To be fair to Khan, he done the job he had to do, and done it in style, the Jew boy was caught clean and caught cold and just didn't stand a chance after the first knockdown.
Amir's clearly very strong at the weight, and his speed and punch power is developing real well. Better than that though, I think even with his dodgy chin he's still not afraid to let the punches go. You get a lot of boxers who become gun shy after getting spannered, especially in the manner he got done against Prescott.
There will be more testing fights for him in the future but he got the job done well last nigh
