Inoue. He absorbed 3 hellacious nukes from Nonito that would have flattened anyone 122 and below. Didn't go down and took seconds to recover. GGG. Clenelo.
I'd argue that the ability to get back up after multiple knockdowns is more reliant on ones conditioning, rather than their chin. Taking a punch and staying up is more reliant on a chin.
The tiny minority of fighters who've fought at the top level against many punchers and have never been dropped aren't ''iron-chinned'' they're anomaly freaks.
The art of not being hit is more impressive. Joyce is my chin pick but that's in part because he's not hard to find so it's not always a plus.
The definition? Is when your name is George Foreman "The old" and you can get bunches of consecutive clear punches in the face by fighters much younger than you like Moorer, Holyfield, Morrison or Briggs and you dont go down.
This. This right here. Beat me to it. Was gna say if you want a definition of iron chin, look up Ruslan Provodnikov.
I've seen you say this before and I'm not sure if you are being sarcastic or not. Two guys come to mind when talking about chins from that region, Steve Collins and Ricky Burns (Irish and Scottish). You have Wayne McCollugh (Irish). But the Brits, you have Ricky Hatton (flattened by Pac in 2 rounds), Frank Bruno (I think all his losses were by KO), and David Price (definition of having a glass chin).
