Sorry, Diaz is a retard. Don't get me wrong, he's a great fighter and entertaining as hell, but the guy is a complete moron. Listening to him talk is one step above pulling all my fingernails out.
I would feel sorry for any fighter that he coaches, much like I do those fighters that Brock is coaching right now.
I'd watch it, don't get me wrong, but I think the fighters deserve better than that.
Plus, It'd be a ton of Diaz talking shit to GSP, only for GSP to crush Diaz like we all know he will.
