and will go up if good w/ C mirroring made basket
![Page 17: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/17.jpg)
Lead Official Closes Down, Prepare for Rotation
ROTATION SEQUENCES
![Page 18: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/18.jpg)
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
![Page 19: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/19.jpg)
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
![Page 20: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/20.jpg)
Lead Initiates Rotation, Trail goes to New C, and C goes to New T
![Page 21: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/21.jpg)
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
![Page 22: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/22.jpg)
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
![Page 23: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/23.jpg)
BETTER TO HAVE 2 C’S THAN 2 TRAILS
WHEN ROTATING!
![Page 24: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/24.jpg)
DO NOT WAIVER! IF YOU’RE GONNA ROTATE..GO!!
![Page 25: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/25.jpg)
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
![Page 26: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/26.jpg)
Fixing a Unnecessary Rotation, Quick Turnover, Lead Banana Back
![Page 27: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/27.jpg)
Trail Positioning
• Work the angles and see space– Move to improve
• Don’t get stuck too far in court– In way for transitions
![Page 28: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/28.jpg)
When the “C” can initiate 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 (Goes to a Trail position)• 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)
![Page 29: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/29.jpg)
Center Initiates Rotation: Trap on Center Side by Mid-court
![Page 30: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/30.jpg)
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
![Page 31: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/31.jpg)
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
![Page 32: Basketball Officials Clinic 3 person mechanics. 3 Person Terminology Rotation Switch L Official (Lead) C Official (Center) T Official (Trail) Close Down](https://reader038.vdocuments.site/reader038/viewer/2022103015/5519a836550346c4608b479b/html5/thumbnails/32.jpg)
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 & Stay Table side
• Hustle around players & Stop in reporting area (Federation mechanics)
– Table side official go to calling official’s previous area for throw-in or prepare FT
• Do not cross vision line of reporting official
