In terms of rankings, college football's Week 4 headliner is Georgia-Notre Dame. That's fine. It should be a hell of a spectacle. But to me, Michigan-Wisconsin is the biggest game of the week.
We have so many questions regarding both teams. Can Michigan snap out of its early offensive funk? Was Wisconsin's early domination of lesser foes a sign of big things to come? Is Badgers QB Jack Coan really as good as he has looked so far? Is Michigan's O-line really as bad? Can Jim Harbaugh finally win again as an underdog (he's 0-6 at Michigan, and it has been a while since Stanford-USC in 2007)?
