1. Incidental Contact
The mere fact that contact occurs does not necessarily constitute a foul. Contact which is incidental to an effort by a player to play an opponent, reach a loose ball, or perform normal defensive or offensive movements, should not be consid-ered illegal. If, however, a player attempts to play an opponent from a position where he has no reasonable chance to perform without making contact with his opponent, the responsibility is on the player in this position.

The hand is considered "part of the ball" when it is in contact with the ball. Therefore, contact on that hand by a defender while it is in contact with the ball is not illegal.

2. Guarding an Opponent
In all guarding situations, a player is entitled to any spot on the court he desires, provided he legally gets to that spot first and without contact with an opponent. If a defensive or offensive player has established a position on the floor and his opponent initiates contact that results in the dislodging of the opponent, a foul should be called IMMEDIATELY.

During all throw-ins, the defensive player(s) must be allowed to take a position between his man and the basket.

A player may continue to move after gaining a guarding position in the path of an opponent provided he is not moving directly or obliquely toward his opponent when contact occurs. A player is never permitted to move into the path of an opponent after the opponent has jumped into the air.

A player who extends a hand, forearm, shoulder, hip or leg into the path of an opponent and thereby causes contact is not considered to have a legal position in the path of an opponent.

A player is entitled to a vertical position even to the extent of holding his arms above his shoulders, as in post play or when double-teaming in pressing tactics.

Any player who conforms to the above is absolved from responsibility for any contact by an opponent which may dislodge or tend to dislodge such player from the position which he has attained and is maintaining legally. If contact occurs, the official must decide whether the contact is incidental or a foul has been committed.

3. Screening
When a player screens in front of or at the side of a stationary opponent, he may be as close as he desires providing he does not make contact. His opponent can see him and, therefore, is expected to detour around the screen.

If he screens behind a stationary opponent, the opponent must be able to take a normal step backward without contact. Because the opponent is not expected to see a screener behind him, the player screened is given latitude of movement. The defender must be given an opportunity to change direction and avoid contact with the screener.

To screen a moving opponent, the player must stop soon enough to permit his opponent to stop or change direction. The distance between the player screening and his opponent will depend upon the speed at which the players are moving.

If two opponents are moving in the same direction and path, the player who is behind is responsible for contact. The player in front may stop or slow his pace, but he may not move backward or sidewards into his opponent. The player in front may or may not have the ball. This situation assumes the two players have been moving in identically the same direction and path before contact.

4. The Dribble
If the dribbler's path is blocked, he is expected to pass or shoot; that is, he should not try to dribble by an opponent uness there is a reasonable chance of getting by without contact.
