3-Person Mechanics

Terminology Rotation Switch Lead Official Center Official Trail Official Close Down Ball Side Strong Side Weak Side Table Side

Rotation Usually initiated by Lead official Rotation refers to a live ball situation Location of ball keys a change in coverage Lead moves to ball side and Trail is pulled down to Center and Center is pushed out to Trail Exception: Center can initiate rotation if they “read” trap when ball swings to their side

Switch Switch is a dead ball situation Caused by official who called foul or violation After reporting a four or violation there may be a change in position 2004-05 change – Official who called foul moves to table side as Trail (one exception)

Court Positions Lead Official is positioned at the end line Lead maintains good depth OFF end line, NEVER in paint area, strong/ball side Center Official is the outside off-ball official midway between a step below the free-throw line extended and the top of the circle Center is weak side, free-throw line extended Trail Official is the official nearest the division line. In transition, Trail becomes new Lead Trail is strong side, top of 3-point Arc

Miscellaneous Close down – official(s) movement (can be one or two steps) on movement of the ball Trail moves toward end line Center can move slightly to get better rebounding angles Lead moves toward nearest lane line extended These movement especially for outside officials prevents them from bailing out and not being in position to officiate the defense.

Miscellaneous cont’d Ball side is location of the ball in a “normal” frontcourt alignment How – divide the court down the middle length wise, end line to end line, The side of the court where ball is located is ball side Ball side is usually strong side and is determined by, a) location of official who is, b) reacting to location of ball These movement especially for outside officials prevents them from bailing out and not being in position to officiate the defense.

Miscellaneous cont’d Weak side is the side opposite the Lead Official Typically occupied by Center official Table side refers to side of court where Scorers and Timers Table is located Opposite refers to side opposite Table These movement especially for outside officials prevents them from bailing out and not being in position to officiate the defense.

Pre Game & Jump Ball Pre-Game Position Jump Ball Position U1 has home team U2 has visiting team Jump Ball Position U1 chops clock and has the jumpers U2 has the eight non-jumpers Movement After The Tip R always winds up as Trail Direction & Arrow T/C opposite table responsible for arrow

Pre-game Positions U1 HOME TEAM BENCH R U2 VISITORS TEAM BENCH Note that in your pre-game alignment you are “watching” your respective teams warm-up OPPOSITE from their bench U1 R U2

JUMP BALL POSITIONS HOME BENCH VISITORS BENCH U1 R U2 U1 will be approx 28’ from nearest endline U2 will be 28’ from nearest endline

WHEN BALL GOES RIGHT VISITORS BENCH HOME BENCH U1 C R L T U2 R holds position until direction of ball is established

WHEN BALL GOES LEFT VISITORS BENCH HOME BENCH U1 T L R C U2 Hold Have clock awareness Lead MUST always be prepared to rule on quick 3-point attempt

Primary coverage area Primary Floor coverage Designated Throw-ins 3-point area of responsibility

PRIMARY FULL COURT RESPONSIBILITY VISITOR BENCH HOME BENCH T L T has side line & entire end line on other side* L has entire end line C Each official MUST be aware of these primary coverage areas. T has their sideline and opposite end line. C has their sideline only L has the entire end line in backcourt C has their sideline

PRIMARY FRONT COURT RESPONSIBILITY VISITOR BENCH HOME BENCH T L T has division line & their sideline L has entire endline C Each official MUST be aware of these primary coverage areas.

T (in frontcourt) has division line and their sideline. C has their sideline only L has the entire endline L has “paint” (green lines) and inside 3-point arc in front of L C is responsible for red area

Ball goes OOB anywhere in this area, throw-in is at end line. ENDLINE VS SIDELINE DESIGNATED SPOT THROW-INS VISITOR BENCH HOME BENCH L Ball goes OOB anywhere in this area, throw-in is at end line. Ball goes OOB on this side of paint extended, do NOT bring ball back. L to switch. Ball goes OOB on sideline, throw-in is from sideline Ball goes OOB anywhere in this area, throw-in is at end line.

THREE POINT TRY – AREAS OF RESPONSIBILITY VISITOR BENCH HOME BENCH T has 60% of coverage T L C has 40% of floor C Covering official gives INITIAL signal. Covering official signals successful. If Trail signals, Center mirrors. If Center signals, Trail mirrors. Lead has responsibility to assist Center and Trail in transition

Ball Coverage Front court rotations Shot and rebound coverage Transition coverage Press coverage

Rotation of Officials as Ball Moves From One Side To Another Ball will move from Position 1 to Position 3. C3 T1 L1 Initial Position L2 Close down EXCEPTIONS: Quick shot/drive to basket PRIMARY official has P & B ALL the way to basket Rotation completed L3 T3 C1 T 2 C – that official picks up new primary coverage off the ball L must officiate players in the post, even while moving. Keep head on a swivel. In MOST cases L moves to ball side NEVER have 2 Trails. There can be Two C’s for a brief period of time The ball keys the rotation. As a guideline and depending on playing action, the Lead should close down and may move laterally to ball side when the ball penetrates the free throw lane line extended nearest the Center.When the Lead rotates the Trail and Center Also rotate positions.

Rotation of Officials as Ball Moves From One Side To Another EXCEPTIONS: Quick shot or drive to the basket. When a player with the ball starts a drive to the basket from an official’s PRIMARY AREA, that official has the player and the ball all the way to the basket. When the Trail rotates to Center, that official picks up new primary coverage off the ball. Lead must officiate players in the post, even while moving across the lane. In most situations, Lead moves to ball side. Note: There should never be two Trails. There may be two Centers for brief periods of time.

Basic Shot and Rebound Coverage Location Trail responsible for all shots in foul-line half circle. L T Center helps Trail with shots from foul line half circle on Center’s side.

Shot and Rebound Coverage From Lead’s Left Area Center has interference and goaltending, then weak-side rebound. Weak Side Lead has shooter and strong-side rebound. Perimeter Rebound Shot Location Strong side L T Trail has interference and goaltending, then perimeter rebound.

Once in front court L is working outside in COVERAGE ON “NORMAL” TRANSITIONS TEAM BENCH TEAM BENCH C C T L L T T sprints to L to end line and works plays as it comes to them C remains C and moves w/speed of ball & players, responsible for F & V between top of circle in BC & top of circle in FC. On passes normally stay with passer. Lead takes ball responsible if ball goes to basket on your side. L to T moves to cover backside of FB or maintains pace that allows them to trail the play coming up court Once in front court L is working outside in

COVERAGE ON FAST BREAKS/TRANSITIONS TEAM BENCH TEAM BENCH C C L T L T T sprints to end line and cuts floor at about a 45 degree angle in order to get in position. This would be the ONLY time that L should be a the lane line extended. C remains C and moves w/speed of ball & players, responsible for F & V between top of circle in BC & top of circle in FC. On passes normally stay with passer. Lead takes ball responsible if ball goes to basket on your side. L to T moves to cover backside of FB or maintains pace that allows them to trail the play coming up court In this transition, L can go to lane line extended in order to be ready to officiate the play and if need be to rotate across

PRESS COVERAGE – ALL PLAYERS IN BACKCOURT TEAM BENCH TEAM BENCH T 12 D T L L Keep congested area covered with wide triangle. 4 D D 10 24 D D 32 C C Ball is being inbounded from OOB. NEVER bail out as C. Remember this becomes a 2-man game between you and L/T T/L should be as deep as deepest players New Trail has 10 second count in backcourt, remain with play action possibility of a quick turnover.
