Obviously inspired by the Andy Ruiz win over Anthony Joshua, I was intrigued by the how that shot behind the ear left Joshua unable to recover. So I took a trip down memory Lane to see if any of the noted iron chinned boxers from history also had an off switch. Surely every boxer has an area or a spot somewhere around his head that switches him off when hit by an opponent with a solid blow! That spot might be small or large leading to the fighter being labelled as ‘glass jawed’ or ‘iron chinned’. I know the musculature of the neck and traps can help and I know fatigue also plays it’s part as does being caught cold early in the fight so I’m not suggesting it’s all down to chin. So looking back at solid chinned fighters who got decked by one punch I came up with a Cooper Vs Ali Pep Vs Robinson Rahman Vs Lewis Hagler Vs Duran Shavers Vs Holmes McCallum Vs Curry Marquez vs Paquiao Hagler Vs Hearns Marciano Vs Walcott Benn Vs Barkley Any others or can you add a fighter who just never looked like being buzzed even when hit with bombs?
100% - a great one punch, or numerous clean punches will knock anyone out regardless of the chin. If Canelo landed that shot he KTFO Khan with on say Crawford/Spence (yes them two, they're both weight bullys, even Crawford is big for welterweight - okay sidetracking) they'd be sleeping too.
Mike Tyson took big hits from all angles, only got stopped when tired/beaten down and dominated for several rounds
