I give them both a decent shot, just because of their styles, but I would go with Cotto, he hits harder, and is a better overall boxer.
Definately Cotto. Hatton can't beat Mayweather at any weight. I think Mayweather would beat Cotto too. However, Cotto has alot of heart and more boxing skills than Hatton. Cotto depends too much on his left and gets hit too easily, which is why I don't think he can beat Mayeather. However, he has a better shot than Hatton.
Neither. Hatton's style doesnt fit fighting a fighter like Mayweather. And Cotto gets hit too much. If I had to choose, Id say Cotto. His body attack (which has bothered Floyd in the past) is top notch. And he is relentless. Unfortunately, I see them both getting beat. Best chances to beat Floyd are Mosely (fast, good defense, attacks the body well and has a great jab), Simms (you will see why after tonight...boxings best kept secret) & Winky if he could still handle the weight....which is a HUGE IF after going up that far to fight Hopkins.
Cotto i think has the better chance. He has the better skill set, but I still don't think he would beat him.
I think Margarito will beat Williams. But I think a guy like Williams has the tools to beat PBF. Volume punching and such length that it negates PBF's speed.
Simms at 154. Of those two, Cotto. Of course, I'll look like a jackass if Simms loses to Alcine in a few minutes.
To answer the question Cotto. A fight between Floyd and either Hatton or Cotto would take place at 147 and IMO Hatton would be out of his comfort zone. Mosely would be a good choice if he hasnt gotten old overnight (it happens sometimes). I do think that Mosely has slowed down enough for Floyd to beat him.
It isnt even debateable.. Cotto of course would give Mayweather way more problems.. Mayweather beats Hatton EASILY.. I can't wait for them to fight
