From recently revised version of "Most Misunderstood Rules": When an airborne player keeps control of an attempted shot that is blocked and is unable to release the ball and returns to the floor with it, that player has not traveled; it is a held ball. If, in this situation, the shooter loses control of the ball because of the block, then this is simply a blocked shot and play continues. If, in this situation, the defender simply touches the ball, and the airborne shooter returns to the floor holding the ball, it’s a traveling violation. When an airborne player tries for goal, sees that the try will be blocked, purposely drops the ball, and picks up the ball after it hits the floor, that player has traveled by starting a dribble with the pivot foot off the floor.
