Is Mayweather a all time great?

[Julius Rain]

Theres no way you can say no. Even if he had lost to Castillo, Dela Hoya or Maidana. If he had lost those it wouldn't have mattered.

.....eh, maybe

If he lost all three then yes but 1 of those I don't think would of hurt as much as people put into his undefeated record.
