Could any of Mayweather`s opponents have beaten Bud as he is now at the age they were at when they fought Floyd?
Possibly Pacquiao. I would say Cotto, but that was 154. I would give Moseley a knockout chance as well.
Cotto was way past his prime when he fought Floyd. Crawford dominates even prime Cotto though at 140 or 147
And Maidana nearly beat Mayweather, what's your point? He also nearly KOed Khan, he'd be a live underdog against Crawford
The way he fought Floyd would have given Bud more problems than the way he fougt Khan, Bud is far harder to hit than Khan is.
It would be interesting to see Bud jump up to 154 and face a young Canelo, who was still a beast, knocking people out and ending their careers, and who hadn't yet become strung out on roids
