I thought LSU should have been #2 also, but there's probably some new hidden rule about not having SEC teams 1 and 2. They probably figure keeping OSU #2 somehow validates the Big 11's existence.
As I stated before in a different post. It's not who you loose to but it's who you beat. Ohio State only lost 1 game and they beat No. 2 twice and a few other ranked teams. Still pretty impresive.
UGA is the highest ranked 9 win team in the AP as they should be. They should be ranked ahead of some of the 10 win teams as well. If you look at the final polls, this year has more 10+ win teams than any year that I can remember.
