I'm pretty sure you can't be in violation of a law you have an exemption from.
Opening the books to your adversary in a contentious negotiation would be idiotic.
Uh, you might want to check that. The NFL, was found to be in violation of antiitrust laws in the 90s. Remember plan B free agency? Anti-trust violation. The NFL, has a limited anti-trust exemption that allows it to negotiate TV contracts and black out rules as a league instead of 32 individual teams. It does NOT have a blanket anti-trust exemption. If the NFL tried to impose a salary cap it would be a clear anti-trust violation. The only reason it's not is because it collectively bargained with the NFLPA, a union. Collective bargaining can take precedence over anti-trust laws. In a sense that's an exemption, but if so it derives from the existence of the Union. Again, that's why the NFL wants a Union to negotiate with.
Only baseball had a broad based anti-trust exemption and even that's scaled back.
