article is the proof that variance is good of its own right, even if the "riskier" or higher variance strategy doesn't net the underdog any more expected points, the simple act of variance will net it more wins over time (though with the trade off being more blow-outs).

3. Life as a game. Every Day Should Be Saturday waxes elegaic about the rigid morbidity of football and why this sometimes reassures us, and other times is unsettling. I quote at length, because any less would not do:

This all comes back to your focal event . . . , or the instant where you realized the game had some kind of parasitic, infectious grip on you that no amount of treatment would undo. . . .

No injury time, no second chances: just a minute and change left on the clock bleeding because the rules dictated it and demanded you respond. Every football game dies one second at a time, bounded by a thousand rules, and played out by teams of fragile people working under pressure to be as good as they can possibly be under the circumstances.

Its stricture gives it its drama, its limits force creativity, and its scarcities give it is masochistic cost/benefit payoff. More relevantly, football’s economy gives it emotional resonance. If you’re watching it, you watch it because you see a neatly packaged simulation of life itself–ruled, defined by a beginning and an end, and often chaotic in spite of all the rules–with two satisfying twists.

First, an actual victor is declared, something very rare in life. Second, you know roughly when it’s going to end. Because of this football, for all its violence and terror, will never be as deeply terrifying as life itself. (Even when Terry Dean throws four interceptions in a single game.) Without the clock, without triple zeros set between the bounds of a field precisely 160 feet by 360 feet awaitig you, meaning is debased, and we’re not left staring at the death sentence spelled out in incandescent bulbs on the Florida Field scoreboard 15 years ago wondering what the hell just hit us.



All of life is in these moments, captured and replayed for us every weekend, every fall.

4. EDSBS to CBS? In the wake of the block-buster (for the sports blogosphere at least) deal between NBC and Pro Football Talk, might CBS Sports be interested in the blog run by a good Mr. Swindle just mentioned?

5. Maybe, Definitely; Brett Favre is coming back. So says Shutdown Corner after watching John Madden's adopted son on Joe Buck's new show. (Which had a rather interesting opening episode, featuring Artie Lange.) I don't have Favre rated all that highly, but I suppose from the Vikes' perspective the question is merely, "Is he better than Sage Rosenfels and Tarvaris Jackson?"

6. Lane Kiffin death-watch. The verdict from around the web is increasingly in, and it is that Lane Kiffin must be insane and there is no way the Volunteers can succeed, and that he cannot be credited with knowing what he is doing. For some of the best weigh-ins on this, see Dawg Sports, mgoblog, and Senator "I just don't get it" Blutarsky. I am not sure if I completely agree, but I will say that, after watching the man commit NCAA infractions on national television in front of a live film crew, I find it difficult to imagine what he does think he is doing, exactly. And, surprisingly enough, he is beginning to make Al Davis look smart for firing him.

... But ... but . . . his coaching staff is so credentialed. How can Jim Chaney, Orgeron, and Monte Kiffin not know about this? Not have an opinion? Why would they accept this job if they didn't think this was going to work? Why can't they, apart from their supreme leader, make it work?

Maybe Lane will turn it around, maybe he'll be proved a genius. But his tenure at Tennessee might be a study in management, as much as anything else. If a sort of CEO-style figurehead head coach had Kiffin's staff -- like Joe Paterno, for example -- I think everyone would have to assume that it was all going to work. There might be benefit in Kiffin's just getting out of the way. But that's not his style, and it is ambiguous right now what exactly he's bringing to the table. Maybe the excitement and all that is enough, though. Time will tell. Very bizarre though. But so long as they have that staff, you can't count them out.
