We've been throwing around a term for how Michigan is playing defense this year a lot lately and haven't stopped to explain what it means: Playing to Spill.
Definition
Playing to spill is a defensive technique where the force player (edge defender) dives inside of a kickout block while another defender pops outside. This is done on the fly, usually against power runs, as a way to screw up blocking assignments and force the ballcarrier into this now-unblocked outside defender.
A play
So Maryland—not for the reason you might think—runs an offense extremely similar to Michigan's. Particularly this week they were heavy into arc zone read and its counter, split zone, plus pin and pull and its flipside, Counter Trey. We've discussed Counter Trey on here a bunch. It's Pin & Pull the opposite direction with some counter action in the backfield to get the defense stepping to the frontside before you swing the ballcarrier and a few escorts to the backside.
Locksley's Terps will kindly demonstrate this for us:
This is vintage Locksley: trying to get you thinking about a run one way so you're not paying attention when it goes the other way, then he thunks your edge guy outside, pins you inside, and rips somebody's heart out. On this play you see the tight end come across the formation and the running back step that way like it's going to be that edge pitch Penn State liked to run, and it's a surprise when the ball goes the other direction. Michigan's defense wasn't fooled however.
Remember, the pulling guard coming across the formation is trying to kick out Aiden Hutchinson, DE #97 on the top of the line. I want you to pay close attention to Aiden's response to the kickout. The pulling guard wants Aiden standing outside all passively. Aiden has other plans; he sees the guard coming…
…and leaps inside of him:
Aiden has now placed himself in the intended running lane. But this is Maryland's most base play, and the guard doing the kicking knows how to respond to this: turn the end inside. If you recall Michigan was doing the same thing on their pin & pulls versus Illinois.
The difference is here Michigan's defense has an edge.
