Basic Position & Coverage Responsibilities

1. The officiating crew consists of a referee and two umpires. The referee is the game’s administrator and decides upon matters not specifically covered by the rules. The umpires assist the referee. No crew member has the authority to set aside or question decisions made by a partner within the limits of their respective outlined duties. 2. The three officiating positions are referred to as the Lead, Trail, and Center. 3. The result of the jump ball to start the game or overtime period, the location of throw-ins and free throw administration, determine the Lead, Trail, and Center positions. 4. The Lead ’ s PCA consists of the free throw lane to the basketline and the area bordered by the free throw line extended and the three point arc on the Lead’s side of the basketline (see page 91). 5. The Center’s PCA consists of the area bordered by the nearest sideline, the division line to the nearer free throw lane line extended, the nearer free throw lane line extended to the free throw line, the free throw line to the basketline and the basketline to the to the end line (see page 91). 6. The Trail’s PCA consists of the area bordered by the nearest sideline, the division line to the farther free throw lane line extended, the farther free throw lane extended to the free throw line, the free throw line to the free throw line extended to the nearer three point arc and the three point arc to the end line on their side of the basketline (see page 91). 7. The specific primary coverage areas (PCA) serve as a guide to assure that the players and the game are well supervised by the team of officials. Officials must master the concept of PCA. They must be aware when the ball enters their PCA and when to relinquish ball coverage when it enters their partners’ PCA. When the ball is within an official’s PCA, concentration is centered on the players and the ball in that area. Pivot foot recognition is crucial as well as attention to more aggressive defense. Therefore, the official has a more narrow “on the ball” field of vision. Conversely, the “off the ball” officials are often free to improve the overall crew’s coverage by expanding their field of vision because there are fewer players and less action in their PCA. (see page 91). 8. Basic Positioning: the Lead a. In transition, is ideally ahead of the ball and the play. Should keep the players and the court in their field of vision by looking over their inside shoulder as they move toward the end line to become the new Lead. b. If it is not possible to be ahead of the play, the Lead should attempt to get an open look by “trailing the play” on potential contact situations in transition. (See diagram on page 94.) c. The official should select an initial starting position based on ball/ player location. (See diagram on page 93).
