jet li... anyone ever seen unleashed? Some guy about the size as the only dude that beat kimbo took a punch to the throat from Li and died. I know it's a movie but jet Li could make that kind of a punch possible. Also, brute force(Kimbo) almost never beats technique(Jet Li).
edit: and for those saying jet li only does stunts in movies... you say that because you don't see the fight videos recorded in china
