It's Air Force's first possession of the second half and Denard has already run 58 yards down the field for a touchdown. The Falcons have driven the ball to the one yard line but Michigan has forced a fourth and goal. On the previous play, Air Force tried a QB sneak that failed miserably, so Mattison has called for defensive linemen to cover the Air Force center and guards.
Before the snap, the Air Force H-back motions to the strongside of the play.
When the ball is snapped, the H-back continues around the formation, but the running back begins in the other direction. This will be a pitch play to the running back.
Raymon Taylor, Michigan's outside defender--the guy responsible for not letting anyone outside of the defense--unfortunately heads straight for the ball and cuts underneath the Air Force receiver who is happy to oblige Taylor the lane knowing the play is going outside.
The receiver helps Taylor along (this screen makes it look like a block in the back, but it probably isn't). The Falcons' left tackle is also cutting Thomas Gordon (#30) to the ground.
Taylor supermans for the tackle and misses hilariously.
And without outside defenders, a field of daisies.
If Michigan lost this game, you can be sure I'd be irate about this play. But they won, so, wheeeee.
Taylor is young and it's good that this happened against a team that Michigan beat instead of a loss in which this could have been the turning point. You can be sure that Mattison and Hoke sat Taylor down in the film room and showed him this play a few different times to explain that as the outer-most defender, it is his responsibility to keep everything on the inside of the defense. We'll see if he's a quick learner, but this is a pretty obvious example/mistake to learn from.
