If you mean has the best chance of proving they don't have a glass chin even though people say they do then there is David price who got knocked out from a shot under the ear nowhere near his chin and was also stopped prematurely but he knocked Thompson down yet nobody said Thompson has a glass chin. And there is Tyson Fury who has been knocked down by two small heavyweights but only because he stupidly walked onto shots because he took the win for granted but he doesn't actually have that bad a chin that we know of because he has taken shots off bigger punchers than Pajkic and Cunningham before.
My vote goes Amir Khan, so-called Champion Emeritus of crumble-chins. However the latest and glorious destruction of Broner by Maidana has thrown at least a little doubt on this for me. Every time Khan has been put on ***** street it's been a flush shot on the chin. It's his defence much more than his chin that's the problem for me.
The level of delusion in the bolded is ridiculous. Fury has a glass jaw, period. He was rocked by Chisora and Firtha.
