I predict Carwin winning by KnockOut Brock is a little (emphasize little) bit bigger and possibly a bit stronger but Carwin has clearly demonstrated he has more knockout power hell alot of his KO's he's barely clipped his opponent and kocked them out, Brock hasn't really knocked otu anyone cleanly the way Carwin has, except Couture but even then he stuggled in the first round quite a bit.
