No and it shouldn't. Hopefully he will be defined for being a supremely talented technical boxer, that was a master of boxing. The same way that Bhop will be regarded. If he was defined by his 0 then Joe Calz would be regarded on his level. I don't think many people would regard the two as being on the same level.
Floyd has a very solid record. However, he has not taken on the big challenges other great fighters have (e.g LW Duran who took on MW Barkley, Leonard who took on Hagler, WW Hearns who took on LH Hill). That will hurt Floyd in terms of legacy. :deal
