You are right. how the hell could one judge have Diaz win. I have seen a ton of Diaz fights and Ive enjoyed watching him, but he was torn up in this fight.
The ref tried to give it to Diaz too. He takes a point for a head-butt..that was a punch. Then he lets Diaz corner work on the cut during the round. Ridiculous. I think that Campbell knew he had to overwhelmingly win to get a decision. He may have thought he couldnt get one at all.
I am surprised with the chin of Diaz. Campbell is known to be a puncher and cracked him many times.
