http://www.boxingnews24.com/2015/03/roach-cotto-says-pacquiao-is-going-to-kill-mayweather/ he's seeing Pac training and is worried about Mayweather.
The problem here is that Cotto believes he beat Mayweather. Ask Cotto who would win between him and Pacquiao, and he'd say Miguel Cotto is a better fighter today. In other words, Cotto is not the one to ask for an honest opinion.
Cotto dislikes Mayweather just like everybody else, these people have some personal against Mayweather more then boxing.
Well since Cotto had a lot more success with Floyd and actually hurt Mayweather a few times. And the one little thing about how when he and Manny fought he was nearly beaten to death. Cotto may have a point.
