Should Glass Jawed fighters be forgiven for getting ktfo a couple times?

Khan will be exposed by another jab.

Any fighter who caught a hard shotgun jab like that, right on the point of the chin, would've been hurt at least a little. I've even seen a few KO's from jabs like that over the years. Rahman broke Terrance Lewis' nose with a jab a few years ago (the punch gave him a KO win).

You've "exposed" your limited knowledge of the sport.
