1. Florida - They have the athletes to match up with USC on both sides of the ball. Urban Meyer is a big game coach.
2. Oklahoma - Ridiculous offense, but I'm not sure if their defense could stop USC. Also, they've been pretty lackluster in big games in recent years.
3. LSU - Like Florida, they have the talent to compete with anyone.
4. Missouri - If their offense has an off-game, is the defense good enough to keep them in the game? I don't think so.
5. Georgia - I'm just not that impressed with them and I think they're overrated. They needed a little luck to beat South Carolina last weekend. The real USC is a whole different animal.
That said, I'm not even convinced USC is the best team in the country. I think their win last weekend was as much Ohio State being bad as USC being great.
