I don't know why the SEC would take those 4 schools. But if they somehow got out of the GOR, it would be wild. I don't think the B1G wants anybody in the ACC except Virginia and UNC (ND of course). So they'd be out. My guess is they'd backfill, and I do think WVU and Cinci would make the list, and possibly UConn. That would help the Big 12, which needs to expand westward. Not sure where UCF lands, but the ACC would probably want them if they lost FSU.
So UCF, Cinci, WVU, UConn to ACC. Big 12 then expands with most of the PAC and keeps Houston.
