The ball keys the rotation. As a guideline and
depending on playing action, the Lead should
close down and may move laterally to ball side
when the ball penetrates the free throw lane line
extended nearest the Center.When the Lead rotates
the Trail and Center Also rotate positions.

Rotation of Officials as Ball Moves From One Side
To Another

• EXCEPTIONS Quick shot or drive to the basket.
  When a player with the ball starts a drive to the
  basket from an officials PRIMARY AREA, that
  official has the player and the ball all the way
  to the basket. When the Trail rotates to Center,
  that official picks up new primary coverage off
  the ball. Lead must officiate players in the
  post, even while moving across the lane. In most
  situations, Lead moves to ball side.
• Note There should never be two Trails. There
  may be two Centers for brief periods of time.
