I'm an attorney and FSU's lawsuit is really a single issue case. All of the antitrust stuff isn't going anywhere. I doubt all the arguments about the ACC's ineptitude will either (even though it's extremely true that the ACC is corrupt and incompetent and was largely a vehicle to enrich the swofford crime family).
The entire issue boils down to that extension that phillips unilaterally gave for ESPN to renew the deal. If the court rules that he wasn't allowed to that, FSU is going to immediately break the contract and sign up with the B1G and tell the ACC to go **** themselves and sue for damages. When the ACC does, FSU will argue that their future media rights were 0 because the ACC has no contract in place. The ACC will try to negotiate a new deal but nobody is going to make an offer anywhere close to the current ESPN deal knowing full well that FSU/Clemson and *hopefully* us are about to bolt.
if the court rules that phillips is allowed to just unliterally extend the deadline, i suspect ESPN will renew the contract and then the price to leave jumps up into the hundreds of millions and everyone stuck in the ACC slowly gets bled to death by the wake and BC parasites until 2030 at the earliest.
