if floyd were around during the 80s...

Agreed but who were the Lightweight kings in the 80's?

Duran was finishing up at Lightweight. It's unlikely they would have crossed paths.
Chavez and Camacho would have been outclassed.

Sugar Shane Mosely came along in the early nineties....
had his first championship in 1994.

I would be rooting for JCC against Mayweather at Lightweight, and the greats above this weight Pryor, Hearns and Leonard would beat Mayweather if he decided to fight them. He probably would have settled for Comacho and Rosario, good but not great.
