Depends on weather you count KD's or only full fledged KD's that become 10 counts. Depends on whether you think KD's and KO's are more reflective of poor chins or lapses in defense and concentration. Patterson has been listed, but never recieved a 10 count and continually rose again...poor chin, great heart??? Most people will call out those they are not a fan of and justify those they are...pretty pointless thread in that light.
i wouldn't say amir got a glass jaw... he took some shots from maidana and peterson and survived. idk tho.. we'll see. maybe he does have a glass jaw.. maybe he's just knockout prone.. but that last knockout was a glass neck.. not a glass jaw.
