We have the last two offers from the ACC and Big 12:
ACC: Nothing. They didn't even bother to offer us the SMU deal.
Big 12: Basketball only, matching the Big East's payout, and we would have to commit tens of millions to football on the off chance that they accept us as a full member in 2031 or thereabouts. The Big 12 never formerly offered us this though, and discontinued discussions.
There is no negotiation or doing a little better if neither league wants us at any price. I don't see anything changing. What new information will the ACC or Big 12 get about UConn? Our basketball program is pretty good, football is what it is, we are in a wealthy market near New York that no school currently has. Everyone knows these facts, no one wants us.
Something has to change with our offer or these two leagues for the deck to get shuffled. We can wait for them to lose members, which feels likely to me (I think some schools are simply going to stop trying) but it could take a while, or we offer them something they haven't seen before. I think the Big East starts a discussion with both leagues about merging the Big East with them. It doesn't cost the ACC or Big 12 much, upgrades the ACC basketball, gets both leagues a whole bunch of cities, and gets UConn football a home.
Or we can continue asking nice as we have every year since 2002 and see where that gets us.
