Finito had a draw. Has any other fighter make it past 49-0, won universal recognition as a world champion and retired with a perfect record intact?
Problem is, a lot of people say Marciano fought in the weakest ever era of heavyweights and a lot of people also said his retirement was timed just as guys like Sonny Liston were on the scene. He doesn't get much credit for 49-0 due to these factors.
I don't think Floyd will get much credit if he ties or breaks the record by fighting Manny, the filipino jeff lacy. That was a one sided fight. He should give Thurman, Matthysse or a someone who desrves a shot.
50-0, in the mgm grand new arena inaugural fight, against his foremost nemesis - with a good injury storyline to play up. This is most likely in may 2016 (after he fights Khan in september) If no pac fight - a canelo rematch (after he defeats cotto for the lineal MW in sep/oct/nov) at 154.5 is also quite plausible as a big money ppv in mgm. I'd buy both these fights.
