UFC is treating their fighters like shit, they don't allow them to have their own sponsors, or to fight with boxers if they want, and more fighters are now having courage to say that in public, like Tony Ferguson did few days ago, or Francis Ngannou before him.
It is true that the UFC fighters are not allowed to wear their own sponsors during the fight night but apart from that they can promote them at will, Not heard what Tony Ferguson said about the payment but Francis Ngannou knows very well that if UFC let him go that he wont be getting the same payment anywhere else. He is dreaming about a boxing event against one of the greatest boxers in Tyson Fury and for that Dana White is not letting him do that because that will harm the UFC brand if he looks foolish boxing against Tyson Fury.
Why do you think some of the best fighters like Cris Cyborg left UFC and signed for Bellator, than you have Patricio Pitbull and arguably one of the best fighter and legend Fedor Emelianenko is in Bealltor and he never signed for UFC.
Overall UFC probably have more quality fighters, but many champions in other organizations can fight equally with champions from UFC.
Cris Cyborg left because she felt she is disrespected in the UFC. There is a reason Fedor Emelianenko did not sign with the UFC, his demands of co promotion with the UFC was not accepted by Dana White. I do accept that Bellator has some talented fighters and i would like to see a cross promotion mega event once a year which would be awesome
But you know Bellator 280 had surprisingly more balanced match ups.. I wish they did more of that.
