Socialism! Boo! Woke!
The individual ACC schools sold their media rights to the league until 2036. They do not own their own media rights. The ACC does. Lock, stock and barrel.
It is 100% legally the same as if I sold my house, was paid in full for it and came back 3 years later and said to the new owner that I wasn't complaining he defrauded me in any way or that he hasn't fulfilled everything he was required to do but I still demand my house back because it's worth more now. The ACC GOR is exactly the same scenario.
Now given the state of the legal system today, I'm not saying Half A$$ U and the taters can't find some friendly judge in SC or FL to side with them for no reason other than he likes how they vote or something. Clearly the law means nothing today to many jurists. But, unless the ACC's counsel is afraid of exactly that, they have no reason to give them an extra penny. And if the ACC thinks that giving into them now is likely to cause them to stick around in 2036 they are stupider than I think they are. And I think they are pretty stupid. See the Big XII and Texas
