I don't think he does, I think people overrate Khan's power since the Salita fight, he does have power but it's not anything out of this World and I don't think he's any more powerful than Hatton was. Malignaggi is seriously tough to take out, Cotto couldn't do it and Malignaggi fought him with a fractured face for most of the fight, he's only been stopped once and that was because his corner threw the towel in even though Paulie wanted to fight on. It should make an interesting fight.
im saying he was over drained. thats the point im trying to make. and if thats the last fight he had at 140 then its a possible indication that cotto did not want to over drain to 140 again.
His performance against Malignaggi didn't look like that of someone that was over drained, it made sense for him to move up as there were better fights for him at welterweight and it was a more comfortable weight for him to fight in. That doesn't take anything away from Malignaggi's chin in the fight between the two of them as he took a beating.
