I've seen shooters hit on their arm, pulled down, and hit the deck pretty hard. That would be more an intentional or flagrant foul I guess. Part of my thinking comes from being told (or assuming) that any contact during the process of the shot, including after the release, is a foul. I'm going to check the rulebook to see what it says. I understand the advantage/disadvantage philosophy of it though.
