I think the whole "glass jaw" discussion among boxing fans is usually a complete waste of time, marred by uneducated opinions and knee-jerk reactions after a KO loss.

Lennox Lewis always comes up. The guy was knocked out twice, once by Rahman and once by McCall. These are two fighters with BIG KO power, who caught Lennox with bombs he didn't see coming. I think people look at the fact that he got KO'd by two vastly inferior fighters and assume he had a glass jaw. These guys were inferior, but they were huge bangers who landed hard, right on the button. How many other times have we seen Lennox hit the deck?

People who say Floyd has a glass jaw must have only seen 2 or 3 of his fights. The guy has been tagged hard before, and in 12 years of fighting pro has never been down from a punch. He avoids punches because he has the means to, if guys like Arturo Gatti and Mickey Ward had the skill Floyd has, do you think they would have taken all those punches to the head still?
