Oklahoma

USC
103-24 81%, 7 Conference Championships, 7 Divisional Champs, 7 BCS Appearances (6 of them won), 2 MNCs, 3 Heisman winners.
Pretty comparable for these two programs if you ask me. The only part that puts my favor in Oklahoma's court, is the fact we can say they did it without paying players or their families. Clean program over a dirty one any day.
Oh and to the OP, there is no way I would even consider NU being top 10. Callahan alone ruins this, then to add the debacle we had against Colorado and Miami in back to back games.
