Unless we have multiple defections, I believe we stand pat at 14 teams. The football-first schools...FSU, Miami, Clemson, GT, and VPI...will vote against them everytime. I also believe that NCSU and Wake would, too. Thats seven 'no' votes right there. They'd need 11 of 14 'yes' votes, IIRC. They wouldn't get close to that number.
If ND ever joined full-time (a real stretch), and, they made adding UConn a condition of their joining (they won't), I doubt that they ever get an invite. I'd wager Cincinnati as No 16. Better football program, good basketball, and, Ohio is a hotbed for HSFB and hoops recruiting.
