The five spots
Two defenders start at the elbows or the slots. Three defenders protect the lane and the short corners. Place the offense outside first, then add the ball, so the overload is visible.
Where the ball goes
A skip pass from one wing to the other moves the top of the zone. Draw that arrow over the top, then a pass into the short corner or the high post. Those two catches are the usual holes.
How you attack it
Write whether the post flashes middle or the wing drives the gap. Save a second copy if you also want to show how your own 2-3 shifts.
