Last time on keeping Michigan's overtime record sterling, Will Campbell played both sides of a guy and turned second and three into third and one. Venric Mark gets dinged on that play, Mike Trumpy comes in, and it's time for third and short.
Northwestern comes out in a goal-line version of the pistol they just ran. They again flip the FB:
Michigan sets up in an over front, which was unusually prevalent for the second straight week. It won't matter much because this is going to be a pass, which third and one with Kain Colter and you throw—Michigan's defense puts the fear of God into you on short yardage.
Michigan sends James Ross; Gordon and Floyd back out into coverage. Both NW players are taken care of, leaving only the tight end on the backside, who is running a slant to the interior.
This is not Demens's guy, it's Taylor's. Michigan is in man, which you can tell because of this:
The instant Mark lowers his head to block Ross, Demens starts flying at the LOS. He's got the RB out of the backfield, and once that RB commits to a blitzer he is now in QB attack mode.
Here's a wider shot:
Demens is moving before Colter even completes his drop. By the time Colter has taken a single step, Demens is across the LOS and closing:
It's now fourth and the game.
Things And Stuff
Colter had the third guy in the pattern but did not have the patience. He decides to take off after seeing the first two reads covered. Demens's presence may dissuade him from trying the route, but that TE is well inside Taylor and Ryan if Colter waits another beat or two for Demens to fly up at him.
Those guys were pointing at each other before the snap, confused; I am not sure if it's on Ryan or Taylor. Either way those guys are going to have a little trouble covering this since they're both lined up outside of him.
Can't really blame Colter for going one-two-go in this situation, but it looks like Michigan was banking on that being the default reaction here given how aggressively Demens plays this. He was likely told that if the back stays in go get the QB. If it's third and five, maybe he waits for Colter to take off.
Ross and Washington give Demens the space. Washington's playing this like he would a goal line carry, submarining the OL with no other thought than moving the LOS backwards. Look at that still above: mission accomplished. Ross meanwhile has bashed the OL he blitzed into into that mess and is taking the Mark cut block. Colter is looking at two guys against one blocker, who is Venric Mark, and knows those odds—another reason he was all GTFO.
