"The guy says the dumbest s--t I've ever heard in my life, and he's very delusional," White said. "That being said, I think he's an incredibly tough guy. With his physique an everything, I'm blown away how he can compete at this level and how talented he is and what a great chin he has. But very time he gets above No. 5, he looks like he doesn't belong in the top-10, you know what I mean?
"You get him above No. 5, and he doesn't look like he belongs in the top-10. You get him in there with some guys that aren't, and he looks like a world-beater, and everybody starts yelling, 'He should get a title shot.' And then you see him fight guys who are athletic and talented, and he looks like he doesn't belong in the top-10."
"He said Cormier wasn't engaging enough," White said following UFC 166. "He outwrestled him, and he punched the living s--t out of him. How much more does he want to be engaged? He says some dumb s--t, and he's very delusional.
"He says we've never given him a title shot when we should have given him a title shot. Every time you get that close to a title shot, you get beat by the best in the world. That's why you've never had a title shot."
White says he is trying hard to get along with Nelson, but that the relationship has always been a strange one.
"Contrary to popular belief, I try so hard to like Roy Nelson," White said to a small group of reporters following Saturday night's UFC 166 press conference. "It's like I saw him backstage before I came out to talk to you guys. I was like, 'What's up Roy? You looked good. You lost weight,' and this and that. Then I come out and hear the stupid s--t he said to you guys right before I walk out there."
