Missed blocks vs. Air Force

After Saturday's game, everyone is in panic mode concerning the offensive line, myself included:

The offensive line just can't get any push upfield, which, against Air Force's undersized defensive front is a major red flag. It could be that the line is still trying to gel, but it seemed like Michigan was running power blocking techniques most of the game, which would negate many of the double teams that could cause confusion on the line.

Rewatching the game, there are a lot of different plays where Michigan's offensive line just gets beat, but there were also plays that it's clear the restructured offensive line just needs more time to play together.

On the first play of Michigan's second drive, the team comes out in a three-wide set with stacked receivers to Denard's right. Fitz Toussaint and Stephen Hopkins are flanking Denard in the backfield. The playcall is a QB lead draw.

When the ball is snapped, center Elliott Mealer gets immediately into the Air Force nose tackle. Though he'll end up being at least partially at fault for the result of this play, how quickly he gets off the ball is impressive.

After pushing the nose tackle toward Patrick Omameh, Mealer begins to release to the second level to block the Air Force linebackers. Unfortunately, he identifies the wrong linebacker to block...

....and the inside 'backer has a step on Mealer.

Not only has Mealer been beaten by the inside linebacker, but next to him, Omameh is unable to block the nose tackle (highlighted).

Air Force now has two tacklers behind the offensive line and only Hopkins available to block them.

Denard has to juke the first defender and is eventually wrapped up behind the line of scrimmage.

The Takeaway
A few things here. First, I believe this is a man-blocking scheme with a double team at the point of attack. I think Mealer is right to release to the second level so quickly--Omameh doesn't look caught off guard by the double team, but he does get beat on it--but he still fails to identify the correct linebacker to block. Regardless of who is ultimately at fault, this probably doesn't happen with David Molk at center.

The good news is that the biggest problem with this play appears to be communication/knowing the structure of the play rather than pure performance, though neither Mealer and Omameh come off looking good here. With another two weeks of practice and a cupcake game before Michigan faces Notre Dame, the offensive line will have plenty of time to watch film and get this sorted out.

The other think to watch, which isn't pertinent to the play, is Jeremy Gallon at the bottom of the screen, who bends out for a screen pass that isn't thrown. Michigan showed this motion a lot in the first two weeks but only threw the screen twice (both against Alabama, both for 8-yard gains). The Air Force defenders don't look at Gallon on this play, despite him waiting in the flat with a blocker in front of him. My hope is that eventually, this becomes a read for Denard and isn't just smoke and mirrors. If Borges is trying to use this formation/motion to draw defenders and keep the defense honest, opposing defenses actually have to react to it or Michigan will be wasting blockers who could be downfield.

Will Campbell holding

Twice against Air Force, a play ended with a holding flag. The ref turns on his mic, "Holding," Woooo, "Number 73 of the defense." I had never heard of a defensive linemen getting called for holding on a running play before and since I'm not watching the defensive tackles for potential holds, I didn't see it during the game. But it turns out, Campbell basically tackled the Air Force linemen to stop them from releasing to the second level.

On this play, the hold didn't make a difference, but I would venture to say that the Air Force coaches ask the refs to look for this before the game begins because I hadn't ever seen this called before.

That's all. I was confused in real time and assumed other people wanted to see it again as well.

Last Week
Idaho St. 21 - Air Force 49. Air Force faced off against the mighty Bengals of Idaho State last week and trounced them in typical Air Force fashion: 484 yards rushing on 58 attempts (8.3 YPC!!!). Running back Cody Getz accounted for the brunt of the load (17 carries, 218 yards, 3 TDs) while senior quarterback Connor Dietz did exactly what you expect an option QB to do (8/11 for 142 yards, 7 carries for 74 yards and 1 TD). In total, 11 different players carried the ball at least once for Air Force.

#8 Michigan 14 - #2 Alabama 41. Game recap. You know what happened here. Michigan came up against the closest thing to a juggernaut that college football will see this season. Denard struggled, the running game was non-existant, and the defense was shredded. It's been a while since Michigan was that summarily beaten, but that's what happens when you face the defending national champs and oversigning devotees.

With Air Force playing against an FCS team--especially one that was so bad last year (2-9)--last week's game doesn't give us much of an indication of how good the Falcons are. What we do know: they run a traditional 3-4 defense that was pretty soft last year. In 2011, the Falcons ranked 109th in rushing defense, 81st in pass efficiency defense, and 72nd in scoring defense.

Other than those basics, I'm not really sure what to expect from this Air Force team. I haven't had time to watch much film of them so instead of me pulling out a bunch of random stats, I'll direct you to Ace's Fee Fi Foe Film:

Air Force is woefully undersized on defense, which dictates much of what they do. Starting nose tackle Cody Miller weighs just 260 pounds and is flanked by defensive ends weighing 240 and 265 pounds each; frequently-used backup nose Nick DeJulion tips the scales at just 240, which Michigan would consider undersized for their weakside DE spot.

This results in teams running roughshod over the Falcons. Despite doing a good job of preventing big plays, they gave up 4.96 yards per carry in 2011, and Notre Dame gashed them for 266 yards on 9.6(!) ypa in their matchup last season. This is the ultimate bend-but-don't-break defense

How will Michigan fare against that kind of a defense? Probably really well. The return of Fitz Toussaint and Not Playing Alabama should help Michigan find its groove on offense. Denard and Toussaint should find lanes, and Michigan's offensive line should look much improved (including Michael Schofield, who struggled against Alabama, but will have a much easier time against the undersized Air Force).

If Michigan builds up any kind of sustainable lead (not a guarantee; see: Defense vs. Air Force), this game should be used as an open practice for Denard to get into rhythm with his receivers. Though Alabama was an experience Michigan won't face again, it was clear that Denard and his receivers have a lot of kinks to work out. We need to be careful though: it may be dangerous for the team going forward if Devin Gardner dominates a team like Air Force with shoddy mechanics. If he can't iron out his route-running and blocking issues, his utilization as the #1 receiver this year may be problematic.

Defense vs. Air Force

Via ugh

Before last week, this game seemed like a tune-up on gap responsibilities, assignment football, and tackling. In the wake of the Great Linebacker Implosion of 2012, Air Force's brand of option football looks like a daunting matchup for this defense.

You probably haven't seen Air Force play, but you may have seen Paul Johnson's Georgia Tech teams. GT and Air Force both run the wishbone offense, which has an A, B, and C back in addition to a run-first quarterback. The basic setup looks like a 5-man offensive line with two H-backs (via MGoBlog):

This is a triple option offense. The quarterback's first read is usually a dive play to the fullback. (I still have no idea who the quarterback reads here, but he's reading someone.) If the fullback dive has been taken away, the quarterback will pull the ball out and run a traditional pitch option with one of the H-backs (who pulls around the formation).

On paper, the base play in the wishbone is not all that difficult to defend, but offensive coordinators who run this system have hundreds of subtle variations on that play intended to block whatever player has been making tackles. I'll let Smart Football explain:

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.

If Michigan's linebackers weren't indecisive against the run, this would still be a fearsome offense to try to stop. Unfortunately. Defensively, this game will come down to the linebackers properly playing the pitch option, keeping the ball to the inside of the field, and reading and reacting to what the Air Force offense is doing.

As for the passing game, this seems like the kind of game that you want following an injury to your second-best cornerback (Blake Countess; Air Force rarely throws the ball more than a dozen times a game), but it's possible to see a less experienced corner getting caught cheating against the run. Though the Falcons' passing game won't intimidate Michigan's defense outright, Courtney Avery and JT Floyd will need to stay disciplined and not overreact to the option running game.

Prediction
How does Michigan win: Michigan's offense shouldn't have any problem moving the ball against an undersized Air Force defense. However, I expect the Air Force offense to put up at least 300 rushing yards against Michigan's suspect second-level defense. If Michigan is going to win this game confidently, they're going to need improved play from the linebacker corps. The defensive line will be able to take away the fullback dive all game, so playing disciplined defense on the edges is really all Michigan needs to do.

How does Air Force win: Basically, turnovers and a terrible performance from the linebackers. Denard will have to throw two or three interceptions, and Toussaint will have to put the ball on the ground for Air Force to stop the Michigan offense. On the other side of the ball, Air Force will need to break a few long runs against the defense.

Arbitrary percentage Michigan wins: 82.36%

Final Prediction: Michigan gives up a number of long runs early, and the game is relatively close going into the second half, where Denard and Co pull away. The defense eventually forces a turnover or two. Michigan doesn't cover (21 points) but still wins confidently. Air Force 17 - Michigan 35
