The lead official is responsible for on-the-ball coverage when the ball is located in the
shaded areas (Diagram 55). The dark shaded area indicates the area of shared
responsibility with the trail official.
The primary duties for the lead official include:
1. Pivot/post play.
2. Play under the basket.
3. Fouls away from trail official.
4. Drive to the basket on lead’s side of the playing court.
Remember the principles of mechanics:
1. Always move when the ball moves.
2. Box-in all the players between the officials’ field of vision.
3. Look for the spaces between the players.
4. Step back from the endline to get a wider angle of vision.
