Come on Haye isnt a Glass jaw, Carl Thompson was a world Champion beat prime Eubank more convincingly than Calzaghe.
There is a big difference between having a glass jaw, and being an aggressive fighter that lends himself to taking a big shot. Most people labeled with a glass jaw, don't have one.
Holt-Torres is a great example of what happens when two guys who can punch but can't take a punch get together.
Haye would wipe the floor with Harrison. A more even, glass-jaw matchup would be Wlad v Haye. Although I am sure Wlad wins, by KO, there is a good chance of Haye jumping on him from the off, landing a bomb or two and KO'ing him very early.
Jerome LeBanner, a K1 kickboxer is one of my favourite to watch. He's powerful, but has one of the worst glass jaws I've ever seen. Watching him fight, you've got a very high chance of seeing a KO :good
Audley doesn't have a glass jaw, he is gun shy and has no heart which is a completely different thing
