Most people will agree in corrales' one being the most impressive performance of floyd. Genaro's one was very impressive too tbh, taking into account how young he was and how good genaro was. He has a lot of impressive fights tbh, there are plenty of them.
The Gatti beatdown was brutal The Hatton KO was picture perfect The JMM comeback he looked sensational
I forgot about the Genaro fight because it was so long ago. That's right, Genaro was undefeated and expected to give Floyd all he could handle.
Best performance = the performance that Mayweather looked best in. That'll be Corales, Gatti and Canelo. As There Will Be Blood stated, the JMM fight has far too many asterisks.
It's a toss up between Corrales, Gatti, and Canelo. I think Canelo because he showed so many tricks, won almost every round, moved out of his natural weight class to fight a bigger man, and Canelo was at the top in the division.
Came here to say the obvious Corrales & Gatti were both masterful beatdowns I was huge a huge fan of both guys and Floyd beat their asses. Gatti legit barely landed a punch.
I agree with the above posters choices Mayweather best wins were against Alvarez,Hernandez and Hatton who were all top fighters when he beat them with ease.
