Mayweather:

Corrales- weight drained when he lost to Floyd, and had to cheat to beat Castillo. Never elite.

Castillo-LOL, he lost twice to Javier Jauregui, who? He got lucky decisions versus Casamayor and Stevie Johnston and had to cheat to beat Corrales. Never elite.

Arturo Gatti-glorified club fighter with no defense who was past his prime.

Carlos Baldomir-LOL, one of the worst champions ever. Look at what a past his prime Vernon Forrest did to him. Only contribution to boxing is new scale on which to gauge other gigantic headed fighters.

Zab Judah-lost to one of the worst champions ever. Was always overrated.

Hatton-original poster already covered this.

Oscar-maybe a great fighter once but he almost always found a way to lose or get controversial decisions in the big ones. Plus he was past his prime.

Meh, I don't even believe this about Floyd but that's besides the point. Somebody probably agrees with it though
