I do not think he is much better then the version that Jmm fought to be honest with you C lo and as for him slowing think the Mosely fight pretty clear. I am not sure how much better his prime was then Morles because most of his opponents were not in prime or coming off huge loses so i am not sure. As for resume its close but Mayweather not losing is kinda what edges it for me because he has not lost yet. If they do fight some time in 2012 or 2013 both been fighting for a while and i think there peak is over with really.
