Outside players have extra balls It could be 4v4 or 2v2, but never more than 4.
Coach serves ball in and players try to score.
If ball is going out of bounds the outside players keep it in by playing it to an open space. This makes the game players work hard to gain control before it goes out. NO playing it to buddies. Must win to get out of the cage, so the losing team keeps playing. Make games quick - 5 minutes.
