Reading the setter
The middle starts in front of the net and moves when the set leaves the setter’s hands. Show two possible commits: to the left pin and to the right pin. Use one solid arrow for the choice you want and a light one for the fake.
The pin blocker
The outside or opposite blocker sets the line or the angle. Mark which shoulder is open. If both blockers close the line, say so in the notes.
The defense behind
The players in zones 1, 6 and 5 move with the block. Draw the digger who takes the tip over the block. A block diagram without the floor defense is only half the play.
