I agree with this. Minnesota is free to schedule anybody, outside of conference or other contractual obligation.
I'm not so sure about this. Minnesota alums have a tremendous deal of clout, and money. They're going to need to pay for that new TCF stadium somehow, as well as figure out how to get people back into Williams. I recall UND has about 7000(?) alums in/around MSP, as well it's a short hop for others in the upper midwest. My guess, since academia is generally one big whorehouse, is that any new policy will allow some 'case-by-case" exceptions, perhaps based on existing rivalries in other sports.
I think a pivotal issue is any settlement with the NC$$. If the parties figure out a way to "make nice" before trial, it may open a few doors, or at least get "The Scarlet A" off UND's chest in some quarters. I don't see a jury verdict for UND having the same effect.
