Well, the smaller KBers has been taking knees, and kicks for a long time. I figure those are going to be harder than a bigger boxers punch as long as the boxer is not that much bigger. Unless Tenshin always had weak chin, and just never exposed. Now I did not expect Tenshin to win, but I did not expect him get knocked out like he did. I think now Tenshin KB opponents will head hunt with kicks more now.
