Floyd Pattersom may have had a questionable chin but the guy had a huge heart. To fight Liston twice after being demolished in the first fight took guts... Liston was a scary guy.

To get knocked down 7 times in a fight means you have got back up at least 6 times... 6 times.... suspect chin yes... heart the size of a small island certainly.

Jones - got Ko'd past his best.

Khan - questionable to say the least but it's his leaky defence and inexperience that leaves his chin out to dry to take a shot flush.

So erm basically I don't know which has the worst chin
