Hatton would not do well at WW. I don't think there is 1 elite WW Hatton can stay with, not 1. The first time he moved up he was given a gift win againt Callazo. I had him losing that fight. A fight with Cotto would be very entertaining while it lasts but it would end badly for Hatton. I think he would be target pratice for PBF because PBF is too fast and accurate for Hatton. Margarito is too big and can take a punch well. SSM too fast and powerful. If he were to move up they would probably put him in with Clottey and he would probably lose that fight. He knows he is not ready for WW which is why he moved back down.
Although Hatton did look good, JLC did look like a shot fighter. His legs were wobbly from the first bell. I'm not taking anyway away from Hatton, i think he gives EVERYBODY at 147 problems except for Mosley and Cotto.
