I'm not sure if anyone else posted this but Paulie fought Cotto with one hand to much better success than he had against Hatton, he landed easier, he hit less, he actually dominated the fight and didn't let Paulie turn it into a clinchfest like he did against Cotto, the reason Hatton was able to do this was because of his terrific footspeed, he could get back out in situations where Cotto couldn't, that is why IMO he was a bigger challenge for Mayweather potentially, and maybe for Pacquiao.
