Well the thing is unlike years ago ko's and knockdowns are regarded as disasters these days.Until he fights someone of just even moderate power we'll still question Khan.However against Prescott he stuck his chin right out and got badly ko'd.With his improved defence he may well take counts,but they may well not be the devastating type of the Prescott fight it doesn't neccesarily have to be the end of the world,he can still win fights from there.
