I agree that under normal circumstances, each school has lost their respective vote. However, the reality is that though each is willing to pay the exit fee, if the conference is dissolving, they have a stake in the outcome. Upon disbanding, the conference loses the hoops credits and they revert back to the respective schools.
The issue then arises of what % of votes are necesary to break away. Assuming 2/3 (66.67%), though 75% is more likely, neither the C7 or football schools can force anything. The reality is that whether ND, Louisville and Rutgers have real votes, they have the power to mess up everything. They have already agreed to let the money go (exit fee and hoops credits) but if the conference does not stay toegther, they get the hoops credits and may not have to pay the exit fee. So, any agreement that does not satisfy all parties - C7, footballers, ND, Louisville and Rutgers will not work.
If the C7 demands the money, the football schools vote against it. If the football schools demand too much, the C7 voes against it. If ND, Louisville and Rutgers are forced into anything they do not like, they merely join the opposing side or file a lawsuit. As mentioned, the three leaving schools are willing to part with the money, but they will use this as leverage to get what they want, in this case, the date they leave. ND can be absorbed into the ACC this summer, no problems. Louisville could be absorbed if they slide into Maryland's slot, but that would require much more work. The B1G is not likely to take Maryland and Rutgers this fall. Thus, it seems that Louisville and Rutgers are not headed out this fall, but ND is not likely to be forced to stay with the football schools nore to play with the C7 when they can join the ACC.
Please do not misconstrue what I've sad to mean that ND, Louisville and Rutgers will be walking away with all the cash and leaving when they want. They are king makers and will get a nice benefit from making one or both sides kings (political sense, not football kings, we are talking about Georgetown and UConn for goodness' sake), but it will cost them.
