This detail can be used against an opponent, who is very focused at the ball and the attackers.
The team is attacking and the coach calls a player to the side line to "give some instructions".
After a short while the attackers put in a pressure on the opposite side of the court in order to pull the defenders to that side.
Also CB moves a little bit to the side. The attacking RW must be free all the time and should not receive the ball during this..
When the defense is pulled well to the side, the attacking RW can receive the ball.
RW pass the ball to nearest backcourt player which is the signal to the coach to send in his player.
CB runs forward and puts a screening on the outer side of the defense.
The backcourt player makes a long pass to the "coach"-player who now should have a great area to perform the shot.
This method can also be used in a 2-minutes suspension.
If the team has the ball and there is about 10 seconds left of the suspension time, the same pressure can be made on the defense and the suspended player is sent in when the time is ready (even if it is with a couple of seconds overtime)
