you are partially correct... http://www.tellshowbcs.com/SOSP.html
texas had the strongest schedule in the nation and they beat oklahoma on a neutral field by 10...
what you are wrong about is usc... if they were as good as you say they are they win two days ago 65-10 but they have inept play calling and unfocused and undisciplined players to say the least.
alabama is not a bad team, utah is an awesome team who could beat anyone if the circumstances were right...
I don't know about all that...Oklahoma easily played a better schedule than Texas. OU played TCU and Cinci before Big 12 play even started. You could easily argue USC played a tougher schedule the way the PAC 10 finished the season.
In regards to USC, I'm convinced they are the best BIG game team in the nation. When they get ready for a big game no team in the country is better.
