Re: "You have no evidence that Khan has a china chin..."
What happened was not china chinned. Yes he didn't look like he had a great chin but it was still 5 huge shots. Someone with a china chin gets put out for 10. What you also found out is he has survival skills, heart and the mental fortitude to turn things around in one round.
Amsterdam and Zakman are a disgrace to the sport. Both of you would be put clean out by the shots landed on guys like Harrison and Khan. Khan wasn't born with a legendary chin. In this case it is all about heart making up for it and he sure as hell showed that.
Amster you should be saying 'I'm a cock, Khan proves his heart'.
