Rocky Marciano down only twice both off balance shots. Marvin Hagler down only once and that was an off balance shot. James Toney, David Tua and George Chuvalo had iron jaws to.
I remember during Jose Torres-Eddie Cotton, Carlos Ortiz was a guest commentator and said low blows aren't very painful. This goes against my own beliefs, as I've been hit in the groin in plenty of different settings and they hurt every time. Who had the strongest groin?
Brewster and McCall...McCall still owns. However, somehow that damned Helenius tore Brewster apart, was surprised to see that . His jaw got worse over time.
I think his chin was broken after the Kessler and first Bute fight. I don't believe he can take punches like he could. His chin against Kessler, though, was a wonder to behold. He was getting his **** knocked around like his neck was made of rubber. Took flush power punches in combination directly to the point of the chin from a guy who can really punch and was never really badly hurt from what I recall.
Zeijko Mavrovic. Look at the bombs to the head he takes from Lennox ****ing Lewis of all people and stays on his feet. Lennox landed his patented "hold the neck with the left and bomb him with the right uppercut" numerous times. [ame]http://www.youtube.com/watch?v=nzlMpejdyeQ[/ame]
