not sure who wins but ill bet this ends up being fought almost exclusively standing up against the fence
It's an interesting match-up given that neither one of them can wrestle their way out of a wet paper sack but I'm favoring Werdum. He's actually the better technical striker so barring a monster punch on the feet he probably pitter-pats his way to points there and if it ever does hit the mat then Werdum holds a colossal advantage. Werdum UD.
