short yardage defense

wsg Slanty, the football-playing, jean-vested gecko who is inexplicably the first hit in Google images for "line slant football", or at least was a year ago.

One of my main concerns going into the season was what would happen to the short-yardage defense that Michigan was so good in a year ago without Mike Martin and RVB. Turning a third and short into a punt is 50% of a turnover, and Michigan could paper over a lot of deficiencies last year by telling Mike Martin to destroy some guys on third and one, thus allowing other guys to tackle.

Illinois disclaimers are in full effect—they can't do anything against anyone—but the Illini could do even less of anything against Michigan Saturday, and getting bombed on short yardage was a major part of that.

Michigan blew up Illinois short yardage with slants. Multiple times we saw this pattern:

1. Michigan slants away from a power run.
2. The playside end gets inside and upfield of the tackle or end trying to block down on him.
3. The pulling guard bangs into the playside end.
4. Linebackers profit.

Actually, Michigan doesn't so much "slant away" as show one defense and run another. When Michigan isn't running their base 4-3 under call they are inverting it by blitzing Ryan and moving everyone else over a gap.

Let's see it in action. /fishduck'd

It's fourth and one on the second and final Illini drive to make it past midfield, just before the half. Michigan has just stoned a power run by Riley O'Toole for a half yard to set up this opportunity. Illinois comes out in one of their standard sets, a pistol with two tight ends to one side of the line and twinned WRs.

Michigan is in an over this time since the strength is to the boundary, but Illinois will move a tight end over and not have an unbalanced strength on the line on the snap anyway so whatever.

This is what Michigan does:

They're essentially moving everyone over a a gap and dropping Ojemudia into a short zone. On run plays he "folds" which consists of backing off, keep an eye out for cutbacks, and allowing the linebackers to run to the frontside. If you're watching a replay and are wondering if Michigan's doing this gap-shift thing, the WDE backing off the LOS is a sure tip. If you watch for it, you will find it—Michigan runs this on upwards of 20% of downs.

On the snap, Ojemudia backs off and the line shoots down. Gordon, who is right behind Ojemudia in the above frame, has followed the TE across the field and now takes contain responsibility to the playside.

You can see the slant better from this angle:

Campbell is now attacking outside the left tackle, like he's a WDE. Roh and Ryan both shoot gaps to the inside. They get penetration, giving up an outside crease to do so.

Ryan gets under fast. He's essentially through clean, so the pulling G has no choice but to pick him off. Demens is already a yard off the LOS and charging as the handoff is made.

Now it's all about tackling.

Check.

Demens went inside out here as the back tried to go north and south on fourth and inches. That allows him to use the pile as help, and look at Desmond Morgan popping up to say hi/clean up any messes.

If you take a second look at this frame:

Note how Morgan is also clean and has stepped playside as the slant develops. He's still trying to check for any potential cutbacks and find the gap he's going to fill; he is available if the back makes Demens miss or threatens to power to the line.

1. Is the defensive line going to survive?

Son of a bitch. I told you not to ask that. I don't know, man. I don't know.

On the face of things it's not completely dire. Michigan starts two seniors and two juniors. They're big. The backups aren't freshmen, for the most part, and when Michigan's in the nickel package they'll lift the dodgiest parts of the line for what promises to be a stunting, slanting, pressuring Ryan-Roh-Black-Beyer/Clark group. The starters are all touted recruits save Black. Meanwhile, Michigan has three DL coaches and coached Will Heininger up like whoah last year. BONUS: If you squint it kind of looks like "QWash" looks like "quash."

They're unproven, and the lack of playing time last year is a cautionary note. Defensive linemen rotate, and rotate a lot if their coaches have faith in them. Washington hardly existed last year. Campbell did, though, and to a lesser extent so did Black.

A potential problem is the swing in strategy Michigan has to undertake as they transition away from the best penetrating nose tackle at Michigan since NTs ballooned into the 300 pound range. Quinton Washington may turn out all right; he's not going to be Mike Martin. This means the linebackers have to take big steps forward, beat guys who are (hopefully) releasing late after Washington and Campbell shove them back, and fill impeccably. The linebackers' jobs should actually get easier since Michigan has a pair of guys who can demand doubles (hypothetically); they'll have to make a quantum leap in consistency if the rushing defense is going to tread water.

Add to that a non-nickel line that looks like it's not going to get anywhere near the quarterback and you've got a recipe for frustration, or at least a lot of bending as Kovacs and company make tackles to extend drives and the front four tries to put opponents in passing downs.

Verdict: meh, but no worse.
