Who comes close to being a "perfect fighter?"

[JazMerkin]

Ricardo Lopez
Salvador Sanchez
Floyd Mayweather Jr
Roy Jones Jr
James Toney
Larry Holmes
Alexis Arguello

Are some that come to mind.

I agree on the first 3.

However, Jones lacked the urge to finish fights when he could have at times, & I think that means he can't be.

Toney has all the natural physical abilities to be a perfect fighter but his lack of interest in conditioning & so on means he loses out for me.

Holmes is close, although I'm sceptical whether his handspeed was good enough to make him 'perfect'.

Arguello I agree on.
