after his match against ray mercer, tommy morrison's chin had the strength of a christas tree glass ornament!
Bob Satterfield, won and lost to Harold Johnson, won and lost to Lee Olma, KOed Cleveland Williams, beat Nino Valdes, lost to Ezzard Charles, Jake Lamotta, Joey Maxium, Archie Moore, Rex Layne. Scored 35 KOs in 50 wins, lost 25, was KOed 13 times.. Cleveland Williams was 35-1 when Satterfield KOed him. He fought a ton of really good fighters.
I included him due to the manner in which he lost to the punchers. He was wiped out easily and brutally by multiple punchers. Shavers being a C plus fighter. Getting KO'd by such huge punchers does not necessarily mean you are glasses jawed but he was wiped out.
Mostly from flash knockdowns. Tito was never severely hurt or deleted from the earth like Khan was multiple times in his career. Khan got heart but his chin is sensitive to punches that dont even land that flush. Tito got hit from flash knockdown and got back up to dominate the fight. It actually made him sharper in later rounds because he picked up his defense. Amir Khan chin is made in China and will be known for him getting knocked out than actually knocking out fighters. He was never world class, just a solid contender. Tito genuinely dominated 147.
I think we are giving the term "Glass chin" too wide a scope. If Marquez has a glass chin then almost everyone has a glass chin. I mean are we really going to rank his chin, which took countless hard lefts from Manny Pacquiao and other punchers like Katsidis to Amir Khan who was brutally KO'ed by Briedis Prescott? One left hand from Pac would spark Khan clean out. Personally I define a glass chin as being a fighter who can be hurt, dropped or stopped even by guys who are not noted punchers. Being sparked out by a Thomas Hearns, Mike Tyson, Hamed, Julian Jackson, David Tua etc, doesn't mean you have a glass chin, it just means you got hit by a fighter who was a huge puncher and only granite chins can take shots from punchers like that and sometimes even the granite chins crack if hit enough times.
