Ed. Read The New Defense (Part 1) before reading this.
This isn't much different than the play I broke down in The New Defense (Part 1), in fact, it's the exact same defense and the exact same offensive play call. But the result is a little different. And that's encouraging.
You can see on film at the end of The New Defense (Part 1) that Greg Robinson grabs Williams after the play and gives him a very specific directive. I assume that this is exactly what he told him. Ezeh and Mouton should be able to give chase if it ends up as a run play, and Williams crashing on that short zone should limit or take away these short passes. Again, empirical improvement in game. This is encouraging.
The one problem with this defense, as you might guess, is that it takes arguably our best defensive player (Warren) and mostly neutralizes him. I think the positives and negatives balance out in the end, though. This alignment makes it difficult for Michigan to get beaten on the long ball while, if everyone plays their respective zones correctly, also takes away the short passes. The 4-4 alignment also helps with run defense and puts a lot of players in the box--there's actually a really good breakdown of a similar defensive play call over at Trojan Football Analysis. There are obviously flaws here and Michigan is going to need to work on a few things, but this is mostly encouraging.
The final part of the series will be coming around Noon.
