cover two zone
We shall have to *press* our *quarters*. Ha ha! do you smoke the pun dear Maturin?
We've been talking about how Michigan State's defense worked and how Michigan's this year and in the future could be using that as a model. I've brought up how the 4-3 over works, but the genius of Dantonio's defense is really in how he does coverage. Since it seems this is what Michigan will be doing, I thought a lay understanding of it wouldn't go amiss just now.
Coaches, you can offer corrections or tune out because this is going to be a little more basic. Spartans, try not to be too offended at the butchery I make of your wonderful defense. You are truly our state's top program and in no way does continuing to whine about a statement a 21-year-old made in 2007 make you petty.
Now let's go to the alignment above. We're looking at a 4-3 over; the defensive line is shifted to the "strong" side (technically Michigan's offense is balanced but the side with the two TEs is strong. Also that's the field side). We're also looking at a defense that is really creeping up. The safeties are 7 and 8 yards off the line of scrimmage, the linebackers are 4 yards off, and the cornerback at the bottom of your screen is in press. The variant on the 4-3 over is the defensive ends spread out (the SDE is in a wide-9 tech, the WDE completely outside the RT's shoulder), and the linebackers group in closer to compensate.
This is "aggressive." The guys apparently in charge of the deep part of the field are further off the line of scrimmage than the running back. There's a mismatch on your right, where a cornerback is matched against a tight end (Butt), but that hardly matters since any run is going right into a pile of bodies.
Cover 2 and Cover 2 Man
Getting up and bothersome to any receivers near the line of scrimmage has big benefits. The receiver will have a hard time getting into his route, throwing off the timing of the play and ensuring the offense gets nothing cheap like a quick out or in. A good press corner will prevent his receiver from getting into an easy route like a slant (the old fashioned man-coverage beating route). The danger of this is the press doesn't work all the time and then you've got a receiver accelerating downfield past a cornerback who's facing the wrong way. For this reason press teams would leave the safeties back to help. It ends up functionally not that different from Cover 2.
Of course that has a downside as well. While each receiver has 1.5 guys occupied with him, you've got the safeties and outside linebackers chasing the passing game instead of manning the run gaps. Defensive rule numero uno is don't be easy to run on.
A very popular alternative these days is Quarters. The link will explain further but simply put, with quarters coverage the cornerbacks and safeties have option routes depending on what the receivers do. They watch the inside guy (in a stack it's the back guy). If he goes vertical the safety has him; if he goes into the flat, the cornerback does and the safety plays Cover 2.
Watch this gif from the above link until you get a feel; the left side is the #2 receiver going vertical and the right side is him going into the flat.
"Going vertical" as I learned it, is the receiver going 8 or more yards downfield before making a turn. This is a strong coverage technique to cover the outside and downfield stuff the receivers will do, and leaves the linebackers available to cover short Cov 2 routes and react to the run. It's very base; the best way to beat it is to have your running game outmatch their front seven. The safeties are able to stand back and read, so like Cov 2 they're available to cut down whatever made it through. That's good enough for Virginia Tech, who's been running Quarters and been solid against the run for a decade and a half. But it wasn't good enough for Dantonio.
Very Aggressive Quarters
You may have already smoked out the difference between Michigan State's alignment against Michigan and the Cover 4 look that quarters starts out in. You've got that cornerback pressing a guy, for one. And the other thing: if the coverage is waiting until the inside guy is 8 yards downfield to be sure of their decision, and the safeties are standing 7 yards off the line of scrimmage, aren't they setting themselves up for one of those "hey maybe I oughtta be chasing this guy who just ran by me." things?
State will pack their guys in the box so linebackers and safeties are right there to stop the run. The linebackers squeeze laterally into the box, so the coverage is strongest inside (knowing this, offenses don't typically expect to find open guys there, leaving those LBs free to run Narduzzi's favorite Double-A gaps blitz).
That makes them very stout against the run, but should have a weakness tradeoff against outside passes. If the #2 receiver goes vertical the safety has to turn and go with him, meaning there's zero help for the cornerback.
State's answer to that: "So what!" This is where stretching the boundaries of pass interference comes into play, because the cornerback's job is to grab anything, pay off anybody, or sacrifice however many livestock and virgins it takes to keep that receiver from getting downfield.
Here's where Dantonio's program development comes into play, because it takes a long time for cornerbacks to get to the point where their press will work often enough that the quarterback stops expecting that guy to be open. Also they have to be ready for what coaches will do to screw with them.
It's also where finding good players comes into play. You can't get away with this if you have crappy Indiana safeties. There's tremendous strain put on the defensive backs to play up and still cover deep; if they can't handle it (and the offense has any kind of downfield passing ability) the jig is up.
In the defense's favor: in the college game, especially the game today where Tom Brady wannabes are less common than Denard Robinson wannabes (i.e. guys who are running threats but hardly devastatingly accurate deep passers), an offense that can rip you over the top is a rare cove indeed. The talent-depleted Big Ten has been short on defense-stretching receivers; a good 40% of Big Ten wideouts who'd pose a major threat to this scheme play for Maryland. Braxton Miller has a lot going for him but he tends to sail such passes over his open guys' heads. Devin Gardner, especially a beat up Devin Gardner, has a tendency to underthrow, turning open receivers into a game of Five-Hundred. Hackenberg might have success but his best targets are tight ends; Sudfeld has a similar problem now that his slot dude is the last man standing. And omigod can you just imagine what happens when this thing meets Gary Nova? "Like a Wrecking Ball" don't enter into it!
Last year Borges tried to screw with the Quarters reads by making it unclear who's the #1 or #2 receiver to that side, either with stacks or putting 3 receivers to the same side or like this (watch the WRs at the top of the screen):
Michigan ran just a two-man route, motioning the outside receiver into the inside receiver. Ultimately Funchess leapt a million feet in the air to beat Drummond to the outside, but look how seamlessly the Spartan defensive backs executed this and made it hard.
A novice might have a hard time with who's 1 or 2, but not a 5th year senior. Dantonio built his program, like Wisconsin's, on retention. He'll hold onto guys for three or four years usually before they see the field (or else the kids have to beat out the upperclassmen). It also makes those elders kind of crucial because the depth chart carries a lot of pressmen in training.
So for the first few seconds of the play, it's kind of Cov 2 man with everybody so bunched near the line of scrimmage that the run game will be right there and obvious, and thus easy to stop. Then quarters rules take over. And it can't be cracked wide open because pass interference isn't likely to be called unless you're playing at Notre Dame.
Can Michigan do this? Actually it's probably the best thing for the defensive personnel the coaches have collected, since the one thing we seem to have a glut of is really good cornerbacks, and more in development.
Alex Kile's pointless game winner [Bill Rapai]
And it was the most pointless of all events. Michigan got a 2-2 tie out of a tightly contested game against a quite good Ferris State outfit on Wednesday, and fans were treated to a shootout at the end. The shootout decided nothing and meant nothing and took about 85 shooters to complete, but it was superficially fun all the same. Wow experience.
Anyway, Michigan staged an epic comeback in the shot department after a first period that Ferris dominated there and on the ice. M went from 14-4 down to 22-22 after two and went toe-to-toe; in the third they were held without a shot for a long time mostly because they kept tipping the puck two inches wide of the post, agonizingly. Ferris's tying goal came on a screened shot where it looked like Nagelvoort was unaware of who even had the puck and was badly positioned; other than that he was pretty damn good.
Michigan needs Kevin Lohan back, and soon, so they can sit Clare. Clare saw a potential two-on-one developing at center ice and decided to charge it, for the rare center-ice pinch. Upside: Clare gets the puck just outside of the blue line with three M skaters in the offensive zone. Downside: two on one featuring Sinelli as the last guy. Completely insane decision, one of many.
Other than that, a damn good game between two good teams without a lot of offensive wizards on their roster.
GO AWAY. EVERYBODY GO AWAY. Pat Narduzzi turns down the UConn job, which makes perfect sense. Bob Diaco then takes it, which doesn't but does mean Notre Dame has lost both its coordinators this offseason. Offense hardly matters since that's Brian Kelly's show; Diaco's departure might put some wobble in a unit that's been pretty good ever since he figured out how to defend Navy.
ND players certainly freaked out about it. Stephon Tuitt in a since-deleted tweet:
It is called that, Mr. Tuitt, and my suggestion to you is to do the same.
As for Narduzzi, he seems to be holding out for a job that is not an AAC death trap. This is probably the right idea. Unfortunately for Michigan fans hoping for some shakeup in the MSU program, with all the heads on the table save Mack Brown it doesn't look like there's going to be an opening of appropriate attractiveness this offseason unless someone gets poached by the NFL late. I'll pencil him in as Illinois's coach starting next year.
Coaching trees. Diaco is the third Brian Kelly assistant to get a head job (Charlie Molnar is at UMass and Chuck Martin was just hired at Miami). Current head coaches from Carr/Hoke era assistants after Ron English (understandably) lost his mind at EMU:
- Brady Hoke, Michigan
- This is not a tree.
- You need branches for that.
- It's a coaching line.
With Mattison and Borges not candidates for head jobs due to a variety of factors, that's not going to change. Hell, the only Michigan guy under 50 to have reached a coordinator spot is Scot Loeffler, who may not be long for that role after one-year stints at Temple and Florida were followed by a miserable opening year at Virginia Tech.
That's alarming. Compare Carr's coaching tree to Bo's… actually don't even bother doing that, compare it to Gary Moeller. It's not good that the only major school still willing to hire Michigan coaches is Michigan.
YES GO AWAY. Braxton Miller's looking at the NFL:
“It’s tough,” Miller told the Tribune. “I just don't know. I’ve really got to sit down and go through the pros and cons. I’ll talk to my parents, take it slow.
"Hopefully ball out on January 3rd and see what the scouts are looking at.”
The NFL is looking at Braxton Miller and seeing a guy who's nowhere near an NFL quarterback right now, so this probably won't come to anything. But it should. Go away!
I like big Butt. Sorry. Inevitable that was going to happen at some point. It couldn't be helped, really. Here's why it happened:
Butt entered his first year at Michigan as a scrawny, 6-foot-6, 209-pound prospect with potential.
He'll leave it some 37 pounds heavier, at 6-foot-6, 246-pounder with 11 percent body fat and an appetite for much, much more.
"(The coaching staff) wants me at 255, but I think I can get to 260, I'm a skinny 246 right now," Butt said. "I can put on more."
That is a crazy amount of weight in one year. Contrast that to Devin Funchess, who was listed at 235 as both a freshman and sophomore. While that lack of weight gain was mostly due to the roster lying its ass off about Funchess as a freshman, hey look one of those guys is a tight end and the other one is a wide receiver who occasionally puts his hand down.
If Butt can get to 260 by next fall, Michigan could have an actual dual threat tight end. This would make everyone happy: Borges would have a guy who's an actual matchup issue and I wouldn't have to watch Borges put tight ends on the field over guys like Dileo when that makes no sense at all.
Come on baby.
You wouldn't even recognize my blocking (back in the spring compared to know), I didn't know which foot to step with or where to put my hands, it's night and day," Butt says. "I look at the film and wonder 'who is that kid?' The coaches here put a complete transformation on me."
They're going to play tight ends; hopefully they'll have one worth playing.
This used to happen all the time! Michigan's safety play was not great this year but got a lot worse once Michigan started futzing with their starters, inexplicably at first and then apparently injury-forced, and I still don't get why Michigan was so down on Thomas Gordon. Was he great? No. Did he do this?
For instance, below Michigan State packages mesh with a smash variation combining a corner and swing route. The goal is to put a man beater to the boundary and a hi-lo stretch to the field against a cover 2 corner.
At the snap, Cook reads cover 2, so he knows he is going to the wide side of the field, where he has the 2 on 1 against the squat corner. Cook knows that the corner must cover the swing to the wide side flat, and he can throw the flag pattern before the cover 2 safety can react.
So Michigan State has a good call against the Buckeye coverage. But a completion is one thing. Throwing gasoline on the fire, Corey Pitt Brown takes a horrible angle, coming under the throw and violating a cover 2 safety's primary rule, which is not get beat deep. Seventy-two yards later Michigan State was up 10-0.
No. He was a boring person who did boring things like be a step late on well-thrown corner routes. This is pretty good in the grand scheme of things.
Given what we saw out of Avery and Furman when they were inserted it's clear no one was pushing through; messing with the safeties was a counterproductive move likely borne out of panic about the offense making the defensive coaches try anything that might improve the defense. By the OSU game their hand was forced by Wilson's injury, which is one of about ten things that may have cost Michigan that game.
Compare and contrast. Michigan State got inundated with Rose Bowl ticket requests to the point that they had a choice: cut out some low end folks or reduce available tickets for big ballers from 6 to 4 and medium ballers from 4 to 2. They went with the latter.
"At some point, you have to be true to the character of your institution, your history and fanbase. We're not elitist. We realize we have tremendous fan support and we know the sacrifices people make to be donors.
"The decision was made to be in line with the inclusive character of our university," Schager added. "The bottom line is Michigan State University wants to accommodate as many people as possible (for) this experience that everybody wants to be a part of."
As soon as Michigan got a good basketball team, they reseated Crisler such that people who had put in the time to watch ten years of dreck got booted upstairs if they weren't huge donors.
And there's not going to be a pep band on Saturday… for some reason. The pep band people are irritated, so it's not them, but it seems insane for even Dave Brandon to try to milk some 100 extra seats out of one regular season basketball game. That appears to be the case, though.
One of these athletic directors is making decisions based on building loyalty with his whole fanbase; the other is still running a company that markets cardboard as pizza.
Amir Williams! Oh man I feel your pain, Amir Williams.
Shouldn't Spock be in this?
Hi. Me. Back. So before that much-appreciated vacation, I used this space to talk about constraint theory of offense and provide a rock-paper-scissors matrix for offensive/defensive play calling in various offenses. Today I'm on to Part III, the one where I tell you that Rock-Paper-Scissors is only a fraction of the football head game, because the actual decision trees are far too complicated for even a coach to play all of the interactions, let alone teach them. Moreover, unlike in RPS, or super-advanced-nuclear-capable-canid RPS, there are levels to things: scissors cuts paper better than it cuts (but still cuts) woven kevlar.
Rock-Paper-Scissors is a game you learn to play on the bus ride to school in 2nd grade or thereabouts. It is a very simple, 2-dimensional, triangular matrix:
…meaning every point interacts with every other. It's one dimension past a coin flip but you still only need to remember three interactions (yellow lines). Based on your personal capacity for testing the limits of social institutions, you either very quickly or eventually tried to insert an additional dimension to the triangular matrix, and realized that you were exponentially increasing the amount of interactions you had to remember.
Your 2nd grade mind didn't draw this; it just exploded the same way it might if you interlaced Grbac to Howard, Wangler to Carter and Robinson to Roundtree into the same video. Then it came up with a brilliant way to add a point without adding dimensions:
Bazooka!!! Bazooka blows up rock. Bazooka turns scissors into mangled slag. Bazooka leaves only scant streaks of carbon where once was paper. This idea is not totally silly, since defensive coordinators call bazooka like all. the. time.
Bazooka = Vanilla
Just as the offense wants to get really good at one basic thing and then do that thing all the time, many defenses are deploying the same concept. It's a bit harder for them because they have to react to various offenses on the schedule and various plays, but the concept's the same: the defense wants to stay in a scheme that is basically sound, and will mix in blitzes and different coverages as constraints, so that they can keep running their well-practiced, mostly sound blanket defense. Bazooka is a jack of all trades, solid against the run, solid against the pass, solid against tomfoolery, and vulnerable only to great offensive play and their own physical/mental limitations.
Defenses are a bit more varied than offenses but the most popular vanilla D these days, as I mentioned in the earlier discussions, is a Cover-2 zone (above-left) against run-first teams, or the Tampa 2 against pass-ier teams (above-right).
The difference between those two is in the MLB's coverage duties—in a Tampa he has the deep middle, in a regular Cover 2 he has the short middle and can be more involved in the run game. Everybody, including the cornerbacks, are hovering around close enough to gang-attack running plays like a pincer; and soft spots in the zone (everyone has them) are relatively small and difficult for non-accurate quarterbacks.
If these guys are all reacting correctly and aggressively to the run, if the cover guys are fast enough to close their zones, and the four rushers can generate pressure with regularity, this defense can bazooka anybody's rock, paper, scissors, candle, Vulcan, or whatever. Of course that is way easier said than done—remember offenses are recruiting, training, practicing, and designed for attacking this scheme.
Offensive rock is made to beat defensive bazooka. I want you to look at the above and imagine various offenses succeeding against them. ISO running forces the linebackers to read run, read the hole, and get there in time to take out a lead blocker and lead runner who by design are getting there ASAP. West Coast passing lives in those soft spots under and between the coverage. Air Raids attempt to warp the zones into providing bigger holes by flooding and stretching them. Option running makes a balanced coverage into an effective numbers advantage for the offense at the point of attack. Vanilla defense is made to stop whatever's thrown their way, and offenses gain success by making Mr. Jack-of-All die a consistent bleeding death.
To see vanilla defense in action throw a dart at any recording of Iowa in the last 12 years; their M.O. is to stick to this maniacally. The converse in-conference would be Michigan State. On the way home from Europe this weekend I randomly sat next to MSU LB Chris Norman. Other than "Wisconsin's offense was way tougher than any of the SEC teams," and "lol Michigan's uniforms last year," Norman happily admitted "YAARRGGH SPARTY SMASH!!" is the coaches' favorite blitz, and that they'll run it or something like it more than any other play. Some teams like paper.
So there are exceptions but the exceptions can be beat with your properly executed scissors. The point remains that all matrices aside, much about football comes down to defeating your opponent's bazooka, or vanilla thing, or "rock" defense with your rock. If you recognize this particular bit of wisdom from DeBordian philosophy, well yes in this DeBord is absolutely right. But if you don't properly mix in your constraints, and you always run rock to the same spot/guy out of the same formation, and you shuffle your fullba…uh let's not go there.
Next time (last one? I think it is but I keep stretching these): What's Our Rock?
Why so the suck against Indiana? A few things leapt out on the tape. One was YAC given up by a physical inability to be close enough to the receiver to tackle on the catch. This is the James Rogers problem, and it isn't going away. Another problem might: freshman defensive backs think "zone" means "man." BWS caught an instance of this and picture-paged Courtney Avery giving up a big gainer on third and sixteen because he dragged out of his zone.
That was an excellent example of cover three. Here Michigan will run cover two and get nailed on it. However, it's not Avery's aggressive coverage that's the problem here, it's the Michigan zone's obviousness and inflexibility.
The setup: Michigan is trying to keep Indiana out of the endzone on the final drive of the first half. IU's driven it just inside the Michigan 40 and has a second and ten. They come out in their bunch shotgun set. Michigan shows two high safeties:
At the snap four guys rush and Michigan is obviously in zone. They have JT Floyd and Mouton in the middle of the field, Courtney Avery playing in the slot, Terrence Talbott and James Rogers on the outside, and Kovacs and Gordon as deep safeties. Mouton drops into a zone to cover a potential slant and Floyd is sitting in the middle of the field about ten yards deep:
A split second later we see what's going on with this bunch at the bottom of the screen: two short routes breaking inside and out with one guy headed deeper. Rogers is essentially motionless as Avery starts moving with the interior WR:
Avery follows… Rogers is motionless…
Avery follows… Rogers still not going anywhere… IU receiver still running to the sticks… Chappell throwing…
Alert: someone done failed.
Gordon comes over to clean up:
Indiana gets a first down inside the 20.
UPDATE: duh forgot the clip.
Who's at fault here? I don't know. I don't think anyone, really. Some guesses at object lessons:
- This, like Odoms sitting way down in the hole, is a pass that takes advantage of cover two. The sideline 15-20 yards downfield is always a weak spot. Not a lot of quarterbacks can exploit that as ruthlessly as Chappell can, though in this instance it's so open a lot of QBs could make the play.
- Michigan made this read easy by showing cover two and running it. Chappell knew it was zone because Michigan just about always plays zone and did not put another guy over the bunch, and as soon as Rogers sat down on the out he knew the corner was going to be open.
- Advanced zone defenses that use pattern reading can adapt to these routes better. I'm not sure about this, but the key is that someone has to be responsible for #2 going vertical and go with him. That would be either Avery or Rogers. The other would come up on the out, leaving the drag to Floyd. Michigan doesn't do this here and probably doesn't ever do it because they've got a secondary with three sophomores, two freshmen, and positional vagabond James Rogers. Also some defensive coaches think pattern reading is suboptimal for reasons I'm not 100% clear on yet.
- Avery seems like he's in great position if this was man coverage. He also broke up a slant against BG impressively. If Michigan ever ran man I bet he'd be pretty good at it. Can they do that? Eh… maybe against teams that don't spread the field. Here I think his coverage is good given the situation and the assumption Michigan is not pattern reading.
- But it's not man and the freshman corners do this all the time. There's the BWS post with an example, and Indiana's last touchdown was Terrence Talbott in great man coverage on a slant… when he had a zone to the short side of the field that held Darius Willis and no one else once he covered the slant.
- Can Gordon do anything more here? I don't think so, but I'm asking anyone with the knowledge. Is the safety's role here tackle and live to fight another day? What if this was Reggie Nelson?
There is some good news: Michigan did adapt to this route pattern, stoning it several times late. Indiana adjusted by sending the deep WR on a post and Floyd dropped back into it, forcing Chappell to chuck it high.
Last time on Picture Pages, Denard Robinson got Roy Roundtree killed against UConn by being too impatient to throw on a curl-flat combo. This time things will go a bit better.
The setup has Michigan in a four-wide formation with ND in a two-deep shell and a 3-4 defense—this is slightly unusual since ND spent most of the day in a 4-3:
Michigan starts the play with a zone stretch fake, pulling Schilling around to act as the lead blocker Shaw was on the previous play:
Roundtree's come in like he's going to block as Odoms heads upfield:
Roundtree then breaks outside as Walls rubs Odoms, pushing him out of bounds briefly. If this was man coverage Roundtree would be open, but if it's zone it'll be Odoms, or you can also take a look at Grady running well behind the linebackers, all of whom have sucked up to either the zone stretch fake or the threat of Robinson on the edge:
It was right about here, if not earlier, that Denard threw the ball against UConn:
But as you can see from the downfield perspective, that would have been a bad idea since the corner is disconnecting from Odoms and coming upfield. If he had thrown it above, the ball would be about halfway to Roundtree right here:
This probably would have led to another decleating hit. But Denard sees the play developing and waits. A split second later Odoms sits down on a fifteen-yard hitch. He's wide open:
ND's Harrison Smith doesn't know what to do with both Grady and Odoms open in front of him. Robinson zing:
Odoms picks up some YAC…
…and it's 21 yards.
- Most of the same stuff from the last post. Michigan will see a lot of zone. Most of the routes they run will be designed to beat it. Robinson is going to be expected to high-low cover two corners a ton, not least because a hard cover two corner gives the defense much better containment on the edge than a cover three where the corners bail out into deep zones.
- Holy pants wide open receivers again. The Roundtree and Odoms catches were more spectacular and the end result of this play had nothing to do with the linebackers, but Kelvin Grady is screamingly wide open on this play too because Manti Te'o is hurtling towards the line of scrimmage and Calabrese sucked in towards the zone stretch fake. Michigan should have run more play action, though I guess it's hard to criticize what the offense did when it wasn't getting flags in its face.
- Denard is learning stuff. Obviously. I haven't gotten through everything yet and do remember a period in the fourth quarter where he was looking pretty wobbly, but the coaches probably spent a bunch of time this week working on Denard's mistakes and getting his patience right for various plays. So far there haven't been any plays against Notre Dame where I thought "that throw is way too late/early" except one on which Robinson dodged a blitzer and had his timing disrupted.
- Odoms is just fine as an outside receiver. It would be nice if he was a towering colossus of speed but given Robinson's strengths it's better to have a reliable mountain goat and experienced route-runner who can sit down in the right spots and catch the balls zinged to him. It seems clear that going over the top is not one of Robinson's strengths, at least not right now.
