Netball Drill Demonstration
The 2 defenders are only allowed in the Circle.
Attackers can move in and out of the circle as they wish but can only have one player at a time inside the circle.
Start the practice with only 1 shooter and 1 feeder.
You can build this game up over a long time and develop it with every move and interchange between the 2 attackers until it feels like your players could do this in a real match.
