The B12 commish says it might not be done expanding. That probably means at least Memphis is still in play. Not sure if they'd go for SMU; they already have four Texas teams, so another might be too much. If they were to take two more AAC teams I'd bet Memphis and either USF or Temple.
Tulsa and SMU seem ripe for the MWC. MWC had TCU at one point so getting teams from Texas and Oklahoma is logical. It already has 12 teams and found 16 to be too cumbersome a few years ago when it was the WAC, so it's doubtful it would add more than two.
Navy could easily go back to being an indy. They have a name, they have a history and they have a nationwide fan base, so finding quality teams to play should be no obstacle. They're a football-only member of AAC, so that's no big deal.
Tulane and Temple/USF could easily wind up with CUSA. They're all in or close to the CUSA footprint. Sun Belt, despite the presence of App State, Coastal and Louisiana, still has that 1AA/FCS feel to it.
I doubt that Temple (or UMass) would come back into the MAC as a football-only school. Neither ever really seemed to fit and for Temple (at least in its mind) it would be a step down. They thought going from the Big Least to the MAC was slumming it and merely used the MAC as a waystop until something they thought was better came along.
