Calzaghe didnt have a prime, He was a class boxer with decent power in both hands. Then the hands got injured to the point he couldnt afford to land many power shots so he become more of a boxer and his talent just kept improving.

A prime Calzaghe would of had the power and the skills at their very best but the 2 never combined. Maybe they would of at some point but the hands gave in too early for that to happen.
