SITE NOTE: as is traditional during a bye week, the UFRs will be delayed a day, allowing us to ruminate in some more detail on a couple more plays that seem to be representative of larger trends.
Today in Michigan's running issues: an example of how all it takes is one breakdown for an otherwise promising play to end in the backfield. Offense and defense are opposite creatures in this regard. On defense, if you make a mistake it may or may not be punished, because someone can beat a guy and clean up for you, or the offense may not see the open receiver or cutback lane. On offense, an error is going to leave someone free and he will end your play more often than not.
A lot of Michigan's struggles so far have been one-guy breakdowns. This sounds like a promising, easy fix, but it's an unfriendly math problem. When you've got seven guys trying to execute, even if everyone has a 90% hit rate 0.9^7 is a 52% shot at someone not executing. At 95%—each guy doing their job 19 of 20 times—you still have a 30% failure rate.
That's obviously oversimplified; there are different mistakes that can make the difference between an unsuccessful run of three yards and an unsuccessful one of negative two yards. But I've been saying things like "it's just one block away from a big play" for a while now without actually seeing a lot of improvement in that category, and the previous paragraph is one of the reasons why.
Our exemplar is a zone stretch midway through the third quarter. It's first and ten after Drew Dileo extended an out route into the short seam and Gardner hit him. Michigan's in the I; UConn responds with a 3-4 look that has an extra guy hanging off the tight end side on the hash.
UConn did a lot of blitzing from the outside in this game, and this will be no exception. They'll shoot the guy on the hash upfield to be the force player and slant the other two inside, way inside in the OLB's case:
On the snap, nothing much is revealed as no one's made contact yet except Miller, who's underneath the nose tackle already:
That nose tackle is going to end up a long way downfield. I know we're all trying to take Miller's job, but he made a couple of nice blocks on these plays in the second half.
In the above shot, you can see the first steps of the defenders highlighted in the arrow picture coming inside. a half step later Michigan has both adjusted excellently and not adjusted excellently:
Both Glasgow and Lewan have adjusted their flight paths to intersect with the slanting defenders and have successfully made contact that will allow them to shove them past the play and open up a huge hole on the outside of the line, but Joe Kerridge is now trying to hit a gap that is not open.
When he does, he gets whacked.
Now off balance and a gap away from the actual hole, he's unable to block anyone. That's the one guy. When Michigan does this on defense I mention they got a two-for-one and usually good things happen afterwards.
Here bad things happen because Yawin Smallwood is now hanging out in the hole unblocked.
Fitz compounds matters by seeing this, considering a bounce, and then deciding against it, which gives up a couple yards.
Second and twelve blues.
Items Of Interest
Well, poop. Michigan blocks this really well on the line, getting both slanters sealed inside and driving the nose tackle back into a linebacker. But once Kerridge gets picked off, this play has a maximum reasonable expectation of about one yard. It only takes one error.
This would take some pretty fast recognition to fix. A lot of zone teams either eschew lead backs or place them in positions such that they, too, have a long path to the hole (think about "superbacks" in spread offenses that start lined up next to the QB). Kerridge is lined up to the playside about three yards in front of Toussaint and his first steps are upfield as he tries to build momentum for a bone-rattling LB block. Toussaint, in contrast, kind of waits and runs lateral to the LOS for a bit, so he has time to see the slant develop and find the hole that is unfortunately filled with one Yawin Smallwood.
Kerridge doesn't have that time. If he's going to make that read presnap he's probably guessing that the OLB is going to attack the gap outside of Lewan, and when that turns out to be wrong he's already committed. I'm not sure he can be any other way when he's lined up so close to the point of attack.
If you're going to do this it almost seems like you'd have to consider Kerridge another lineman and that Lewan should release downfield into Smallwood once the OLB crosses his face, but holy hell is that complicated. Michigan should be trying to make everything as dead simple as possible so they can have uninspiring runs that do pick up some yards.*
So this is a rock paper scissors minus. I don't think Kerridge has time to change his gap, and that gap gets filled by a slant. Even if Kerridge 1) has the option to pick his hole, 2) made a presnap read of the blitzer, and 3) assumed the OLB would slant inside, the OLB is outside of Williams so a one-gap slant takes him outside of Lewan. This puts Kerridge in the right hole. When the OLB goes two gaps over that's when the problems happen.
Toussaint bounce attempt again. Like that Nix play discussed earlier, here Toussaint has grim prospects that he makes a little grimmer by trying to escape. Despite all your rage, Fitz, you're still just a rat in a cage. Here it seems like he has been told that he needs to go N/S and remembers that after his natural inclination. Or he just thinks he can't get outside Williams. Whichever.
It is not an easy decision to bench Jack Miller. The entire world has already benched the guy for the Minnesota game; I'm 50-50 on that. I'm frustrated with him sometimes as well, but here's another loss on which the offensive line appears to be working just fine. He got dumped into the backfield once earlier in this game and struggled in a couple of pass protections (a couple of other pressures that came up the middle were not on him), but I wouldn't be surprised if Michigan soldiers on with their current five guys. Even if they don't, how long is Chris Bryant going to be able to stay on the field?
Also, folks speculating that Michigan might move Michael Schofield back to guard and insert Braden or Magnuson should stop. Miller is not bad enough that switching three spots on the OL and sending a good right tackle back to guard so you can insert a freshman is anywhere near an upgrade. That's a midseason switch worthy of a Rodriguez defense.
*[This is iso's role in the world. It is the DURRR SMASH of run plays, requiring almost nothing other than brute strength and rarely picking up more than three yards, but rarely losing any.]
