Calzaghe and Mayweather because they fought all conceivable challengers and took on the best of their era.
Rocky then Mayweather. Rocky changed ERAs when he beat Louis, if Mayweather can beat JMM,Pacquiao (which would decide this ERA) then the WW champ he will be #1, until then its Rocky.
Rocky and Ricardo, Calzaghe would go next, and... well Mayweather's record doesn't mean ****. Calzaghe fought both jones and hopkins, mayweather fought........
Jones was a beltholder in his dreams maybe. He was toast by the time he fought Calzaghe. Order: Marciano Mayweather Lopez Calzaghe I still rate Lopez higher than Floyd all-time due to a small push from H2H, and while Lopez faced a higher proportion of the top competition than Mayweather did, Mayweather's best competition was still better than Lopez's.
Man you're terrible. Jones wasn't a belt holder going in against Calzaghe. First Prescott is Khan's third fight and now Jones was a belt holder going in against Calzaghe. I suggest you improve your boxrec skills before typing, by the way, Calzaghe isn't Jones' second professional fight if you're confused with this one too.
Oh wow, just because I got confused by 1 thing. You're ****in stupid. All I hear from you is "boxrec" why don't you look something up yourself? You are truely a PBF, I can tell by your ignorance
