Odd that the UM source says neither of the big 2 has extended an offer. I wonder if that is being carefully stated, as it doesn't necessarily mean that neither conference has reached out to UM to discuss the matter. Maybe they don't want to say there has been a formal offer because it could lead to lawsuits against the school and the poaching conference (and also possibly a lawsuit by Disney).
Also want to add that the performance based payouts is inherently stupid and destroys any semblance of parity. For some reason no sportswriter has picked up on this. It means the good programs will get considerably more money, which then puts them even further ahead of the bad programs. The bad programs need the money to get better facilties, recruiting budgets, etc to compete with the better programs. It's a pathetic capitulation by the really bad schools because they know they aren't likely getting an invite from the SEC or B1G, so they would rather bend over and take it from Clemsons and FSUs, (and hopefully soon, UM) so they can at least get their 40 million guaranteed. The good football schools should say no way- if they walk they can get 100 million per year, no matter what their record is. If they have a couple down seasons, they will still be financially on par with the other programs, whereas in the acc they will end up taking a massive pay cut.
