Hard to say. I’ll break it down like this:
Definitely leaving: Florida State, Clemson, North Carolina, Miami, Virginia
Could leave based on political maneuvering/state involvement: North Carolina State and Virginia Tech
If that is enough to collapse the value of the ACC below the value of the Big 12 (and I think it will), schools like Georgia Tech, Duke, Pittsburgh and Louisville may move over to the Big 12.
I see Florida State and Miami in the B1G.
I see North Carolina, Virginia, Clemson (and maybe one or both of Virginia Tech and North Carolina State for reasons I just mentioned) in the SEC.
If the SEC snubs Virginia Tech and/or North Carolina State, I think the Big 12 will desire them.
The ACC then backfills with UConn, Washington State, Oregon State, and the best brands left in the American, such as USF, Memphis, Tulane, etc.
