The problem comparing Hatton with Calzaghe is their ages, divisions and Calzaghe got his best win late in his career whilst Hattons came in his pomp. Actually their wins are pretty similar but in reverse situations.

Calzaghe's been THE BEST in a poor supermiddle division for years. Only recently the Lacys and Kesslers turned up as worthy, exciting challengers. Remember, he was meant to leave SM a few years ago - How many times did he get injured before the proposed Glen Johnson fight again? 50? 60?

Hatton, on the other hand, was one of the lesser lights in his division before pulling off the brilliant upset win over Kostya.

I rate Calzaghe no. 1 through longevity if anything

But should Hatton beat Castillo he'll definetly go no. 1....probably nothing Calzaghe could do to surpass him on the all time lists either.
