none are graced with a certain attribute that makes a great fighter.

[Nameless]

My point was they all made the best of their abilitys and none of the three relied on a certain skill to get the job done in a fight.

Disagree, for example, Calzaghe was throwing a tremendous amount of punches for a guy of his size, relying on incredible handspeed and great endurance, I think that these 2 attributes are part of what makes a boxer great or not. He also showed a very good heart, getting up from a solid knocked down against Both Roy Jones and Hopkins to come forward and nods the victory.
Kessler has an impeccable technique, solid chin and a heavy load of power in his gloves, I think that being able to have a great technique, a solid chin and power are as well ingredients to build up a champion.

Why does a fighter need a 'certain attribute'? what does that even mean?


isn't beating the best and proving yourself over and over the test, or must you also develop a Mike Tyson Punch Out cartoon style uppercut to be considered great ?
