4 CAPTAIN S MEETING & JUMP BALL PRODURES

5 Pre-game Positions

6 Jump Ball Positioning 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 U-1 R U-2

7 Ball Goes Right

8 Primary Areas of Coverage 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.

9 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)

10 Lines of Responsibility: T-Green, C-Yellow, L-Blue

11 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

12 End Line Throw-Ins in the Frontcourt L may administer throw-ins on either side of player when staying in frontcourt

13 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

14 Shot & Rebound Coverage

15 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

16 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

17 ROTATION SEQUENCES Lead Official Closes Down, Prepare for Rotation

18 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

19 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

20 Lead Initiates Rotation, Trail goes to New C, and C goes to New T

21 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

22 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

23 BETTER TO HAVE 2 C S THAN 2 TRAILS WHEN ROTATING!

24 DO NOT WAIVER! IF YOU RE GONNA ROTATE..GO!!

25 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

26 Fixing a Unnecessary Rotation, Quick Turnover, Lead Banana Back

27 Trail Positioning Work the angles and see space Move to improve Don t get stuck too far in court In way for transitions

28 When Lead helps C & Rotate Team just established frontcourt possession on C Side Player is feeling pressure or is being trapped C should turn head and/or open up to the play and officiate Lead must recognize situation and rotate over Trail must recognize and help at 1 st then move down to C Lead should use vision to anticipate this situation when ball crosses midcourt & sees pressure or ball settling

29 Rotating when C has play on his side
