I wonder if Rafa has considered MMA. Im sure right now he is happy to be building his BJJ legacy, but later on ... he could be a force.
I know he is a guard player, but the way he flows so easily, I don't see that GnP would last very long before he had you all tied up. I mean, if he can gramby halfway to turtle, hit an omaplata on the roll back, and then quickly go from on his back to attacking a belly-down armbar to the back, then even peppering shots from on top would be a dangerous proposition. Plus, that was Justin Rader. Imagine most MMA lightweights or welterweights trying to defend that.
