Floyd Mayweather GOAT?
I started this thread because I have this friend that says that Floyd Mayweather is pound for pound the best boxer of all time. In case you're wondering, he's never seen a Sugar Ray Robinson fight and has seen very little of Ali or Sugar Ray Leonard. He's pretty much mostly seen guys from when he was growing up from the '80s to today, guys like Tyson, Holyfield, De La Hoya, all the way up to the best of today. When I tried to disagree with him, he said I was just a hater. When I couldn't get him to listen to reason, I finally said that maybe I'd agree with him if Mayweather ever beats Pacquiao, Andre Ward, Sergio Martinez and maybe a guy like Carl Froch. I say Floyd is the best from his debut in 1996 until probably around the time he beat Ricky Hatton, so I say the best of his era, but not all time, maybe even the best from 1996 to today.
So anyway, do you agree with him that Floyd is the best of all time? Why or why not?
