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.

A few weeks ago I promised to finish this piece on the differences for Michigan's personnel in the 4-3 over. Sorry.
Refresher: What's a 4-3 Over? What you're looking at are alignments of the front seven. The "under" shifts the defensive line away from the strength of the defense and the linebackers swing the opposite way to compensate. Michigan would often align this to the hash rather than the offense, shifting the DL toward the sideline.
The "over" shifts the line the opposite way, but not to such an extreme. The linebackers wind up centered over the ball, and the DL spread across the formation. There is nothing 3-4 about it except the nose tackle.
Last time I talked about how going from a base under to a base over will demand the WDE and 3-tech play a little bigger, the SDE can play more like a rush end, and the nose's job stays pretty much the same except he's now the backside DT. Now on to the second level.
Strongside Linebacker (SAM): James Ross/Royce Jenkins-Stone
The 4-3 under is tough to run against—often they wind up blocking the backside DE in hopes of getting something from a cutback, since it's hard for the LT to get to anybody else. That meant the WLB could be a free hitter
On inside zone that strongside (right) tackle is trying to get a free release. The 3-tech could get aggressive and slow him up but the danger of playing aggressively on the DL against a zone running team is you open up the backside. The faster the OT gets out to the second level the more room there's going to be for the running back to dodge around the DT. A SAM who can read IZ quickly will be all up in that OT's face, able to affect both frontside gaps without opening up the backside cut. Every half-second of delay on the SAM's part is another yard for the offense.
But the SAM can't get crazy-aggressive attacking the OT or the C gap because that tight end is an eligible receiver, and there's another receiver on that side of the formation who could be slanting or dragging. Since the guess is Michigan wants Jake Ryan to be aggressive in the middle, Ross will end up in a lot of zone drops or in man-to-man on the tight end.
The fit: The WLB in the 4-3 under that James Ross played last year isn't hugely different, but it wound up playing differently because Ross was constantly having to take on blockers thanks to Michigan's Jibreel-Black-is-a-NT stunt-a-thon. His quick-twitch reads will be an asset, and his speed and coverage ability will be also. Michigan State's defense had Denicos Allen blitz a ton from this position, and got away with it because the handsy press coverage took care of the slant/drag passes that punish it, and because they had Max Bullough to read and react at MLB. Ross will get to blitz more than he did as the backside linebacker, but I'm guessing Michigan would rather he be the read-react-hit-spill dude so Jake Ryan can go viking.
[jump for the other two spots]
This here Friday because not enough for Dear Diary.
What do you think of the transition to a 4-3 over? Who else is running it? Is it so much of a shift?
Ace: While I was skeptical at first—it felt like a bit like a panic move—I've started talking myself into this being a positive change. The main reason is that it should allow Michigan to generate more of a pass rush, and in less predictable ways. Seth pointed out the benefits for both Frank Clark and Brennen Beyer in his post—they slide into roles more suited to their abilities in a way that gets them on the field at the same time. Add in the ever-present threat of Jake Ryan blitzing up the middle and I think the pass-rush will be improved thanks to this switch.
|When you have Clark and Beyer (and Ojemudia and Taco etc.) available this isn't the best use of Jake Ryan [Fuller]|
The defense should also be better suited to go against spread attacks by keeping Ryan in the middle. He no longer has to worry about playing over slot receivers or being the primary defender against bubble screens, and when Michigan goes to a nickel, they'll most likely lift James Ross for a defensive back—adding coverage without losing much from the pass rush.
Keeping the linebackers clean against the run is also easier in a 4-3 over; Iowa's linebackers were very successful last year in part because their alignment allowed them to roam free sideline-to-sideline—I was dumb enough to confuse "DTs aren't making plays" for "DTs not doing their job" in that post, when it turned out Carl Davis and Louis Trinca-Passat were really good at holding up against double teams while the Hitchens/Morris/Kirksey trio combined for 35.5 TFLs despite rarely blitzing. I highly doubt Greg Mattison's defense will be as passive as Iowa's, but the Hawkeyes still provide a solid blueprint for how to get better production from the linebackers.
That brings me to my biggest concern, however, which is the defensive tackles. I believe the Henry/Pipkins combo will hold up fine at the nose, but the lack of experience at 3-tech is worrisome. The good news is both Chris Wormley and Matt Godin—the likely rotation there, along with Ryan Glasgow—were tweener DE/DT recruits with large frames, solid strength at the point of attack, and some concern about their edge-rushing ability; the last part matters much less now, and as long as they're not ceding ground with regularity, the experienced linebackers should be able to work behind them (Northwestern's linebackers managed to stand out in their 4-3 over even though their DTs routinely let the seas part).
My other main concern is how Ryan will handle more offensive linemen releasing to block him at the second level, but I have the feeling he'll figure it out. It's clear the coaches have been planning this shift for a while—see: Noah Furbush, MLB recruit—and despite a few minor bumps along the road I still have a great deal of trust in Mattison. If, as advertised, this shift allows the defense to be more aggressive in general and more adaptable against spread attacks specifically, I'm on board.
[Jump: Brian and BiSB go over this more. HA!]
In honor of our annual right there -----> which I expect will get Kickstarted a third year in a row today, I thought I'd share a little sneak peak from it. Brian asked me to create these for the linebackers page:
Click to big. Right-click to open in a separate window so you can reference it as you go.
That's a side by side comparison of Michigan's prohibitive starters this year before and after the "shift" to a 4-3 over and accompanying position changes were announced. Seeing it you can start to appreciate how all of those announcements make sense.
For the lay, what you're looking at are alignments of the front seven. The "under" shifts the defensive line away from the strength of the defense and the linebackers swing the opposite way to compensate. The result is very much like a 3-4 (picture the WDE in the photo above as yellow) and plays like it. In this alignment the strong side is the left because there's a TE there. Michigan would often align this to the hash rather than the offense, shifting the DL toward the sideline.
The "over" shifts the line the opposite way, but not to such an extreme. The linebackers wind up centered over the ball, and the DL spread across the formation. There is nothing 3-4 about it except the nose tackle.
Let's run through the positions to appreciate what's changed and what will be expected of them.
Weakside Defensive End (Frank Clark/Mario Ojemudia)
Ojemudia lined up as a 7-tech in the under [Fuller]
In the Under: The WDE is the leading pass rusher. He lines up so far outside of the backside offensive tackle that he'll wind up getting a 1-on-1 battle with that guy all day. The tradeoff was being further from the point of a attack in the run game. The WDE is further from the run game but in position to drop into coverage, a thing he was tasked to do quite often as the DE-like linebacker opposite him charged into the backfield. Much of the good done by the over shift is it creates double teams elsewhere to preserve the WDE's ability to attack upfield.
In the Over: The weakside end is still outside the offensive tackle, but shaded in a "5 technique," i.e. over the outside shoulder of the offensive tackle.
If you remember your 5-techs from 4-3 under school, you'll get the difference, though unlike your Ryan Van Bergens the weakside end usually doesn't have a tight end lined up to his side (ace even, H-backs and the like do happen) so he needn't be a double-team-eating anchor. The new WDE's biggest change is he's not dropping into coverage all the time. He has to control that OT in the run game, and often he has to cover the B gap. The linebackerity of the position has been removed; this man is a defensive lineman, and not necessarily a flashy one—Michigan State's been plugging their workhorse DE Marcus Rush in this spot for four years while various SDEs make the highlight reels.
The fit: Clark showed signs of being a pretty good player by the latter half of last season and now up near 260 he is large enough to not get kicked by OTs. As a pass rusher he's only like fifth or sixth in the conference, partly because the interior DL couldn't push the pocket very often, and partly because he wasn't great at closing when he beat his guy. Ojemudia and true freshman Lawrence Marshall aren't large men in your memory, but both claim to be up to 250 now. They're all better full-time defensive ends than 3-4 OLBs.
[Jump for the rest of the DL—LBs coming up in Part II]
ROTATE [Bryan Fuller]
Per first spring presser:
James Ross and Royce Jenkins-Stone to SAM. Probably inevitable once Ryan move was announced. Obviously Michigan thinking more along the lines of the Stevie Brown style LB/S hybrid there, as Allen Gant is your other SAM at the moment.
And with this shift comes another:
Hoke said will run more Over defense as opposed to Under.
— Matt Pargoff (@MaizeBlueNews) February 25, 2014
That means the line shifts towards the tight end and the linebackers away. Instead of this:
Last year 5 was Clark, 3 Black, 1 Washington/Pipkins, 5 Heitzman/Beyer, LB Ryan, W Ross, M Morgan.
Michigan will run more of this:
Upshot is the MLB gets significantly more protection, the WLB has to be able to take on more blocks (everyone has to take on blocks) and the SAM can be a lighter player as long as the three-tech and SDE create trouble when single-teamed.
This is a significant change, as you can see by everyone flopping about on the depth charts. While it's not switching to a 3-3-5 and back six times in three years, it does signal uncertainty.
A move to the over does make the Ryan move make a bit more sense but either DE spot is probably a better location for him unless he's suddenly a savant.
Heitzman to TE. With Henry seemingly locking down three-tech that potentially bounces out one of Strobel/Wormley/Godin to SDE, where Brennen Beyer is probably your starter anyway. Heitzman gives Michigan a shot at blocking someone, anyone, and won't be missed.
This would be a good time to remind you that Hoke told the gathered folks at the Detroit Athletic Club that Jake Butt would be back by game three; even if that's a weirdly specific prediction this far out given Jake Ryan's recovery timeine that would be about right.
Shallman to H-back. He wasn't already at H-back?
Ross Douglas to RB. Supposedly had been running there on the scout team and impressing. Michigan does need another bullet there with the loss of Rawls and Toussaint and no recruits filling in the gaps, and meanwhile Ross was at best sixth on the CB depth chart. Kind of doubt he makes much impact this year with Hayes presumably a lot like him and more experienced.
David Dawson to (left) tackle. I'd been telling people Dawson was likely to be the G/T tweener thrust outside by a lack of depth, but even I thought he'd be assigned right tackle duties since he's 6'4". Nope. According to Hoke, the current and incredibly nominal first team line reads Dawson-Bosch-Glasgow-Kalis-Braden.
Erik Magnuson is all but certain to side into that LT spot when he returns, leaving Bosch and Dawson to duke it out on the right. You can read Dawson on the left as an endorsement since that's the most important spot, or you can read Braden on the right as an endorsement since they may expect him to start and want to get him settled in at the position he'll play.
The other guy to watch out for is Patrick Kugler, who could bounce Glasgow out to one of the guard spots and give Michigan some depth.
Logan Tuley-Tillman is out right now, FWIW.
The 4-3 is back, like it never sort of left and then really really left against Purdue and then came back and then altered into a slightly different version of itself and then mutated into a bizarre thing that was like the thing against Purdue but wasn't really because the person doing the mutating spent all his time watching his "Best of Just For Men Commercials" DVD. It will not suddenly be replaced by things that start with the number 3 and end with razorblades and pain. In the long term, this is delightful.
In the short term… eh… there might be some issues. This series is an attempt to fit Michigan's noses, ends, spurs, bandits, spinners, deathbackers, doombackers, dipbackers and frosting-covered gnomes into their new homes.
We start with the defensive line.
What we were forced to watch last year
Michigan stemmed into four man fronts occasionally but spent most of its time with a three man front featuring a traditional nose tackle who lined up directly over the center and two defensive ends. It was unclear to me if these defensive ends were intended to slant one way or the other at the snap—an aggressive "one gap" system—or if they were reading and reacting—a "two gap" system—because of the massive confusion surrounding them. It was hard to tell if Greg Banks was trying to cover two gaps unsuccessfully or just getting single blocked all the time.
They did typically line up slightly outside (lingo: "shaded outside") the tackles, indicating that it was probably the former:
You'd have to be the sort of idiot that would have Craig Roh play linebacker to play Craig Roh as a two-gap DE at 235 pounds, but… yeah.
At other times Michigan would switch to a four-man front in which their linebackers did things that made no goddamn sense at all, like on this soon-to-be 61-yard-touchdown…
…but that's another show. I bring it up to point out that in this situation you see Greg Banks as the weakside(!) defensive end, Craig Roh as the strongside guy, and Ryan Van Bergen folded inside to be the three-tech defensive tackle. This is a shifted line rather than an 'even' line, but more about that later.
What we were forced to watch the year before
Michigan ran mostly four-man lines and while they varied they usually put Brandon Graham on the weakside-ish of the formation. Here Illinois presents a balanced line with two TEs but you can see Martin lined up over the nose tackle and Graham to the bottom of the screen with a big gap between the two. Banks and Roh are to the top of the screen:
The linebacker walks down to the LOS in an effort to prevent Graham and Martin from getting double-teamed. When there is no TE on the weakside teams had a choice between singling Graham or Martin, which is why Graham got to eat the universe so often.
Sometimes they would line up differently. Here's another play on which Graham is on the weakside, well outside of the tackle as Martin lines up directly over the guard:
This is actually an "even" look where Michigan's not shifted. The DTs are over the guards, the ends line up outside the shoulder of the tackles.
They did occasionally stem into 3-3-5-ish looks, but note here that the defensive "ends" are lined up inside the tackles—this defense is designed to push runs to the outside.
Michigan ran this front most of the day against Ohio State and had success against their traditional I-form game, but struggled when the Buckeyes went to unbalanced spread sets. USC ran this quite a bit in the last few years of the Carroll regime; they called it "double eagle".
What can't possibly be quite as bad next year
My assumption is the defense is going to look a lot like the 2009 one did. That was a 4-3 under. I was going to go dig up old Michigan rosters featuring the "rush linebacker" to demonstrate that Michigan's old school defense also tended to have a guy hanging out on the edge made of menace and sacks while the other guy enjoyed fighting off tight ends but then I remembered Hoke obviated the need for circumstantial evidence:
“We’re going to be a four-three defense, either an over or under front.”
Those sound like two totally different things but they're not. This from above is an "over" front:
This is an "under" front:
And you're probably like "that's the same damn thing except Craig Roh is standing up." You're right. The difference in the pictures is the offense. In the MSU still there are more DL to the side with the TE and FB; in the Western still there are more DL away from the side of the formation with more dudes. Both have a one-technique DT and a three-technique DT. Both leave a big gap between the one-tech DT and the DT to his side. They're just mirror images of each other. A couple of helpful graphs from Shakin' The Southland to clarify. Michigan's overshifted line in the State image:
And the undershifted line against WMU:
The only player that ends up aligning differently is the strongside DE; it's really just flipping the tackles over.
That's still a useful distinction Hoke made for us, though, because a team that is under/over is going to have different requirements than a team that aligns even like Michigan did on that Iowa play above. We get to keep our terminology from two years ago when we talked about the three-tech DT and the one-tech DT.
Every team is "multiple" these days and will run under/over/even fronts as changeups. Also, the generally accepted theory is that under is better against pro-style teams that will bang your head and over is better against spread teams that will take your strongside linebacker into the slot. So when Hoke says "under/over" he probably means Michigan is going to run both depending on situation, not that they'll pick one when they figure out their personnel a bit better.
What you need at each spot
From right to left in the second graph above:
- The weakside defensive end is going to get a one-on-one matchup with the tackle most of the time and needs to turn that opportunity into plays. Think Shawn Crable, Pierre Woods, etc.
- The three-tech DT also usually gets a one-on-one matchup with the guard. He should be a penetrator that gets into the backfield with regularity. NFL DTs you've heard of (Warren Sapp is the canonical one) who aren't barely mobile piles of goo are probably three-techs.
- The one-tech DT is going to experience a ton of double teams as the offense attempts to attack the "bubble" in the front the defense leaves but not putting someone over the other guard. You know all those successful zone running plays the site has explained over the years that start with a guard blocking some DT and end with that guard plugging a linebacker as someone else slides over to finish the job on the NT? That's what you don't want your nose tackle giving up.
- The strongside DE should be Brandon Graham. Failing that, he should be a big, strong guy who's good against the run and can add some pass rush here and there.
A post from Battle Red Blog provides more detail on what your 4-3 under requires—at least on an NFL level—if you're interested.
Who goes where
Craig Roh is the weakside defensive end and will be backed up by Herron/Paskorz/Beyer/Heitzman. Attempts to move Roh elsewhere will be thwarted by a plucky band of kids and their dog ripping the Mattison mask off of a dastardly Greg Robinson.
There are two scenarios for the rest of the line. In the happy fairy dance scenario, Mattison, Hoke, and Beyonce are so much better than Bruce Tall and Greg Robinson that they transform the platoon of Will Campbell, Quinton Washington, and Richard Ash into a functional one-tech DT. Here's what happens if they don't and they move Martin:
Yeeargh. I'll believe Will Campbell can play D when I see it but Ash and Washington got some praise last year so you've got three bullets. It's possible this happens, if not probable.
If you can assemble a frankentackle in the middle then you can slide Mike Martin out to the three-tech spot he doesn't know he's been coveting for years. Imagine senior Martin getting single blocked on most plays. Tingling is normal when contemplating this scenario.
As a bonus, successfully moving Martin to the three tech allows you to leave Ryan Van Bergen at DE, where he is the kind of solid run defender you need on the strongside. He'll chip in a half-dozen sacks and be the B+ version of a strongside defensive end and that will be fine.
The realistic-thing-that-will-be-called-pessimistic-in-the-comments scenario is that Campbell/Washington/Ash produce a guy or two worth platooning but actually running those guys out as starters is asking to be smashed. This strands Mike Martin at the one-tech and essentially forces them to move Van Bergen back to the three-tech spot he occupied in 2009. Redshirt freshman Terrance Talbott is the only other three-tech on the roster until fall. Neither of these things are necessarily bad. RVB graded out decently in UFRs a couple years ago and picked up six sacks; Martin is good enough to play either spot.
What is bad is what that does to the strongside defensive end spot, where Jibreel Black would be an all-but-certain starter as a true sophomore. Black had some promising moments last year… as a pass rusher. He had many more in which his terrible run defense hurt Michigan, and while he'll get better it seems doubtful he'll get better fast enough to be an asset. The only other option at SDE is redshirt freshman Ken Wilkins.
It is possible that in this scenario they put Roh on the strongside since he'll be a junior and he's been less prone to crippling mistakes against the run. His main problem has been a lack of size that the offseason should come close to erasing. That would take a guy who's presumably going to be Michigan's best pass rusher and put him in a position to get doubled lots, though.
Awkwardness Rating On A One To Rodriguez-Interviews-Hoke Scale
Depends on scenario but this shouldn't be too bad. In the happy fairy scenario Michigan's personnel fits a shifted line like a glove. You've got three battleship type NTs, two guys on the weakside who will wreak havoc, a solid guy at SDE, and a scattering of decent backups.
Even in the regular non-fairy scenario you've got good personnel at three spots. SDE would probably be an issue. Either way it's way better than trying to use Craig Roh as a LB or three-man-line DE.
