In Netball a team consists of of seven players., some of the position names may have changed since, but in my day they were: centre, centre attack, centre defence, attack, defence, shooter and goalkeeper. Only attack and shooter could score goals, attack and shooter couldn't cross the line into the opponents attack zone and the goalkeeper and defence cannot cross into their opponents defence zone. centre attckand defence can move anywhere on the court and I think centre can too. No-one is allowed to movetheir feet while holding the ball.

I hope this makes sense,
