I think UConn and Rutgers would have no trouble stabbing the BE in the back, and I think TCU gets invited to the Big 12 if Missouri leaves.
If Louisville, Cincy, West Virginia, and South Florida commit to staying, Temple and Memphis should be brought in for all sports, and Army and Navy for football only. Eight football teams, and the basketball isn't unnecessarily diluted by East Carolina or Marshall. 14-team basketball league, and make the penalty for leaving 5 years and 25 million.
