I’ll use this page to post information regarding the NBA rules that the referees are selectively enforcing.
Official rules of the NBA: There are also summaries of rule changes from season to season, rules history and the most misunderstood rules. That last one might be one the officials should review on a regular basis.
NBA video rule book: Pretty cool resource for explanations of different types of fouls.
Illustrated Hand Signals: Good resource to understand what the various hand signals that officials use. It doesn’t, however, give illustrations of hand signals fans use to show their distaste with the referees.
