Diaz is an idiot. Seeing as he can't hurt GSP he goes all out to hurt his feelings by calling him names
I wonder how long it's going to be until Dana White says something about 'unprofessional conduct' Diaz is working and he's in the main event. Promotion is good before the fight but he is making the company look bad.
GSP is doing great here but Hendricks or even Ellenberger would have a great chance of knocking him out. He seems to react very adversely to getting punched.
