I see a lot of potential losses on Michigan's schedule. ND/OSU at home, MState/Northwestern on the road. I don't really know about Nebraska or Iowa but, historically, they aren't pushovers either.
Clemson's defense just isn't very good. They might lead the nation in scoring but they wear their suspect defense down by running so up tempo. Like FSU, they always lose to someone they should stomp. But, like you said, there's no one outstanding in the ACC. The winner of the Clemson/FSU game should go to the Orange.
I like Oregon/Alabama. Of course, Oregon has a few land mines along the way that could screw up their unbeaten season.
I think SC is much better than Florida and, if GA can replace all the players they lost on D, they're much better also. GA should score a ton of points.
