Volleyball drill: butterfly variation

Some variations on the well known butterfly...:

• Service-pass-catch on SU-position, running after the ball.
• As everyone is chasing his/her ball, each player has a different task, but if desired, a player can have a fixed position.
• Variation 1:
  • The SU plays a set-up to position 4, where an attacker stands to play a (placed) attack on the receiver.
  • The rotation then becomes: Service -passer -upper - attacker - off-side - service etc.
• Variation 2:
  • the fixed SU plays a ball to a receiver 'somewhere' in the field, who makes himself known by calling 'here'.
  • The SU learns to react on sound, the receiver learns to communicate his position.
• Variation 3:
  • The fixed SU plays the pass backwards to position 2, where the receiver, after an attacking movement, catches the ball and starts serving.
