The nut shot completely stopped the momentum of the fight. Judah was getting beaten down with increasing intensity and there was a good chance that he was heading towards being stopped. The Vargas fans point to Trinidad fouling him to get a break in that fight. Last night was a much more obvious example of the same thing. They both had to start again cold and Floyds' intensity certainly dipped. He outboxed Zab in the 11th but wasn't going after him as much. Give Judah the 12th maybe for aggression (even if it was ineffective). He know he needed a KO and most of the time only hit fresh air while Mayweather celebrated.
