Wild Turkey, added some minor comments above.
Here is the thing with ND:
1. They aren't actually going to join the ACC unless they have to because they are eating their cake and keeping it too.
2. They don't have to do anything because anyone will take them at any point so from their perspective the move would be 100% financial. The only thing that would change that is if they are left out of a playoff system which isn't likely anytime soon.
3. The odds of the SEC being in contention for ND is extremely low as they aren't going to give up the USC, Navy and Stanford games if they don't have to and the B1G gives them access to Michigan and Michigan State which have been rivals in the past.
The only interesting thing I've seen lately that has changed my thinking is that UNC might prefer the B1G over the SEC if the ACC folds. I think the fanbase would overwhelmingly want the SEC but the administration seems to lean heavily to the B1G for academic reasons. One thing is for sure the ACC is UNC's league so they aren't going to do anything unless there is no other choice.
When this thing is over (which could be in 2036) I think we see the SEC pick up:
FSU
Miami
VT
Clemson
I had it at UNC, Duke, VT and either Clemson/FSU/Miami but if the SEC can't get UNC they won't take Duke but we might see NC State as the 4th choice to get in the state of NC but the truth is the SEC will have to go with bigger names to counterr the B1G move.
- ND is the biggest get on the board
- UNC is the second but the margin is between them and ND is wide
I still think the B1G would rather go after the ACC schools but you could see a situation where they go after some more of the PAC but I'm not convinced that makes a lot of sense for them. What does make sense is ND, UNC, Duke, GT and Virginia but someone on that list will get left out. ND might also push to get Stanford (the SEC is not going to add a PAC team) so that would leave one or two of the ACC schools out.
I would be shocked beyond belief if ND joined the SEC as I don't think that is even a remote possibility because they will have more attractive options open to them.
As it stands right now to kill the ACC GOR it will take 8 votes and ND doesn't count so that is 9 schools moving and the numbers at that point get complex. Add in that UNC is going to fight it to the bitter end and odds point to the ACC surviving for now.
