Question will be how does this affect the bowls. If the bowls can survive this, and still have their conference tie-ins with a big payout, it may not cause the conference to shrink in size.
IF you are Miami or FSU, and still have the Orange Bowl option with a huge payout option, why leave when your chanes of making that game are greater in the ACC?
Until we see what impact his has on the bowls themselves, unsure what will happen.
