Let's get wild with speculation ...
Scenario 1:
Texas A&M and Baylor go to the SEC.
Texa$, OU, OSU, and TTU go to the Pac-10 with Colorado. That only makes 15, so ...
Utah to Pac-10.
Boise to MWC to replace Utah.
Scenario 2:
Kansas, KSU, ISU, Missouri, Baylor scoop up the FB playing part of the Big East.
That leaves nothing for MWC to pick up.
