If Silva were to fight Jones soon, I would expect the best of Silva to be brought out. He seems to bring out his crazy **** when he is legitimately threatened, at least on the feet. I would expect Jones would want to bang with him to prove a point, he's cocky that way, which is better for Silva, IMO. Silva is the type of guy to make a guy pay for mistakes -- I'm not sure some of the wacky Hollywood stuff Jones does on his feet would work on or phase Silva, imho.
This is the best fight to be made in the UFC. The two most talented, skilled dudes in the sport. I don't think either guy can beat the other easily. You'd have to favor Jones tho for his size and youth.
