  3. 3. 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 Center) • Trail has his/her sideline, midcourt line, and backcourt line (when appropriate) • Center has own sideline (may help with midcourt if rotating or transition)
  4. 4. Lines of Responsibility: T-Green, C-Yellow, L-Blue
  5. 5. Throw-In Responsibilities • Always put the player between you and the basket • “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—essentially the “C” becomes the new “T”
  6. 6. 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
  7. 7. 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 only signals on fast break or in SS corner, never good
  8. 8. When to initiate rotation at Lead YOU HAVE TO USE YOUR PERIPHERAL VISION AT ALL TIMES!!!!! • Aim to have two people strong-side (ball-side) if possible • 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 • 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
  9. 9. 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
  10. 10. 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
  11. 11. BETTER TO HAVE 2 C’S THAN 2 TRAILS WHEN ROTATING!
  12. 12. Trail Positioning • Work the angles and see space – Move to improve • Don’t get stuck too far in court – In way for transitions

  14. 14. 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
  15. 15. Foul Reporting Mechanics • Switch with the least amount of transition • Calling official freeze after call & notify players/partners situation • Clean up before reporting – Report Foul & Stay Table side • Hustle around players & Stop in reporting area – Table side official go to calling official’s previous area for throw-in or prepare FT • Do not cross vision line of reporting official
  16. 16. Free Throw Mechanics: Non-rebounding free throw Trail bring in subs
  17. 17. 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
  18. 18. 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)
  19. 19. Questions? • Next up mechanics and calls
  20. 20. Calling a Violation • Blow Whistle – Give a sharp blast – Weak whistles = indecision • Raise arm – Open hand – Straight in the air • Give proper mechanic for the violation which occurred

The ball can be thrown anywhere. THE POINTS: Right Foot, Left Foot, and Ball
  25. 25. “Palming the Ball”/Carry • Player rolls his wrist over the ball in an attempt to gain an advantage – Most players carry with their normal dribble. – Distinguish between a person’s normal dribble and an attempt to gain an advantage. – A “Carry” is a specific form of traveling.

Every player is entitled to a spot on the floor provided such player gets there first without illegally contacting an opponent. A player who extends an arm, shoulder, hip, or leg into the path of an opponent is NOT considered to have a legal position if contact occurs. • Obtaining a legal guarding position: – The guard must have both feet touching the floor – The front of the guard’s torso must be facing the opponent.
  32. 32. Closely Guarded • Closely guarded is when a defensive player is “actively” guarding a player and is within six feet. – 6 feet is the Distance – 5 seconds is the Count • Closely guarded only applies to when the ball is in the FRONTCOURT. • The 5 count resets every time there is a change in the ball handler’s “status”: – A player can hold the ball for 4 ½ seconds. – Then dribble for 4 ½ seconds. – Then hold the ball for 4 ½ seconds before they have to get rid of the ball.
  33. 33. Not Closely Guarded • THE COUNT ENDS… – if the defense is not within 6 ft. – anytime an offensive player gets their head and shoulders past the defense – anytime the defense is not between the player with the ball and the basket The defensive player may switch with another defender:  the count will continue as long as the 6 ft barrier is not broken

  42. 42. Holding • HOLDING: Illegal contact that impedes the lateral or vertical movement of an opposing player. “Gold, #2, holding. Red ball on the side.”
  43. 43. Double Fouls • DOUBLE FOUL: simultaneous personal fouls by a member of each team. • Play from POI. – If no clear possession at POI (i.e. loose ball, shot), results in alternating possession. This is a great call to clean up overly aggressive post play.
  44. 44. Block • BLOCK: Illegal personal contact which impedes the progress of an opponent. • ISSUES w/ CALLING BLOCKS – “Referee the Defense” – Principle of Verticality – Blarges!
  45. 45.
