Why is it some boxers are feather fisted?

[Cleto_Reyes]

Might be a simple answer but I mean the guys train how to punch for most of their lives and they still cant hit hard, guys like Sergio mora , Paulie malignaggi. Is it because a puncher really is born not made?

what? the Latin Snake packs a punch.

George Foreman was an arm puncher.

What I wonder is how can guys like Timothy Bradley and Steve Cunningham not knock out guys more frequently and are relatively weak punchers? If you look at their physique, like arms, biceps, forearms, shoulders, you would think they are about to knock some one's head off in the first round. But no, these guys are featherfisted.
