How many losses should Mayweather have on his record?

[Beanz]

Which other "greats" started their careers at a lower weight than Mayweather and had sucess at middleweight?

Duran, Armstrong. Other guys like Gavilan and Napoles started in lower weight divisions than Mayweather started and although they weren't successful against the middleweight champ at least they had the balls to challenge themselves.

What weight do you suppose Gavilan, Duran, Armstrong, and Napoles' respective opponents were the night of their middleweight title fights?

Does it matter? they were all great fighters, the likes of whom, Floyd, whatever one thinks of him, never had a chance to face.

Look it up yourself. It should all be there as fighters weighed in on the day of the fight back then. I'd say there was a 4-5 pound difference for Gavilan & Napoles from their opponents. I do know there was a 10 pound difference for Armstrong.

Duran started around 119.

I think the difference between present day weight cutting/day before weigh-ins, and the disparity between contract weight and fight night weight is extremely relevant if you're going to compare these fighters from eras gone by and contemporary fighters.

Would anyone agree?

I feel fighters from other eras often fought at weight disadvantages.
