Mayweather has some decent names on his resume,,,, but regardless of that,,, it is the manner in which he has beat his opponents that backs up his talk against Pac....


He couldn't smack talk guys at say, 154, because we've seen that he's not willing to step to far out of his comfort zone... And if he did start talking smack about guys at 154, the immediate thought that comes to mind is "Well, put your money where your mouth is"...


But as far as Pac goes, Mayweather's career has everything required to back up his mouth....
