I've been reading a bit on this today, slow day at the office. But as I've been able to gather, NOTHING is going to happen with ACC unless 8 teams have a guaranteed landing spot in the B10/SEC. And if they did, that would probably trigger some sort of legal action from the ACC. VT/UVA are locked in together. They're not going anywhere without the other. I've seen some say the NC schools are the same, and I've seen some that say that's not necessarily true. But I don't think it's far fetched to assume UNC/Duke have the same thought. Then you've got LOU, Pitt, GT, BC, Wake, Cuse, NCST that don't really add anything in terms of football. I can't imagine any would be B10/SEC targets.
I've scoured the interwebs, and I can't find anything that suggests some kind of strategy these teams could use to get out of this thing...other than "get 8 to leave", which seems like an impossible task.
So having said all that, I'm not sure what the B10 could do in the SE until 2036.
