If Diaz is smart he would hang in Pride until he gets a title shot (which should be soon). If he wins the title, or he can win the lightweight Grand Prix Torunament, then he should go back to Dana and he could come into the UFC lightweight division as a Grand Prix Champ like CroCop, or as Pride Champ.
I love both organizations, and anything that pits top fighters from one organization against another will mean top dollar for the fighters and huge buy rates for the MMA promotion!
Zuffa and Dreamscape Entertainment, need to see that, accept it, and go for it. Trying to be like Vince McMahon and take over everything is a mistake and will get the sport nowhere!
In fact I think they should cooperate as much as possibel!
