The opportunity to make an alternating-possession throw-in is lost if the throw-in team commits a throw-in violation. If either team fouls during an alternating-possession throw-in, it does not cause the throw-in team to lose the possession arrow. If the defensive team commits a violation during the throw-in, or the throw-in team commits a violation other than a throw-in violation, the possession arrow is not switched.
Rationale: By limiting the loss of the possession arrow to a throw-in violation committed by the throw-in team, there is consistency of penalty and ensuring the loss of the arrow is associated with the violation of a throw-in provision not another non-related violation. The loss of the arrow associated with a violation should be limited to those violations in rule 9-2-1 thru 9.

Exemption: A pass or any other loose ball in the front court that is deflected by a defensive player, which causes the ball to go into the backcourt, may be recovered by either team EVEN IF the offense was last to touch the ball, without player control, before it went into the backcourt.
Rationale: The exemption to this rule would alleviate the official's duty to determine if a ball was simultaneously touched, by the defense and then offense (in a backcourt violation situation), and helps them to continue to officiate the defense.
The definition added would clear up confusion as to what a "loose ball" is and what it is not.
Other Rules Affected:
Loose ball: When a player is holding, dribbling, or passing a ball, a loose ball occurs if the player a) fumbles the ball, b) has an interrupted dribble, c) loses player control when a defender bats or deflects the ball from their possession, d) has a pass deflected, or e) releases the ball during a try.

A player shall not be the first to touch the ball after it has been in team control in the frontcourt, if he/she or a teammate last touched or was touched by the ball in the frontcourt before it went to the backcourt. A pass in the frontcourt that is deflected by a defensive player so that the ball goes into the Backcourt may be recovered by either team.
Rationale: To correct a likely prior omission and ensure that a team is not unfairly disadvantaged. This also makes the play situation on the deflected pass consistent with other codes with very similar team control and backcourt rules.

Allow dunking during the pre-game warmup period.
Rationale: Is pre-game considered a "dead ball" period? My rationale addresses a few areas.
1. An attempt to get more people attending high school basketball. Attendance is down across the country and this rule change may get more people interested in attending a game, if for no other reason than to watch the kids attempt to dunk in pre-game.
2. It may be the only athletic act that is allowed during a game, but during pre-game warmups.
3. There could be, and I emphasize could be, a potential liability suit if a player is injured while attempting a dunk during a game, yet was not allowed to practice/warmup the act of dunking during warmups.
4. There is less risk of injury dunking in warmups, then during a game while being contended by an opponent.

The head coach shall not permit a team member to participate while wearing an illegal uniform or illegal apparel.
Penalty – Direct technical foul charged to the head coach. Rule 10, Section 6, Article 4: The head coach shall not permit a team member to participate while wearing an illegal uniform (see 3-4) or illegal apparel.
Rationale: It makes the rule easier to understand by officials, coaches & players. We are spending more time discussing what is legal & illegal with uniforms & apparel than we are spending with hand checking, post-play, etc.
It will also put more responsibility on coaches to make sure their players are dressed legally.
