What is the difference between Crew Chief, Referee, and Umpire positions in NBA officiating?

The Crew Chief is the leader of the crew with proficiency in all positions, responsible for high-level play calling, crew management on and off the floor, and handling any game situation. The Referee serves as the glue for the crew through consistency and teamwork, proficient in all Umpire requirements and capable of handling plays in secondary coverage areas. The Umpire aggressively and accurately calls plays in their primary area of responsibility, handling basic mechanics including rotations, positioning, and clock awareness with strong rules knowledge.
