Generally, a players’ association can respond to a perceived injustice or concerted restraint on player movement by decertifying the union, which exposes separate economic employers to antitrust liability. Prior to filing an antitrust suit (McNeil v. NFL), the NFL Players Association was required to do just that: it decertified, disclaimed all interest as the representative of the players in collective bargaining, and reformed as a professional organization in order to take up the antitrust case against the league.
As a result, the players were able to prove that the nonstatutory labor exemption no longer applied; because the NFLPA was no longer the bargaining representative of the players, the previously agreed upon restraints were removed, and the NFL teams were subject to section 1 scrutiny. The NFL responded that it was a single-entity, incapable of conspiring under the Sherman Act, based on then NFL Commissioner Paul Tagliabue’s testimony about his belief that the NFL’s business relationship is that of co-owners, and not of independent economic competitors. The district court rejected this argument outright based on precedent in other circuits when the NFL raised similar claims.
The NFL players did sue- the courts never found that the existing player contracts were null and void. The fact of guaranteed vs non-guaranteed doesn't matter- the only contracts in the NBA that must be guaranteed are that of rookie scale contracts for first round picks. Otherwise every other team DECIDED to give those players a guaranteed contract.
