I share the same concern as GAME. Khan seemed to settling into an effective style and sitting down more on his punches. A new trainer would have to be careful not to try and re-invent the wheel with Khan but rather build on what he's got.

There are still flaws though... Khan still gets caught with he right a lot so maybe a new trainer with a fresh outlook can iron out some of the flaws. I just hope the change has been brought about for improvement and not any reasons of arrogance.
