I think he just had an average night and Nate had a good night. Nate is bigger and stronger and more experienced. He really used his head alot, and not totally butting, but more pushing Juan's head where he could hit it. The cut was caused by a punch, but the punch landed because of the butt. Nate was using his head literally to set up punches.

I think his head caused alot of the eye problems, but the body work took Diaz's stamina. Overall the veteran tougher guy won, but it doesn't make Diaz a lesser fighter. He really fought the wrong strategy against Nate and he took a beating for it. He was right in is post fight interview to say that he didn't use his jab, he leaned too much on Nate and Nate was stronger and more crafty on the inside. Campbell fought very rough, used his head alot, but not enough to be penalized. Overall it was a very good fight and props to Campbell for the big win, and props to Diaz for finishing the fight strong cause he looked like he was gonna quit in the 11th.
