Plus I can't blame Diaz for not wanting to eat their shit. One could say he's an idiot for it, personally I admire the guy for not playing the game the way everyone wants him to play it. The comissions are full of shit, everybody knows is, nobody is doing anything. Everyone is just eating the next bowl of shit and saying "Oh, man, this tastes good!". I completely understand how the dealings of the athletic comissions can turn somebody against them.
And it would be terribly boring if he crawled back to them and nicely asked for a license.
