From the article:
Over the past two years, a number of schools have sent teams of lawyers to examine the official grant of rights document, either looking for a potential pathway out or assurances that the biggest brands can't leave without a serious fight.
As one administrator told ESPN, those reviews have established several potentially compelling arguments for breaking the agreement but have uncovered no obvious loophole that would provide a pathway out without engaging in protracted litigation.
"Is it worth the paper it's written on?" one AD said. "If one school starts to leave, then another, how strong is it? It would involve a major legal battle."
And as one athletic director pointed out, it would also require another conference to extend an invitation to join before knowing whether it would have rights to broadcast that team's games. It's a legal Catch-22.
