I'm talking Sakuraba vs Belfort style, or like Wanderlei used to do a lot. Is there anything in the rules that prevent a fighter from doing this? It does seem that in America the refs don't really let the fighters just tee off on a guy's legs if he is on his back and his opponent is standing. They seem too eager to separate the fighters so that the guy on his back can improve his position. I don't think there is a rule saying that they have to do this so is it just that the refs are told to do this? I don't like it, IMO it makes the fight more artificial, if you can't get up your opponent should be able to beat up your legs. If anyone asks I don't like stand ups when both fighters are on the ground either but that seemed to always be the same in Pride and the UFC if your stalling on top you get stood up.
