Attack within a radius of about five metres around the basket.
All attackers may shoot.
The defenders must try to score as few goals as possible.
5 x 1 minute. After each minute turn around.
If the number is right, you can specifically train zone defence during the game: Zone defending.
The defenders let go of their opponents as soon as they get further than about six metres from the post.
The defender then has only one task: intercepting the ball by grabbing the rebound.
This also includes letting the attacker shoot from distance.
After all, if they do not shoot, they cannot catch the ball.
Instruct certain attackers to give more pressure than others.
The art of collective backfield defending is to give the pure shooters so much pressure that they prefer to leave the shot to a teammate who is as free as a bird (but who is deliberately left free by the defence because it is known that he 'can't shoot anyway').
