"You're just mentioning names. And they're only important names why? Because they fight for the UFC. Or else they'd be nobodies. The UFC does a great job of pushing them, and they're popular. It doesn't mean they're talented. It just means they're known... I guarantee that if you put them in a tournament structure like Bellator, they're not going to win it every time. Gray Maynard? Kenny Florian? All these guys, they're UFC fighters, that's all. They're pushed by the UFC, but when they leave the UFC, they're forgotten. When's the last time you heard Josh Neer's name? You haven't. When's the last time you heard about Roger Huerta? You haven't. They're no ones anymore. What were they two years ago? They were superstars."
