There isn't much you can say here. Michigan is a bad team this year. If we don't beat them now we never will.
Defensively they are pretty respectable but far from great. The defensive line is impressive as their rushing defense numbers indicate. But the secondary is vulnerable and teams like Utah, Notre Dame, and Toledo were able to take advantage of that.
Offensively there isn't much to be scared about with Michigan. Take Sam McGuffie out of the game and you have neutralized half their offense. Odoms and Mathews are wide receivers with potential, but they have quarterbacks that struggle with accuracy and decision making skills. Whether it's Threet or Sheridan there isn't much to be scared of from the quarterback position.
The one aspect of Michigan's game that is going to make life difficult for us will be the punting of Zoltan Mesko - Space Emperor (of Space!). By the end of his day he may need a hip replacement with all the punting he'll be doing, but he will ensure the Penn State offense at least has a long field to work with. Unless of course Derrick Williams busts another return to the house.
