Screen Blocking Fundamentals
ARTICLE 2. A player who screen blocks shall not do any of the following:
a. Take a position closer than a normal step when behind a stationary opponent.
b. Make contact when assuming a position at the side or in front of a stationary opponent.
c. Take a position so close to a moving opponent that their opponent cannot avoid contact by stopping or changing direction. The speed of the player to be screened will determine where the screener may take their stationary position. This position will vary and may be 1 to 2 normal steps or strides from the opponent.
d. After assuming their legal screening position, move to maintain it, unless they move in the same direction and path as their opponent.
