ND and the ACC are bound together by various contracts through the 2036 season.

My guess is that they will stick together until/unless money disparity causes the ACC to break up, maybe around 2031 or so.

The GOR will not be much of an impediment by then and the Big Ten and SEC will be trying to raid the conference for its most valuable members to create two super conferences.

By that time, the Supreme Court will find that the players are direct employees of the universities.

ND will have to decide what it wants to do then.

Will it opt out of the pay for play, students as employees, big time super conference structure (with a probable breakaway from the NCAA) or will it join one of the two super conferences as a full member, including football?

I don't know the answer but suspect that ND will join one of the super conferences then, likely the Big Ten.

There will be a temptation for the Holy Cross priests who run ND to opt out, since they have always resented football overshadowing academics at ND, but that the alumni, boosters and fans (and the money and prestige involved) will win that battle in the end.

So, my prediction is that neither ND's football independence nor the ACC will survive the seismic changes that will take place in college football in the next decade or so.
