Here are some points King should clarify from his "sources":
1) How exactly would owners "lockout" a couple thousand independent contractors? Decertifying the union just signifies that the players aren't collectively bargaining the rules of their employment. At that point, the owners put whatever rules in place that they want...subject to US labor and antitrust laws. The players don't have to agree to the rules so there is no basis for a "lockout".
2) What specific conditions of their employment would serve as the basis for the players lawsuit? There are several possibilities (salary cap/floor, draft, trades, league contracts for TV/radio/marketing, etc) and the players would win the majority of these challenges in court.
3) How exactly would a victory in court compel the owners to play the players more money? Removal of the components in #2 above would certainly not result in owners opening up their checkbooks. The owners don't fear losing the salary cap/floor since they just lived through that in 2010. Losing the ability to collectively negotiate league-wide deals would destroy the NFL as we know it. How does that help the players exactly? In fact, the threat of a lawsuit is a much more effective weapon than the lawsuit itself.
4) So Doty could possibly rule for the players and declare the 2010 CBA rules (including the league/player revenue split) to still be in effect? I would love to see the legal precedent for that. "Um, your honor...I kinda liked my job situation last year and I don't like how my boss changed it this year. So even through those rules violate antitrust laws and form the basis for my lawsuit, I would like you to tell him to keep things the way they were and not make any changes. Thank you." Really? That is an option?
I have not seen a single talking head explain a scenario where a lawsuit (even a successful one where the players win every challenge) results in a positive outcome for the players. They could certainly use the courts to blow up the league, but I'm not sure that poisoning your boss and torching the only place of employment in your field is a good long-term career move.
