Khan under Steward.

[Master]

I think khan would have gone to Steward after he left Roach has Manny not been ill. Steward knew how to get the best out of tall skilled boxers.

Not sure about Naz but his current trainer Virgil is an ideal fit because he is calm and methodical utilising Khan's advantages.

[SlimTrae]

Manny Steward was a gift to the fighter with reach: hearns Lewis , Klitchko.

Khan imo would've benefited.
Side note: Jermaine Taylor never should've went to Manny, bad choice.
