Duran (version of Leonard I) vs Mayweather at welterweight. In my view, Duran takes this via UD. Duran would keep up the pressure during the whole 12 rounds and rib shots to the body and head. He would be much busier and agressive than Maywaether, landing and throwing many more combinations. Mayweather would be kept mostly on the defensive. Mayweather, the technchialy more sound fighter, would land effectively in spots. But not enough for Duran who is a suppreme defensive fighter and has a granite chin.
Duran by ko. He was mean, nasty and better than all of Floyd's opponents to date. Of course, Floyd would have never agreed to fight him in this fantasy match.
In what universe would Floyd get in the same ring as Duran? Even as a fantasy match-up this is stupid..
Duran also quit in a WW fight because he was so frustrated by foot movement, tight defense, potshots, and getting clowned. Mayweather is capable of those things. Just saying.
Duran, who kept the pressure on Leonard for 15 rounds, would do the same to Floyd, who doesn't hit as hard as Leonard. Also, Floyd doesn't have Leonard's footspeed, which was crucial in avoiding getting knocked down by Duran. The style match-up is all wrong for Floyd. I would take Duran either by UD or by late KO.
They guys that beat Duran had a bit more pop than Floyd. Duran on 24 7 would be something. Duran via wide UD. Floyd is one of the only fighters I would say is close to unstoppable.
At WW Floyd all day every day. At LW Duran all day every day!! Nobody beats Duran at lightweight, not even Floyd.
