A moving screen is not in and of itself a foul; illegal contact must occur for a foul to be called. If a blind screen is set on a stationary defender, the defender must be given one normal step to change direction, and attempt to avoid contact. If a screen is set on a moving defender, the defender gets a minimum of one step, and a maximum of two steps, depending on the speed, and distance of the defender. Players setting screens must have both feet inbounds.

It is legal use of hands to accidentally hit the hand of the opponent when it is in contact with the ball. This includes holding, dribbling, passing, or even during a shot attempt. Striking a ball handler, or a shooter, on that player's hand (in contact with the ball) that is incidental to an attempt to play the ball is not a foul.

Reaching in is not a foul. There must be illegal contact to have a foul. The mere act of reaching in is, by itself, nothing. If illegal contact does occur, it’s probably a holding foul, an illegal use of hands foul, or a hand check foul. When a player, in order to stop the clock, does not make a legitimate play for the ball, holds, pushes, or grabs away from the ball, or uses undue roughness, the foul is an intentional foul.

The following acts constitute a foul when committed against a ball handler. This would include a player in a post position: Placing two hands on the player; placing an extended arm bar on the player; placing and keeping a hand on the player; contacting the player more than once with the same hand or alternating hands.

Over the back is not a foul. There must be illegal contact to have a foul. A taller player may often be able to get a rebound over a shorter player, even if the shorter player has good rebounding position. If the shorter player is displaced, then a pushing foul must be called. A rebounding player, with an inside position, while boxing out, is not allowed to push back, or displace, an opponent, which is a pushing foul.

A defensive player does not have to remain stationary to take a charge. A defender may turn away, or duck, to absorb contact, provided the defender has already established legal guarding position, which is both feet on the playing court, and facing the opponent. The defender can always move backwards, or sideways, to maintain a legal guarding position, and may even have one or both feet off the floor when contact occurs. That player may legally rise vertically. If the defender is moving forward, then the contact is caused by the defender, which is a blocking foul. If the opponent with the ball is airborne, the defender must have obtained legal position before the opponent left the floor.

The mere fact that contact occurs does not constitute a foul. Incidental contact is contact with an opponent which is permitted and does not constitute a foul. Contact, which occurs unintentionally in an effort by an opponent to reach a loose ball, or contact which may result when opponents are in equally favorable positions to perform normal defensive, or offensive moves, should not be considered illegal, even though the contact may be severe. Contact which does not hinder an opponent from participating in normal defensive, or offensive, movements should be considered incidental.
