Another way to look at it: A pass cannot be a violation. If a player throws what starts out to be a pass, then goes and gets it himself, it can become a dribble, which may or may not be a violation, depending on whether his dribble is gone.

If a player has used his dribble, then forgets and pushes it to the floor in an apparent start to another dribble, it is a violation when it hits the floor. If he remembers and runs away from it at this point, it's still a violation.
