I believe brock will beat carwin as easy as he beat mirburger. He has way more speed than carwin, way better wrestling & punching power. Just compare mirburgers face from each of his fights with the two guys plus he hit herring so hard he flipped backwards. Dont forget the hieght advantage. oh & carwin was getting manhandled by gonzaga in that fight in the wrestling department. gonzaga just got caught. brock has a tougher chin i suspect
