stupid 3 to compare.

1. RJJ didnt have a dodgy chin at all , it was late in his career , and after he had shed lots of weight , that he got KOED.

2. Patterson was a small guy fighting in a division were he was often up againest guys 2 stone heavier than him , Liston was a big puncher from instance , who could well have KOED lots of champions for other era's.

3. Amir Khan is a hyped fighter , Prescott also is a novice in world terms , we will have to see how good Prescott turns out to be , but i dont think he is that special or has the power at the top his record suggests.
Simple fact is , like it or not , Khan was floored by Limond a guy with 1 stoppage win in his 19 wins. This was a warning sign , and myself like many others on here , said as soon as Khan fights a guy with a good chin and power he will get KOED. Well he did and as far as im concernd he has a glass jaw and will be KOED each time he fights at the very top.

KHAN IS THE ANSWER TO THE QUESTION. ( GLASS JAW ).
