They're at 17 now with the new additions. Let's say they lose 4, they're back down to 13. I think they add 3 to get to an even 16 (yes, B1G and SEC are up to 18+, but I can't see ACC adding 5 schools). My hope is the Pac-2 just absorbs the MW in some fashion and the ACC ends up adding us, Tulane (close enough to the current footprint, fits the academic prestige of the conference, strong football recently) and UConn (for the obvious basketball reasons), leaving the conference looking like this:
Louisville
NC State
Georgia Tech
Virginia Tech
Duke
Boston College
Miami
Syracuse
Pitt
Wake
Cal
Stanford
SMU
USF
Tulane
UConn
That's still a pretty strong basketball conference despite losing UNC and UVA. Football is still strong-ish with plenty of programs with potential with the P4 resources. Not sure what kind of TV deal that pulls, but certainly better than our current deal (obviously).
