Biggest rules/mechanics changes of the last 5 years

Signals:

Signal Chart Added a mechanic of a defensive tip (brushing one hand over the other above the head) to indicate the official has ruled the ball entered the backcourt as a result of contact with a defensive player.

2-9-1: When a foul occurs, an official shall signal the timer to stop the clock. The official shall verbally inform the offender, then with finger(s) of two hands, indicate to the scorer the number of the offender and the number of free throws.

The final change approved by the Basketball Rules Committee is a change in the signal when a held ball occurs. Now, when a held ball occurs, the covering official(s) shall stop the clock using Signal #2 (straight arm, open palm extended) while simultaneously sounding the whistle. This change should help to alleviate conflicting calls by officials when a held ball occurs. Stop Clock for Jump/Held Ball-Part 3 of the NFHS Basketball Officials Manual-#3: When a held ball occurs, covering official(s) shall stop the clock using signal #2 (straight arm, open palm extended) while simultaneously sounding their whistle. Then both arms are extended straight out, at chest level, with fist clinched. Thumbs are displayed as a part of the signal. Signal is given with both arms moving in an upward motion. Should be followed with a directional signal (See #6) indicating team possession.

The official signals were also modified to use the same hand signal for a player control foul and a team control foul. Officials should use Signal 36, which is a hand placed at the back of the head, for both types of fouls. Previously, a team control foul was communicated with a punch of the hand.

Officials Signal Chart and Officials Manual: Establish a signal to be used after a basket is made and there is a stoppage in play. The signal is used by the officials to indicate the team inbounding the ball may run the baseline. The signal will be executed by extending the arm laterally, bending the elbow at a 90-degree angle, moving the hand and forearm from the elbow in a waving motion horizontally along the end line. A new picture will need to be added to the signal chart.
