Ricky hatton in his heyday had a solid chin. you dont take kostya tsyzu's shots and not have a great chin! wayne mccullough what british fighters really lack is good defense. you get fighters from all over getting knocked out- best example in combat sports i can think of is Mark Hunt. this samoan guy has a chin ala david tua. he's taken flush punches from big punchers and not blinked (at heavyweight) he took head kicks (several) of mirko cro cop and won the fight. he took massive punishment to head and body from jerome lebanner and won (at heavyweight) then he gets ko'd in 18 seconds by a middle - punches. so you can never tell. its easy to label a nation as glass jaws but every nation had their tough un's and weak ones. american - roy jones jr, hasim rahman, tommy morrison, gerry cooney jorge linares (south america) just to name a few dont exactly take the best shots
