I agree 117-111 felt too wide.
That said, as I was watching the fight, I was saying to people on this forum that Pac was basically getting outworked and I pointed out that he's lost fights exactly like that before. Thats why he lost to Bradley. Thats part of why he lost to Floyd. He's turned into a guy just looking to land that big KO shot, yet he hasn't KO'd anyone in 8 years.
According to compubox, which I'm not a big fan of, Horn threw more punches in 9 out of the 12 rounds. Thats supports the idea that Horn won that fight based on effective aggression. All those times he was backing Pac to the ropes and throwing those uppercuts, all the times he was working in the clinch when Pac was not- thats why Horn won. Pac may have been more accurate but he's fought in spurts since the first Bradley fight. Whole chunks of rounds go by where he does nothing, he lands one punch and fans say he dominated. IMO, thats lazy judging and again IMO, I dont think most pro judges score fights like that. Thats why whenever a puncher loses, fans think he got robbed.
