Several former UFC fighters that switched over to Bellator spoke about their reasons for moving during free agency. Guys such as Ben Henderson, Phil Davis, and Josh Thomson cited a lack of actual negotiation, the Reebok deal limiting their income, and non-guaranteed backroom bonuses.

Among the many issues detailed, was a story about an argument Matt Mitrione had with UFC CEO Lorenzo Fertitta as his contract was ending. Here's how Bleacher Report had it:

The two sides had been engaged in a discussion regarding issues related to the Reebok sponsorship deal when the fighter tried to punctuate his point by reminding the executive that the 500-plus fighters on the roster are the UFC's product. As he recounts it, the executive looked at him quizzically before responding that, no, the production and show are what the company is selling.

The fighter could not believe what he was hearing.

"Without us, all you have is a cage, cameras and lights," he recalled saying, before the conversation continued in circles, ultimately ending in no resolution.

Mitrione ended up signing with Bellator shortly after losing his last bout with the UFC.
