Khan's chin is also awful. People don't realise that I'm agreeing Bailey hits hard, just not as hard as people are saying.
Bailey's power is only PART of the equation to KO'ing guys with nearly abysmal punch volume. The man has damn near perfect timing and accuracy. It's the combination of the three that makes him one of the most dangerous guys in the game. It doesnt reflect so much on Jones' chin, but moreso this blend of tools put together.
