well yes calderon was/is a great fighter, what i mean is look at the first fight with cazares (sp?) he slowed in the second half of the fight and got hit with shots he wouldnt have a few years earlier,

for a 108 lb fighter 33 is very old and its a testement to his skills that he is still going so strong

i really am just stretching out what 'past their best' actually means, for example Hatton will never have another tszyu type performance imo so he can be classed as past his best

Hopkins is the real star of the list though as you could argue that the pavlik fight was his best ever performance and even if not his other great performance (tito) was when he was about 36,37
