Basketball Officials Clinic3 person mechanics
3 Person Terminology
• Rotation• Switch• L Official (Lead)• C Official (Center)• T Official (Trail)• Close Down• Ball Side• Strong Side• Weak Side• Table Side• Opposite Side
• Call selection• Catalog plays
• Double Whistle Mechanics• Don’t come up with
prelim• Game Management
• Aware of time, game, score, situations
• Live Ball Communication• Patient Whistle
• Secondary Whistle• Communicating Last
Second Responsibilities
Pre-game Conference• Do not overlook this important aspect of the game• Know your partner’s name & tendencies• Discuss switching, helping with press, displacement, &
communication– Make sure to have the shooter & not to grant TO until all communication
is done
• Discuss situations (types of players & style of play)– Double whistles (foul vs. violation?)– Block/Charge– Rebounding fouls– Illegal screens– New rules (team control fouls)
• Talk about dealing with technical fouls• Discuss last minute & clock responsibilities
CAPTAIN’S MEETING & JUMP BALL PRODURES
Pre-game Positions
Jump Ball Positioning
U-1
U-2
R
R checks both officials, gets players set, blow whistle, indicate directions & tosses
U-1 checks table, counts players, check toss & chops clock; U-2 confirms with R
Ball Goes Right
Primary Areas of Coverage
C - Referee Off Ball, look for illegal screens, going through screens, displacement, holding, etc.
L – Mirror ball, referee the lane/post area: T – Get angle/position & on-ball coverage; 3 pt coverage
Lines of Responsibility
• Lead only has baseline– If doing duties and looking at primary, WILL
need help on some opposite side out of bounds
• (blow whistle with arm up & look to “C”)
• Trail has his/her sideline, midcourt line, and backcourt line (when appropriate)
• “C” has own sideline (may help with midcourt if rotating or transition)
Lines of Responsibility: T-Green, C-Yellow, L-Blue
Throw-In Responsibilities• “L” may administer throw-ins on either side of
player when staying in frontcourt• Administers all Throw-Ins below FT line extended
• May bounce ball on sideline
• “T” handles all throw-ins in the backcourt, regardless of location (“bump and run,” if necessary)
• “T” may bounce any sideline or end line throw-in (may depend on defensive pressure)
• “C” out of bounds, always have 2 officials ball side for throw in
End Line Throw-Ins in the Frontcourt
• L may administer throw-ins on either side of player when staying in frontcourt
Shot & Rebound Coverage
• Lead should not be positioned within lane lines
• Both C and T should close down on shots
• C is primarily responsible for weak side rebounding
Shot & Rebound Coverage
Three-Point Shot Coverage
• Lead should not be positioned within lane lines
• If both C and T indicate the 3-pt attempt, T should referee the defense on the shooter and stay with the shot; C should release and cover rebounding
• C/T should mirror the other official’s “good” signal
Lead help on 3pt shot
• Only on fast break will Lead Signal 3pt. Signal• Trail will still mirror 3pt. Signal
and will go up if good w/ C mirroring made basket
Lead Official Closes Down, Prepare for Rotation
ROTATION SEQUENCES
When to initiate rotation at Lead
YOU HAVE TO USE YOUR PERIPHERAL VISION AT ALL TIMES!!!!!
• The ball is below the free throw line extended (inside 3 pt. line) for an extended period of time
• If in the frontcourt (fast break) all 3 officials and the ball are in frontcourt status and the ball is weak-side – Want two people strong-side (ball-side) if possible
• The player has received the ball weak-side and …– Is definitely putting the ball into the post to a big man/woman
(Think SHAQ…)– Has consistently beaten his/her man and looks to drive a lot
• Person at 3 pt line, looking to drive baseline also
When not to rotate?
• Quick jump shots• Ball is being tossed around the arc or dribbled
around the arc without making a drive to the basket
• When all 3 officials and the ball are not in the frontcourt
• Last few seconds to quarter or half• Loose ball when no team possession is gained
– Exception: To get a better angle for a foul/jump ball• Then fix the move by going back to original position
Lead Initiates Rotation, Trail goes to New C, and C goes to New T
Responsibilities while rotating• Lead must swivel head so that he/she still can
call “old” primary area (lane area) until fully established in new position– Don’t pivot early, get to new primary the pivot finishing
rotation
• Trail & “C” must focus on primary area until Lead gets into new “Lead” position– STAY WITH COMPETITIVE MATCHUPS AS
NEEDED• Use body language so partner know you are staying with
players
Full Rotation: New Areas of Coverage
Lead has ball coverage, Trail looks off ball (screens) & fouls above shoulders on shot
Center Official referee off ball & rebound fouls
BETTER TO HAVE 2 C’S THAN 2 TRAILS
WHEN ROTATING!
DO NOT WAIVER! IF YOU’RE GONNA ROTATE..GO!!
How to fix a rotation• During frontcourt team possession
– Use verbal or non-verbal communication with fellow officials
• During change of possession (going the other way)– Easiest way to fix is for Old lead that rotated to go back to original
position and work new Trail position– If old Trail recognizes switch but new trail does not, Old lead (New
Trail) can tell official to bump up to New Lead– If old Trail does not recognize switch (may have 2 new leads),
verbally tell person to be at new C
Fixing a Unnecessary Rotation, Quick Turnover, Lead Banana Back
Trail Positioning
• Work the angles and see space– Move to improve
• Don’t get stuck too far in court– In way for transitions
When Lead helps “C” & Rotate
• Team just established frontcourt possession on “C” Side
• Player is feeling pressure or is being trapped• “C” must get angle and may need to go step
towards division line to see the players/play• Lead must recognize situation and rotate over• Trail must recognize and help at 1st then move
down to “C”• Lead should use vision to anticipate this
situation when ball crosses midcourt & sees pressure or ball settling
Center Initiates Rotation: Trap on Center Side by Mid-court
Press Coverage• Old Lead/New
Trail stay out of bounds until ball goes above FT line
• Has ballhandler & defender
• Center stays at FT line & moves w/ second wave of players
• L should have deepest player in front and boxed-in
• All officials prepare for help calls
C responsibilities in transition
• Center may have ball responsibilities on quick passes
• In any transition, can call across court to other sideline
• May have best view across paint even in front court play
Foul Reporting Mechanics
• Only 2 officials should be moving– 3rd official dead ball officiating
• Calling official freeze after call & notify players/partners situation– Report Foul & Go Opposite Table
• Hustle around players & Stop in reporting area (Federation mechanics)
– Opposite Table official go to calling official’s previous area for throw-in or prepare FT
• Do not cross vision line of reporting official
Foul Reporting Mechanics: Lead non-shooting foul on baseline
C watches all players during dead ball
Lead whistles foul, pauses, gets info &
communicates with partner
situation, points to spot
of throw-in
Center gets ball for throw-in going outside players & pointing to spot of throw-in
Trail Official watches all players during foul report
Foul Reporting Mechanics: Center non-shooting foul on baseline
Center whistles foul, pauses, gets
info & communicates
with partner situation,
points to spot of throw-in
Lead gets ball goes to opposite baseline for throw-in & point to spot of throw-in
Trail & Lead Official watches all players during foul
Center after foul report
goes back to position as Trail going opposite
table
Foul Reporting Mechanics: Trail non-shooting foul on sideline
Lead Official watches all players during foul report
After report, trail stays in position for
throw-in
Center Official watches all players during foul report & stays at same position
Trail whistles foul, pauses, gets info &
communicates w/ partners situation,
points to spot of throw-in &
goes opposite table
Foul Reporting Mechanics: Lead non-shooting foul on baseline
Foul Reporting Mechanics: C non-shooting foul on baseline
Foul Reporting: Trail calls shooting foul
Foul Reporting: Lead calls shooting foul
Foul Reporting: Center calls shooting foul
Foul Reporting: Trail calls shooting foul
Foul Reporting : Center calls shooting foul
Foul Reporting: Lead calls shooting foul
Free Throw Mechanics: Non-rebounding free throw
Trail bring in subs
Free Throw Mechanics: Rebounding free throw
Both Trail and Center step down on FT and Center chop clock, lead picks up arm to chop if made basket
Bump & Run: C calls travel on White in transition
Bump & Run: Trail calls backcourt on White in transition
No Long Switches: Lead calls player control foul on White
C Stay back to help with pressure if needed
Last Second Shot• C or T – Opposite table official is
responsible
• L may need to offer assistance or be responsible if on fast break
• Responsible official should communicate with partners that he/she has the last second shot (discussed during pre-game)
Timeout Mechanics & Positioning
On any TO, make sure to know situation & communicate w/ officials & teams
Prior to report, tell fellow officials who’s ball or who the shooter is
