Amir Khak & David Gaye are both glass jaw fighters. Amir Khak lost to Wullie Limond but was let off the hook with a 14 count.
Tyson took some superb shots in his prime, the only time I ever saw him hurt during his peak was when Frank Bruno (who despite his limited ability and poor stamina was a big puncher) rocked him before losing in five. Lennox Louise one of boxings biggest frauds had a glass chin and let us not forget that he took a Spent Tyson to court to prevent him having a warm up fight meaning Tyson had effectively boxed 10 rounds in 10 years so Louise deserved no credit for that 'win' what so ever. Louise wouldn't have went two rounds with Tyson in his prime. He was being given a boxing masterclass by Vitali and that fight was stopped because Vitali's eye was slashed by the inside of Lennox Louise's glove.
Clazaghe had an awesome chin despite four career visits to the canvas and Nigel Benn deserves a mention for coming off the floor to beat De Witt, Barkley & McClellan. Gatti & Ward punished each other relentlessly during their thrilling trilogy as well!
