Re: Better Wins: Pacquiao's Cotto-Magarito or Floyd's Cotto-Mosley
Good question. I would say Pac's over Cotto/Margarito.
Manny's win over Cotto was more dominant than Mayweather, and came earlier. There was no weight issue, despite what some have claimed in hindsight. Margarito was a middleweight on the night, probably more, and a decent one at that, so Manny's win is pretty extraordinary, from that respect.
Floyd's win over Cotto was less dominant. Mosley was overrated and a decade past his best at this stage and had been well beat on a number of occasions previously. He also hurt Floyd pretty badly early on.
I don't really, there's not much different. Four very good wins by any measurement.
