This is just pure aaargh right here, but how about a preview of why the Michigan defense was so terrible against UMass?
It's first and ten on the Michigan 35 on what will be UMass's second touchdown drive. UMass comes out in an ace set with two tight ends to the short side of the field:
Michigan is in a 3-3-5, basically, but the twins formation and the double TEs distort it. Roh's off the field momentarily, replaced by JB Fitzgerald. UMass is going to run it up the gut:
There's no pull on this so it's an inside zone. There's nowhere to go with RVB shoving his guy into the backfield, Kovacs beating the second TE to the inside, and Leach blitzing unmolested off the weak side. Michigan has basically killed this play as the RB has no choice but to head outside, where…
…Mouton is totally unblocked. You can also see Kovacs poking his head through at the top of the line and Van Bergen getting his shove on.
Anway, Mouton: with no one outside of him because of the alignment he's the force defender who must get the tailback inside of him, where Leach and a scraping Ezeh can deal with the tailback if he cuts back inside tackle. (For some reason, this is "keeping leverage on the football.") And he's playing against a I-AA tailback. So he runs up real fast…
…lets the tailback outside of him…
…and personally turns zero yards…
Seriously, there's nothing else here except Mouton making an enormous mistake. The good news is that if they fix that stuff the scheme of the defense is fine. It's not like they're asking the players to do anything particularly difficult or novel: make tackle. If cannot make tackle, funnel RB to help. Do not let RB outside of you. This has nothing to do with a shift to a 3-3-5. Look, here's Mouton doing the pretty much the same thing last year, albeit against a blocker:
That's the bad news: if these linebackers have been starting for three years and are still making these mistakes, why would they stop now? GERG linebacker fairy theory is about it and that took a major hit against UMass.
Maybe it was just an off day, one on which the linebackers took it easy and reverted to old, bad habits. Yeah. That, too, is the ticket.
