They are contractually obligated to join the ACC according to John Swofford today at the ACC Football media day. That explains why Notre Dame signed the GOR, agreed to the $52 million exit fee, and has been genuinely positive about the ACC. I also imagine that there is language in their NBC contract as well as in the ACC's ESPN contract that plans for this possibility in the next decade. I thought this was an interesting statement by Swofford. He has not been that open about this before.
