I was just thinking about this. Rudolph scored with 3:41 left on the clock. If he hadn't scored but instead got tackled at lets say they're 35(still a good gain) or even dropped it they would have had a lot of time to drive down the field. I'm not sure if our defense could have stopped them but lets assume they couldn't. They then would have scored giving us much less time. IF they took 2 more minutes to complete their drive, we would have only had a minute and a half to score. This is all assuming that they could drive on us, but i am led to believe that between Floyd and rudolph they would somehow come up with some amazing catches and a solid drive. So as much as it pains me to say it, I almost believe that getting scored on so fast was good for us, since we got so much time to make our drive. And with our run oriented offense, we need a decent amount of time so that we don't have to primarily pass.
The nutty Michigan coverage isn't so much about Harbaugh as it is a signal to the Big Ten that Fox wants to party.
