Around the hitter
Two players cover just behind the attacker, low and close. One stays deeper. Draw those three spots for a left-side attack first. The setter is often one of the close cover players.
The block touch
A ball off the block comes back fast and short. The arrow from the hitter should stop at the block, and a short arrow should return to the cover. That return is the point of the diagram.
Other pins
A right-side attack and a middle attack need their own pictures. Duplicate this play and move the cover. Do not draw all three attacks on one court.
