He was dominate under 140lb no question but above that he has certainly been picking easier options hence these questions always comming up. Even fighting Hatton at 147 is ridiculous when there are more legitimate Welterweights such as Moseley and Cotto, and even Williams. Fighting Hatton at 140lb would have helped his legacy since he beat the man who he avoided, but fighting Hatton does very little for his claim to be the greatest ever!
