If what this article describes is true, then the ACC must feel like they are going to lose the lawsuits. Why else would you try to appease FSU with offers to pay out based on media value, and shorten the GOR term?
Also, has the ACC not learned from the appeasement they just implemented? FSU wanted unequal revenue sharing, they were given some, and their response was to slap the ACC with a lawsuit.
Edit to add: Shortening the term of the GOR makes no sense, as it was/is a requirement for the ESPN contract. Unless the ACC is hearing from ESPN that they won't extend, which is not what the word on the street is saying. Some of this stuff sounds like it's just rumor-mongering.
