Most underated:
Auburn, Va Tech, Wisconsin, Missouri, Alabama ( I know they are highly ranked, but I think they are the best team in the Nation)
Overrated
USC, Cal, Ole Miss, ND, Nebraska, Kansas (we will see this weekend but I don't think they are that good), Florida (Just because I think Alabama is better)
Underated:
Auburn, Wisconsin ( both of these have huge games this week) Stanford and Georgia Tech
Overated:
Ole Miss, Boise St.,Notre Dame and Kansas
I think Houston fell out of the rankings this last week.Houston, BYU, and Virginia Tech are 3 that come to mind for me.
