Illegal Attack • Illegal Block • Over the Net • Center Line • Net Foul At The Net Ed Vesely 3/10/2012
Illegal Back Row Attack • Player is a back row player • Player is in the front zone (or has jumped from the front zone) • Ball must be entirely above the net when attacked by the offending team • The attack must be completed We most often think of…
What is a completed attack? • An attack is a ball directed towards the opponent’s court • It is completed when any of the following three happen: • The ball goes completely beyond the vertical plane of the net untouched • The ball is played by the opponents while in the vertical plane of the net • The ball is legally blocked by the opponents before it reaches the vertical plane of the net
Communication • Signal • When to Whistle • To “Safe Sign” or Not To “Safe Sign”
Challenges • Tracking players • Judging ball height • Judging foot position • Compressed timeframe: bang-bang plays
Video Examples • Attacker from the attack line (BRA-1A) • Attacker from the attack line (BRA-2A) • Tight set at the net (BRA-3) • Safe Sign?
Illegal Libero Attack • Player is the libero • Player is in ANYWHERE on the court • Ball must be entirely above the net when attacked by the libero • The attack must be completed Signal (Illegal Attack) is the same as Back Row Attack
Illegal Attack from a Libero Assist • Libero: • Is in the front zone • Plays a ball using overhead finger action (ball height at time of set doesn’t matter) • Player receiving the set: • Is ANYWHERE on the court • Attacks the ball when it is completely above the height of the net • The attack is completed • Signal Illegal Attack, then indicate libero
Illegal Attack of the Serve • Ball is served • Player is in ANYWHERE on the court • Ball must be entirely above the net when attacked by the offending team • The attack must be completed Signal (Illegal Attack) is the same as Back Row Attack
Definition of a Blocker • Player is close to the net • Player is reaching higher than the net • Player deflects a ball coming from an opponent • Completed Block: When a blocker makes contact with a ball coming from the opposition, the block is considered complete.
Illegal Back Row Block • Back row player completes a block • Block does not have to be intentional • A back row player who contacts a ball at the same time as an opponent has committed a back row block. • Faking or attempting a block is LEGAL. Only a completed block is illegal. We most often think of…
Collective Block • Two or more blockers in close proximity form a collective block. • A collective block is completed if any of the players involved in a collective block contacts the ball. • It is illegal if a back row player participates in a completed collective block.
Other Blocking Faults • Libero • All back row blocking faults apply • A libero is not allowed to attempt a block • No player may complete a block on a served ball.
Playing the ball • A player shall not contact a ball that is completely on the opponent’s side of the net unless the contact is a legal block. • A ball in the vertical plane of the net may be played by either team. This may be an attack or a block. • A blocker may not interfere with an opponent attempting to play a ball by touching that player before or during the attempt to play the ball.
Legal Block • May block a ball completely on the opposition’s side if the opponent has had the opportunity to complete its attack: • Attacking team has had its three hits • Attacking team has had the opportunity to complete its attack or directs the ball towards its opponent’s side of the net • The ball is falling near the net and no team member could make a play on the ball
Video Examples • Setter tries to save ball (BRA-4A) • Setter tries to save ball (BRB-2) • Blocking over? • Blocking over?
Center Line • A hand or foot may contact the opponents’ court beyond the center line provided some part of that hand or foot remains on or over the centerline. • Any other body part contacting the opponents’ court is a foul. • Crossing the center line outside the width of the court is legal • Interfering with an opponents’ effort to play a ball is a foul, even if the player’s position is otherwise legal.
` FOUL NO FOUL FOUL? FOUL
Net Foul • It is a foul to touch: • Any part of the entire length of the net. • Any of the net cables. • The antennas. • Exceptions: • Loose hair • Ball forces the net into the player • Interfering with an opponents’ effort to play a ball is a foul. For example, intentionally move hands to deflect a ball heading into the body of the net • Dangerous contact with standards or first referee platform
Considerations with Back Row Player with the Ball Near the Net • Is the ball completely above the net ? • Is the player above the net? • Is the ball in the vertical plane of the net? • Was the ball directed towards the opponents’ court? • Was it possible for the attacking team to make another play? • Who touched the ball first? • Now, what if the first hit was from the libero hand-setting a dig from the front zone? What changes?
