Explosiveness has never been Khan's problem. He has mad skills and athletic ability, it's the way he fights that is the problem. He's far too reckless, impatient and just generally rushes everything. He's always trying to be the flashiest mofo ever. If he just took his time a bit more and fought a little bit more conservatively I think this would make his weak chin less of a flaw. But like Scar said, they all look explosive in training promo clips, that the whole idea of them.
