Netball Drill Demonstration
In this game you have two attackers who are passing the ball between them with one defender who stands behind the attacker. The defender is the worker in this drill.
The defending player should be constantly working, rotating around the GS using the snake-bite action.
To start with the purpose of this movement is purely to distract the GS, with the defending players moving in front of the receiving player even when the ball is at the other end of the court.
After a few goes each the defensive players can then begin to start contesting for the ball, trying to intercept the pass before it reaches the GS.
