Coaches have a ball

X1 and X2 step in to block and begin to stutter step

Defensive players must closeout when coach slaps the ball

Coaches pass to players on perimeter.

1 and 2 must be prepared to shoot 3 immediately.

X1 and X2 must turn and sprint to challenge the 3 point shots.

Offense gets a point for getting 3 point shot off and bonus point for a make

Defense gets a point for stopping shot.

Change defense to offense after a set number of shots or time.

Variation: you could have defense have to guard 1 dribble before coach passes the ball.
