If a PFA gets formed, the leveraging power they will have over the UFC will be FAR GREATER than any other players association in any of the other major sports. When owners and players in NHL, NBA, NFL and MLB come to a head, the owners start implementing pressure tactics ie: Lockouts. And the players really don't have an equal or greater option to go to outside of those leagues. They can't just organize their own league so they end up either sitting at home or take far lesser pay to play in overseas leagues. If the UFC tries to lockout their fighters well, someone like Conor can just go do a PPV with Bellator and make equal or even more money with them. This can effectly destroy the UFC. The next couple of years are gonna be interesting. Can't wait to pay $100/ppv lol.
