rock paper scissors

In this edition, Purdue recognizes that 8-in-the-box is like 9-in-the-box when the opposing offense is in 3-wide. But they're an enjuneerin' skool, so dey're smart like dat.
Wha'hoppon: Michigan has first and 10 on the 20 to open their third drive of the second half. They run a zone stretch left to Smith. Purdue slants the line against the stretch instead of flowing with it, which doesn't initially seem to do much except give Molk an easier reach block on the DT (one of several he had on the day, exactly as Brian predicted on MGoPodcast before the game). However, by slanting inside instead of maintaining outside contain, the playside DE forces Smith farther outside, where the MLB - the extra body Michigan can't quite block on this play - is headed at full speed. Purdue's paper, our rock, and Smith is stopped for no gain.
'Glass half-full' types will note that it required Purdue guessing right three different ways to stop this: 1) committing against the run with the 'extra' man, 2) slanting the DE inside instead of using him in contain, and 3) committing the MLB to the outside from the snap (although it could be argued that 2 and 3 are a combo meal). And the play was still just one ankle tackle away from being a big gain.
