How do you emphasize a rule that doesn't exist?

Since Cameron has now provided a rules basis for the interpretation perhaps the focus of this conversation should switch from should you call it (yes you should) to how it should be applied.

And if you are still on the fence about a player being disconcerted after the release, consider this: A players is stepping up to the line for his 10th free throw of the game (its been a rough one). As part of his routine he holds his follow-through for an extended period of time and remains focused until the ball hits the rim. During the first nine free throws he took a defender crosses the line and is in his space during this follow through process before the ball hits the rim. Could this disruption of the shooter's process be enough to disconcert him, causing him to adjust what he normally does and effectively taking away the advantage a free throw is supposed to award him? BTW, this would not apply to a regular shot because the same expectations for awarding the shooter an opportunity to take a shot without interference do not exist.

I can see this along with Cameron's rule reference as an argument for the POE.
