In the opening week of NCAA football the Big 12 went undefeated. The Big Ten did not. The PAC-12 did not. The almighty SEC also did not. The Big East went undefeated, though it would not have if TCU would be in their line up as the Horned Frogs were defeated by unranked Baylor from the Big 12.
If the Big 12 collapses it will not be for a lack of athletic competitiveness. Sure Colorado will probably be a ringer in the PAC-12 this year boosting the relative rankings of established teams in the conference, but it could be interesting seeing what happens when Nebraska hits perennial Big Ten favorites Michigan State, Ohio State, and Wisconsin. Nebraska also lost its membership in the AAU which probably hits on the scholarly image of the Big Ten.
