SEC- North Carolina and Virginia (state flagship schools, contiguous geography)
Big 10- Miami and Georgia Tech (AAU and markets 1/2 shares at first)
Big 12- Clemson, Florida St, Louisville and 1 of the following NC State, Va Tech, people will say Pitt, can't see it- does W.V really want them? what do they add really? I would personally take NC State, and can you imagine if Yormark could convince Notre Dame to switch their 5 game scheduling agreement to the Big 12!!!!!! They dont want to go to the Big 10 (anti-catholic history, and yes I know $ talks) and the SEC won't take them (not a southeast school- unless you count Kentucky...hmmm)

the rest are all left out as the league implodes, west coast schools go back into the reconstructed PAC 12, SMU back to the AAC and the rest go into a reformed ACC which is now G5 school

this would give the Big 12 (Allstate 20 conf) schools in most of the large growing US markets with some decent flagship schools of their own, Good in football, murderers row in basketball... add ND and its even better.
