to play football, not to play trumpet
Okay, so. On the last play Michigan picked up three yards when Brandon Minor cut behind Steve Schilling and got tracked down by the backside defensive end.
On this play Michigan returns to a more conventional formation. They're going to run the exact same play:
Again, the key block on this is the Schilling-Moosman double on the playside DT. Getting him blocked and Moosman into the linebackers is win.
Okay, Moosman has engaged with the backside DT and is actually driving him back off the LOS a bit. He didn't get this much push on the last play. Schilling, also given the humiliatingly amateurish Paint Arrow, is hustling to get into position.
Schilling's still rushing to get there, but on this scoop we see Moosman already disengaging to get to the second level… look at him facing downfield, not towards the guy he's nominally blocking. You can see Schilling's knees buckle.
Schilling intends to cut the DT. For this to be legal, Moosman can no longer be engaged with him; this block requires precise timing.
Moosman is away, again with great angle to block a Purdue linebacker who's got no idea what's going on. You can see the frontside DT shooting hard to the playside. There is about to be…
…one hell of a crease. Minor cuts up. Note that the linebacker Moosman had such a great angle on has decided to go around the other way. The backside DE is still chasing, but Minor's cut isn't taking him back to the right enough to be caught.
Minor bursts into the secondary for 21 yards. The backside DT, nearest to you in the picture, is still getting up. That linebacker who eschewed contact is waving at Minor's legs as he passes.
Object lesson on this one is: cutting a defensive tackle to the ground is a good idea, if you can do it.
Also, it is sad that Michigan's running game commands so little respect that Purdue has six guys in the box on second and seven. Four wide and all that, I guess, but still.
