I think people overlook the fact that Khan gets hit waaay to much. He's honestly a very good offensive fighter, definitely his best asset and he even boxes pretty well behind the jab but if you are going to box like that, you can't get hit that much. He gets hit a lot and it's been throughout his whole career that it's been that way. He just isn't that good defensively and I think his defense is a bigger flaw then his chin.People make him seem like Mayweather with a fragile chin, he gets hit a lot. That and the chin don't make a good combo, especially for someone who is at times reckless in his attack in the ring.

If he fights Bradley, it won't be 1 punch that ices him, he will get tagged cleanly and consistently and might not even go down. He'll be lauded for his toughness but he will have eaten to many shots. It won't be the chin, it'll be the defense that fails.
