Personally, I think you guys are just throwing Nick excuses. I think it's more like Dana said. Diaz is a fighter, nothing more. He's not interesting in the behind the scenes and the pre-fight, he just wants to get in there and have a fight. He's the kind of guy to say "Fuk Dana, I couldnt give a shit if he's moaning about me. He's the one making money off me so he'll do whatever the hell I say" before passing the bong.
Thanks to Ape for the sig.
