The southern schools (Mia/FSU/CU) have woefully underperformed if you ask their fans how good they are. They'll talk like they have dominated the ACC for the past 10 years, won tons of BCS bowls, a couple MNCs, etc. In reality, FSU is about as dominant in ACC as BC has been (basically same # of wins/losses as per comment in link). Miami is going to be one of the 4 worst programs in ACC over the next 10 years (no MNCs/ACC titles leading into a *long* probation will kill that program imo).

Let those schools go to B12 and guess what... none of that will change. Stadiums will still be empty in Tally, Miami will still wonder why they were punished so badly, and CU will sell out every home game as they go about 8-4ish every season.
