3 sets up deep and 2 is up near the shooter on the left side. When the official hands the ball to the shooter 2 takes off deep to the right side where he spots up. When the shot is made, 4 takes the ball out of bounds and inbounds to 3 coming up the sideline and across the half court line. Then 3 passes to the point guard sprinting up the floor who looks for 2 spotting up. 2 looks for the shot or drive.
