No doubt about it Hatton is number 1. People say Kosta Tszuyu (how the hell do you spell it anyway) and Castillo were has been fighters but I think Calzaghes only big win was over Jeff Lacy and to me he was well over hyped. Plus Hatton going over to America has to put him above Joe who only likes to fight in his own backyard. Maybe my opinion will change if Calzaghe beats Kessler!!
