If Floyd Mayweather Jr, Roy Jones Jr, Ray Leonard and Pernell Whitaker were the same size who wins

Sweet Pea is underrated IMO. RJJ had incredible athletic skills.

But Ray had the ring IQ advantage, just like Bud and Usyk have now.

 

Ray Leonard. Most complete fighter out of the four.

 

Roy.

 

All are the same size? the answer is clear ,,,Roberto Duran

 

If all were within the same size, proportion and weight class but with the same physical attributes, skills and ring IQ you have to favor Sugar Ray Leonard due to being the most well rounded and complete of them all.
