Seems like it would be fairly easy for the SEC, B1G, Big 12, and ACC to slide
into the PAC's place for most of these:
Alamo: Big 12 v. SEC(could include Texas/Oklahoma)
Las Vegas: B1G/SEC v. Big 12(preference for Mountain schools)
Holiday: ACC v. B1G(preference for Pacific schools)
Sun: ACC v. Big 12
Los Angeles: PAC v. MWC, with Big 12 and ACC as alternate if OSU or Wazzu doesn't qualify
Independence/ESPN: PAC v. Pool with Big 12 and ACC as backup if OSU or Wazzu doesn't qualify
