It would be nice if they finalized the playoff system before some of those teams started play in their new conferences. Everyone just goes back where they came from, no harm, no foul.
If there's no AQ, it would be nice if the conferences with the most chaos right now (WAC, MWC, C-USA, Sunbelt, Big East) all sat down and tried to figure out logical homes for all their schools, including the FCS/new FB schools who have already committed millions of dollars to start or upgrade their programs.
If ACC would just hurry up and rescue UConn/Rutgers already it could really pan out to everybody having a logical home.
BSU/SDSU/BYU - back to MWC to make that a good conference
SMU/Houston/Memphis/UCF/USF/Cinci -all back to CUSA to make that a good conference...it's where they started more or less
Louisville - B12 or ACC somehow, maybe back to CUSA where they were
Old Dominion, Georgia State, UNC Charlotte - could still be promoted but do it in Sun Belt where it makes more sense
Texas State, UT San Antonio - could still be promoted but do it in WAC or Sun Belt where it makes more sense, WAC stays alive this way without the Utah State, San Jose state movement.
If you dissolve the Big East football portion and slow down on the FCS promotions everybody has a home that equates to where they were 5-10 years ago or a promotion.
