I think Auburn's undoing is going to be the defense. Granted they haven't played a really strong offense yet, but the only thing stopping WVU was their own mistakes. WVU outgained Auburn 509-400. It took 6 turnovers for Auburn to win that game. Auburn will beat some teams, but I see them as a 4-4 type team this year.
It's definitely be interesting. I feel like the 4 teams behind Bama (LSU, Ole Miss, Auburn, and Arkansas) all have enough talent to play with Bama, but all have problems in at least one spot. All are dangerous and will be capable of beating some good teams, but I don't know that any of the 4 will do it enough to challenge Bama.
