The UFC would never sign a 2 fight deal, especially for him. He would also be subject to tolling (which he explained how they routinely abused with him, including sending him a bout agreement with a date they knew his visa would not be renewed by) and a 5 year contract.
Aside from paying out a absolutely atrocious 18% of revenue to fighters (which includes every single penny of bonuses, PPV share, purses, insurance, travel, even the performance institute) the UFC has predatory contracts where they have ALL the power.
Francis fought out his contract and the "hE sIgNeD tHe CoNtRaCt" crowd are still complaining. Get a grip.
I'll watch Franics fight in any org because he's one of a handful heavyweight fighters on planet earth that is of interest to me. I could care less what the logo on the cage floor says and an announcer telling me to eat corn nuts. I watch and pay for the fighters, not the promotion.
