That was thoroughly embarrassing. I really have no idea how the defense played so terribly. I know Ohio State's offense is by far the best Michigan has faced this year, but it's not that much better. It's not like they ran a bunch of plays that they hadn't done before. Granted, Indiana has a similar offense and showed how they could be beat, but I had confidence that they'd be prepared.
As for the offense, the running plays just didn't work, and I don't know why they still get called once that becomes painfully obvious, which it did early. The pass plays were there when called, but there were too many bad throws and catches.
Michigan probably still might've lost if they had played well, but it should've been a much more competitive game. Hopefully, Harbaugh learns from this and changes up the offense, while the defense learns how to defend better QBs. I don't know why they weren't more prepared, though.
