Emanuel Steward and Amir Khan.

Would Steward have been a good fit for Khan, with his speed and suspect chin? Steward has a history of training fighters with weak chins, such as Wlad and Hearns. He trained Wlad, who also had/has a glass jaw, and he has some of the best defense of any boxer today.

yes he does, the hug

Khan made money, went to america and was never the same, lack of dedication or passion, did he reach his limit.
A trainer does not make a boxers heart.

For a few months maybe. The chinny fighters that Manny has trained had one thing in common, they came to value listening over getting knocked the eff out again. Khan's problem is he doesn't listen to his trainers. He's got a habit of getting into slugfests he should be nowhere near. His hoppy kangaroo style is a lot harder to pull off on jelly legs. Heart just means you take more of a beating if you can't learn to fight smart. You can have the best trainer in the world but it doesn't amount to squat if you don't listen to him.

There are a lot of instances where a great coach and a lesser coach would give a fighter the same advice because, its fundamental (don't slug with a slugger; circle away from the power hand; don't go straight back; don't bring back your jab low; use your angles). The difference is the great coach has a reputation and a large enough cut of your paycheck that says you cant afford not to listen to him.
