As a professor once told me, if your strongest argument is public policy, you don't have an argument.
The other arguments, are obviously stronger. Penalty issues could make contracts voidable, but there is a lot more to it. The antitrust stuff scares college football people. We already know courts don't like college football model, and college football does not want the courts getting involved anymore than they already are.
I'm guessing, with the mention of Maryland's exit from the ACC, FSU is doing everything possible.to negotiate a much lower buyout here. It would not surprise me if they've been making phone calls to other schools to join and exert greater pressure on the ACC. I don't know what Miami's been working in or what their plan has been, but I would heavily consider making some noise moving forward if I were looking to leave...
