Team A, while in possession of the ball in its frontcourt:
(a) positions four players parallel with the sideline and they pass the ball from one to another with their arms reaching beyond the sideline plane; or
(b) has four teammates surround dribbler A1. In both
(b), the opponents are unable to get close to the ball.
This is considered to be a closely-guarded situation and a violation in five seconds in both
(b), if any B player is within 6 feet of the ball or within 6 feet of the screening teammates and is attempting to gain control of the ball. Preventing opponents from getting to the ball by using screening teammates becomes a violation in five seconds if the opponents are attempting to gain control.
