I gotta pull for Renzo mostly cuz I'm a bit of a Gracie nuthugger. I also respect him the most over his brothers and cousins because he actually trains outside the family. Now, he's still not a great striker, but at least he tries. I realize, however, that Pat has argueably the best fight team in MMA and was quite a force in his prime, so he must be doing something right.
I will definitely be pulling for Gracie, but I think the smart money is on Pat.
P.S. I FUCKING HATE TIM SYLVIA!!!!!
