Jump Ball Positioning
Ball Goes Right
L – Mirror ball, referee the lane/post area: T – Get
angle/position & on-ball coverage; 3 pt coverage
C - Referee Off Ball, look for illegal screens, going
through screens, displacement, holding, etc.
Primary Areas of 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
ROTATION SEQUENCES
Lead Official Closes Down, Prepare for Rotation
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
Lead has ball coverage, Trail looks off ball
(screens) & fouls above shoulders on shot
Center Official referee off ball & rebound fouls
Full Rotation: New Areas of Coverage
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 the “C” can facilitate rotation
• 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 “High” to see the
players/play
• Lead must recognize situation and rotate over
• Trail must recognize and help at 1st then move down to “C”
• Only use when appropriate and this may be missed by the Lead and
Trail (be aware of situation)
• The T or C can facilitate a rotation, but ONLY the L initiates a
rotation
• A rotation should only take place when all three officials are in the
frontcourt
• A rotation begins when L moves laterally and penetrates the key
area
Center Initiates Rotation: Trap on Center Side by Mid-court
