Pac's career will ultimately be even more appreciated as time goes by. What he's done in the sport is astonishing and something that can't be repeated, at least not for a very long time. Legendary resume.
When did he refuse to test? Why do you repeat this lie over and over and over again? Are you dumb or a troll?
No doubt it is incredibly impressive but it should be noted that the Cotto and Margarito fights were set below the weight division limit. I always think that takes a bit of shine off the win tbh. Same as Floyd beating Alvarez Pacquiao fights Cotto below the full WW limit (where Cotto has to drop a bit more weight) and in his next fight is fighting at WW
