Boxing has its share of fighters that are hard to place and even harder to predict in H2H battles. These are fighters that have some flaw or weakness that makes them beatable, but have a strength that is so overwhelming that its hard to overcome them. Glass cannons are fighters that have overwhelming speed, power and combinations that would seem to be the next great thing until they get exposed at some point. Hence the name glass cannon. When they get exposed they crumble like a glass pane up against a rock. Tommy Morrison is one such fighter. Could beat anyone but not an ATG Tommy Hearns could be considered-- Yeah, ATG indeed, but his chin lets him down. Ken Norton another. Again, Chin. But great boxer/puncher Who are some others?
How about Mark Breland? The second coming of SRR, SRL and Superman combined....then along came Moochie.
If we're talking about chins, then let's add Tony Mundine to the list. He was coming on like a force of nature back in '72-'74. Indeed, the magazines at the time had him replacing Carlos Monzon when they would eventually meet and many had Monzon ducking him at this time. Until Tony met Bennie Briscoe. Man, the scribes circling the Mundine wagons scattered after the chin was exposed. I'm sure there were similar things written about Bob Satterfield in the '50s until his weakness was exposed as well.
We had a local glass cannon in the form of Johnny du Plooy. The KO Kid could really bang when he sat down on his punches but he didn't fancy the incoming too much. He had some wins over decent names - Bey, Tillis, Pritchard and Weaver and his destruction of Broad has a OMG highlight reel finish. But the cracks in his glass heart were apparent even against Bey. The round before he knocked Bey out he wanted to quit and it was his dad that implored him to just circle and stay in the fight. Against Coetzer and Damiani he started well but folded once the going got rough. The final nail in the coffin was his match with a green Corrie Sanders, which was like the shootout at the OK Corral ... while it lasted.
Norton wasn't so much chinny has he had major problems with come forward punchers. It was more of a stylistic disadvantage.
I would nominate Wladimir Klitschko as a Glass Cannon. You know he is beatable, You just know it. If you just get to him.
Frank Bruno .hurtful pole like jab real one punch power good boxer in great condition.but there always a chance his chin lets him down or he runs out of steam.
I'm going to say King Hippo. He seemed all but invincible until it was found that when he dropped his guard he was extremely vulnerable to body shots right on the button.
Junior Jones was a lethal fighter with plenty of ability, but very poor durability. "Dangerous" Don Lee was a huge puncher who was really a kill or be killed sort of fighter.
