My unbias opinion is Duran by TKO 11. Floyd will outbox Duran early because roberto was partying all night and just woke up two hours before the fight. Manos will hurt the body when Floyds doing the shoulder roll against the ropes. Floyd will potshot but Duran walks thru them like he walks thru rain. Floyd starts slowing down in the 7 round and starts eating right hands of stone to the face. By the eleventh his face is a bloody mess and can't see Durans right hand coming and the ref steps in and stops the fight. Floyd shows mad heart and never goes down .
Not only would Mayweather lose, he would get utterly dominated. Duran would be stylistic poison for the 147 version of Floyd who likes to fight at a slow controlled pace and doesn't have anywhere near the power to get Duran's respect. Mayweather would be in a defensive shell every second he was on his feet, he would try to move but after a few rounds his legs would be gone due to Duran's body attack. As the fight went on he would get hit more and more and punch less and less. He gets stopped in the 10th, utterly shell-shocked in the face of the educated savagery of Duran. It would be a one sided ass-kicking from the opening bell. Floyd would need to go to a **** crisis center after the fight.
Can I also say that Floyd would look like a man with no clue of defence in this fight. Duran could hit him with any punch from any range, and let's not forget that Floyd just wouldn't fight anyone near Durans class.
Duran UD over a battered Floyd Mayweather, who finally captures the heart of the boxing fans by participating in a moving losing effort.
Castillo beat a peak Floyd at 135 IMO, but Duran is a poor man's Castillo. I think the fight would resemble Floyd-Castillo II, with Floyd 'dancing with the stars' throughout and making Duran look like 'Feet of Stone', keeping the uncultured Panamian at bay with a single stiff bodyjab deterrent, and using his silky sexy footwork to prevent Duran from cutting off the ring. Duran was just a savage anyway, Floyd could let him inside then outfight him there like he did with Ricky Hatton, who was a better bodypuncher than Duran and PBF still schooled Ricky. Floyd v Duran on the ropes would be similar to Floyd vs Philip N'Dou, Duran does not have the same KO power as N'Dou, but his wild clubbing swings are similar, and Floyd would be cool as a cucumber shoulder-rolling and embarrassing Duran, grinning that big white-gumshield grin then wobbling Duran with check-hooks off the ropes. I wouldn't be surprised if Floyd introduced Duran to Mr Ringpost the same way he did to Hatton, I can see Duran getting up groggy, spitting out pieces of turnbuckle, and holding on for dear life as Floyd forgot about defence and went for the stoppage, unloading combination after combination. 'No Mas'
