Exactly, the SEC and Big 12 have a competitive level that can’t be touched by the Big-10 or the Pac-10. The ACC is on its way up. But for now, the SEC owns college football.
Do not forget the Big East, is also moving on up, having gotten the respect it so richly deserves this year. But yes, the SEC is in charge of college football.
The Pac 10 had good teams this year. USC and Oregon were top ranked until QB injuries knocked them down.
