I'd add, that the ACC has been in the quandary for a decade now. They expanded into New England with Boston College and to the edge of Florida with Miami while bringing in Virginia Tech - the second best Big East football power - in the process. What did it do for them in football? Nothing much really.
Miami is only a factor when they are a contender. The whole City of Miami is a ring chasing bunch. They were a Dolphins town under Shula, a Canes town from the late-80s through the early-2000s, and now they're a Heat town under the Wade/Shaq and Wade/Lebron runs. Miami hasn't been a contender and therefore they've been a market non-factor to the ACC. Boston College is in the heart of pro sports country. Virginia Tech has been their biggest win and they don't even compete well against the elite of the sport.
They over-expanded their sphere of influence and bought into two brands that really add very little when they aren't a contender. VT was basically just the tagalong to get them a ACCCG and they've been the best inclusion of the bunch. I'd be wary of expanded into markets where college football isn't king. Texas A&M and Mizzou were good fits in that regard. I'm concerned about going into North Carolina expecting SEC football to become a big deal there.
