There isn't any proof that Pacman cheated at all, I think they just didn't want to fight Mayweather at that time, and he was pissed off by what Mayweather's camp was saying.

I think Cotto looked pretty poor against Foreman, a guy he would have absolutely crippled on his own a few years back. He didn't sink shots to the body like he used to, he didn't show the same ability to counter speed with his timing, he looked far more timid than in his prime, and just as easy to hit.
