Has Floyd Mayweather ever had a signature win?

No it wasn't it was in shambles when he fought Pac with Diaz he was fine.

 

This is wishful thinking 101 if PBF was the betting favorite over the cash cow Oscar he sure as hell would be the favorite over a largely unknown to casuals in Williams or Margo.:deal You're also crazy saying that Cotto at any point of his career would be the favorite over PBF. Man stop reaching and give it up.

 

Floyd been the favorite in all his fights since Corrales. Its not a knock on his opponents That really speaks volumes on how good he really is.

 

You are right. He wouldn't be the favorite if he fought Kovalev either.

 

You just pointed out why people dont give credit to Floyd. Hes just too good to ever be the underdog even at 40. The last time he was the underdog was against corrales and he clearly won. ever since then there was no one he would be the underdog against. Even in 2009 he was the favorite against pac

 

Corrales obviously. Castillo rematch stands out to me because he answered all of the critics. His decisive wins of Corley and Mitchell his first fights at 140 and 147. Beating oscar delahoya, who although old was coming off of a master class against champion Ricardo mayorga, and weighed about 20 pounds more than mayweather in the ring. His destruction of young up and coming and eventual middleweight champion canelo. Beating the at-the-time 2nd ranked p4p fighter in the world pacquiao who would later go on to dismantle another top welterweight Timothy Bradley

 

it's been the same song and dance for the better part of a decade now.

Floyd is scared of this fighter, would never get in the ring with this fighter

FLoyd wins

Said fighter was shot, too green, shoulder injury, excuses ad nauseam

 

Only about 10 to 15 of them..
How dumb could some of you be, you have to try to be that level of stupid

"When he EASILY OUTPOINTED Manny Pacquiao in May in their long-awaited and record-shattering superfight, Mayweather not only cemented his position as the No. 1 fighter in the world but stamped himself as king of the era."

I don't know.. to be ranked the top guy in the sport as illustrious as boxing for a 25 year period. I'd say there are many wins to choose from. We'll just highlight the most recent.

 

The best win on his resume was chicanito

 

Genaro, Corrales, Castillo II, Gatti, Oscar, Hatton, Marquez, Mosley, Cotto, Canelo, Pacquiao

Take your pick.
