Man, just what the hell is going on in College Football?

Florida State in a dogfight today, Michigan getting blasted at home again, Wisconsin in a dogfight, Auburn getting upset, Tennessee losing last week, Texas in a tough one, Hawaii barely winning, Boise State getting upset. Whatever happened to the "powers" of college football? The only ones winning that are supposed to are USC, LSU, Florida, Oklahoma. And that's just week 2!
