Volleyball drill: passing, defending and attacking

A serves to B. B passes the ball to the playmaker, who then plays a high ball into the backfield. B defends this ball back to the playmaker, who then gives a setup for B. B attacks this setup.

After the attack, A takes B's place and B becomes a reserve. The playmaker stays.

The attackers use the left half of the court with one playmaker. The middle attackers and diagonal attackers use the right half with another playmaker.

Extension:
After the service, A takes a second ball. After B's attack A throws this ball into the field. B plays this ball to the playmaker, the playmaker gives a setup and B attacks again.
