The delivery
Decide inswing or outswing before you draw the players. The arrow from the corner arc should show that curve. An inswing aims at the near post. An outswing leaves the ball for a runner.
The runs
One player attacks the near post, one holds the far post, and one stays at the edge for the second ball. Too many arrows hide the screen. Name the screen in the notes if two attackers cross.
Rest defense
Leave two players near halfway. Draw them, even if they do not join the attack. The note can say who stays if you are protecting a lead.
