  • Basketball signals mech-2014

    1. 1. 2014 Basketball Officials Clinic 3 person mechanics
    2. 2. 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
    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
    13. 13. 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
    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
    21. 21. Directional Signal • When the ball goes out-of-bounds: 1. Sharply blow your whistle 2. Raise your arm with an open palm 3. Signal direction for new possession
    22. 22. Violations • Floor Violations: Traveling, Illegal Dribble, Basket Interference, Carry • Free Throw Violations: Offensive and defensive (learn about in STATIONS) • Throw-In Violations??
    23. 23. 10 Second Back Court Violation A team must advance the ball beyond the center court line in 10 seconds. The Official will administer a visible 10 second count.
    24. 24. “Over-and-Back” Violation • An offensive player with the ball may not cross back over the half-court line once they have advanced the ball beyond midcourt. – A player that jumps from the frontcourt without the ball, catches the ball in the air, and lands in backcourt is legal because they never established possession in the frontcourt. –It is NEVER a violation on a throw-in. 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.
    26. 26. Traveling • Player is not allowed to travel/walk with the ball – Pivot Foot: Player commits to a pivot foot by landing on that foot first • If player makes a good jump stop, they can establish either foot as their pivot foot. • Player may pick up their pivot foot, but must get rid of the ball before returning it to the ground. – Player cannot jump with the ball and return to the ground without releasing the ball. • Jump Stop??
    27. 27. Illegal Dribble/Double Dribble Players cannot start a dribble after their first dribble has ended, or put two hands on the ball while dribbling. – Not an Illegal Dribble: • Ball has been batted/contacted by opponent • Loose Balls • After a shot attempt
    28. 28. Kick Violation • It is a violation to INTENTIONALY kick the ball with any part of the leg or foot. • Results in loss of possession for the violating team.
    29. 29. Lane Violation (3 count) An offensive player may not have any part of their body in the lane, while the ball is in the front court, for more than three seconds. Count resets when?? • Use preventive officiating before calling: – “Get out of the key Red!” – If a player is on their way out don’t call it – If player doesn’t move after the warning, call the violation
    30. 30. 5 Second Violation • Five second violations occur for: – Throw-ins – Closely-guarded 1. Blow your whistle. 2. Signal the stop clock violation. 3. Give 5-second violation mechanic.
    31. 31. Legal Guarding • GUARDING: it is the act of legally placing a body in the path of an offensive opponent. 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
    34. 34. Jump Ball  Jump Ball – when opponents each have their hands on the ball and neither can establish possession Held Ball Held Ball – when the defense prevents an airborne shooter from releasing the ball during a block RESULT  Alternating Possession
    35. 35. Goaltending  FOUR REQUIRED ELEMENTS 1. 2. 3. A shot or tap Downward flight Ball above the level of the basket 4. The shot has a chance to go in AWARD THE POINTS AFTER A GOALTENDING CALL AGAINST THE DEFENSE 
    36. 36. Basket Interference • Occurs when a player… – touches the ball, basket, or net when the ball is ON or within the basket – touches the ball while it is on the cylinder – touches the ball outside the cylinder while reaching through the basket from below. If committed by the Defense  Award the points If committed by the Offense  disallow the points and grant possession to the defensive team
    37. 37. “No Basket! No Basket!” • A basket, scored after a violation, must be waived off. • This call must be “sold”… – – – – Be LOUD Use emphatic signals Show no indecision Don’t hesitate
    38. 38. Time Outs • Three Timeouts • Each T.O. is for 1 Minute in Duration • These do not carry into Overtime Periods TIMEOUTS CAN BE GRANTED WHEN… 1. A team is in possession of the ball (player with the ball, or bench personnel) 2. Any DEAD BALL situation (either team may request one)
    39. 39. Hits: The Standard Hack • HIT : Illegal contact with the ball handler. “White, #42, hit. Black on the side.”
    40. 40. Hand Checks • HAND CHECKING: illegal personal contact by a defensive player, which impedes the forward or lateral movement of the ball holder. • Call the foul if the defender… – Impedes or restricts the movement – Dislodges or jabs an opponent – continually leaves a hand on an opponent
    41. 41. Push • PUSH: illegal contact by extending of arms which influences the movement of an opponent. “Red, #31, push. Two shots.”
    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. Principle of Verticality • Applies to being in a legal guarding position. • Player must remain in their “vertical plane”. – Arms must be STRAIGHT UP. – Player can jump vertically, but not out of the vertical plane. • Player must avoid contact with their lower body outside of their vertical plane. • Offensive player may not “intrude” a defensive player’s vertical plane in an attempt to clear them out. • A player that sticks out an arm, shoulder, hip or leg, into the path of an opponent is NOT considered to be in legal guarding position – and is responsible for that contact.
    46. 46. Player Control Foul • PLAYER CONTROL: offensive player makes illegal contact with a defensive player in a previously established legal guarding position. • A player moving with the ball is required to stop or change direction to avoid contact with a defender in a legal position. PLAYER CONTROL FOULS = Loss of possession / no free throws
    47. 47. Intentional Foul • Foul committed with no attempt to play the ball when the person being fouled has a “clear” attempt at a scoring opportunity. – Make sure they are not making any play on the ball. – If severe enough it becomes a flagrant foul • Result: 2 free throws (clear the lane) and the ball for the team that is fouled.
    48. 48. Technical Fouls • Never allow a player to disrespect you, the game, or a fellow IM staff member. • Technical Fouls are called when a player or team has violated the spirit of the game, disrespected the game, and/or disrespected a player.
    49. 49. Situations for a T • Any form of harassment towards a player or staff member (possible ejection) • Baiting, taunting, showboating, or spitting • Fighting, pushing, shoving (automatic ejection) • “Acts of Deception” – Waving a hand in an opponent’s face – Distractions during a free throw
    50. 50. More Technical Fouls • Delay of game • Crossing the out-of-bounds plane and touching the ball • Any flagrant foul (automatic ejection) • Slapping the backboard to redirect a shot • Example : a player shoots on the right side of the hoop and a defensive player on the left side smacks the backboard to make the ball rattle out of the cylinder.
