Mechanics Changesfor 2013-15
• A change has been made that removes the requirement for when the lead official calls a foul and the ball is going from backcourt
to frontcourt with no free throws, to return to the endline and administer the throw-in
• A tipped-ball signal has been added to the official signals to indicate when the ball was touched by the defense before going into the
backcourt.
Mechanics Major Editorial Change
• Player and team control are in effect during a
throw-in.
Mechanics Points of Emphasis
• Dead ball officiating.
• Proper mechanics and signals.
Review of MechanicsChanges 2011-13
TRAIL MIRRORS CHOP SIGNAL(2.2.2.C.6 New)
• In Crew of Two Only: The Trail will mirror the Lead’s stop- and start-clock (chop) signal to ensure proper court coverage.
• It is often difficult for the timer to see the Lead start the clock on end line throw-ins.
• The change will promote accuracy in starting the clock and is the same mechanic used for a crew of three.
START-CLOCK SIGNAL(2.4.4.B.4 ; 3.4.4.B.4)
• A visible signal (point to the table) was added to indicate when the timer should start the clock on a time-out.
• The addition of this signal will help promote consistent administration of time-out situations.
Major Editorial Changes
2.4.5.A & 3.4.5.A: Clarified that the
officials shall return to the court
when there is 3 minutes remaining
in the halftime intermission.
2.4.7.B & 3.4.7.B: Text changed to
the current concussion guidelines.
