"These guys go out and sign with these rinky-dink little promotion companies and sign these bad contracts, and let's just say Roy Nelson is involved in a bad contract right now that he had before," White said back in November. "There's a couple of different organizations out there that do it."
I'm surprised nobody else has mentioned this part of the article. As if the UFC doesn't control the fighter's lives while they're under contract. I guess you could argue that the UFC is "the big show" but they still have VERY restrictive contracts with their fighters.
