I'd say Spinks, who did clean up a great 175 division (beating 2 or 3 ATG's in that divison) and going up to heavyweight to beat a 48-0 world champ who is IMO a top 5 heavyweight of all time. He may have been on the slide, but he still went on to achieve quite a bit. If Cotto destroys Manny that will look good, but I think he also has to beat PBF to be on Spink's level (although its close).
Who is Fraud? :rofl You must be talking about the man who claimed to be your father all this time while pimping your mother:rofl I've been watching boxing for a long time, before what you call BLING was invented. :rofl
Yeh it is close, but when it is all said and done Mayweather has more names on that resume currently.
