I voted Michigan for obvious reasons, but in all honesty I think Wisconsin has a good shot. They're just sitting around letting the East beat up on each other and then they can swoop in at the end and take it. All they really have to do is be better than two teams that finished sub 10 wins last year in Iowa and Nebraska.
I think it is either Penn State or Ohio State. Wisconsin will win the West.
Iowa is going to be that spoiler team IMO. They will be strong vs the run and passing teams with weak OL. If a passing team can give their QB enough time, Iowa is in trouble.
If Wisconsin is a ground-and-pound offense, Iowa State and Purdue might have a better chance at beating Iowa. Yeah, I know makes no sense.
