I think Mayweather is outstanding and could have beaten any of the guys he beat in their respective primes. But, he didn't fight any of them either in their primes or before they were shopworn. He's the best matchmaker of all time, not the best fighter. Had he fought Margarito when Margarito was peaking, I predict he'd have been run out of the ring. Instead he retires for 2 years and comes back and fights a fat Juan Manuel Marquez where Mayweather deliberately missed weight and made no attempt to lose it rather paid a few bucks to Marquez. Not even bringing up his domestic abuse history, he is a total piece of ****.Its hard to say, I remember people thinking Mosley for going to destroy Mayweather and that didnt really end too well after the first couple rounds.
Can we really say Canelo is too big? Well, he was too big and Mayweather fought him and thats that lol
Mayweather is just a great defensive boxer. Dunno if GOAT but he is pretty good.
Who else did he beat? DeLeyoha (past his prime of course,) Cotto, Juan Manual Marquez, Judah, Gatti, a few other solid fighters.
I wish he had more under his belt and in different time periods thats for sure.
I like Manny P. more than Mayweather though. 1 of the few matches of what if it took place when it was supposed to take place.
