When the ball goes below the

primary on-ball coverage.
T focuses on the area off-ball
and should extend coverage to
assist with the open area on
the opposite side.
In transition to the other end
of the court, L must remember
to go back to the other side of

LEAD BALL-SIDE COVERAGE
If the majority of players or

quickly move back across the
key to cover the play.
If there is a quick shot or drive
to the basket, L should just
close down to the near free
throw lane line extended and
work the play.
T should close down when L
moves across the lane

L & T are in proper
position for a
normal frontcourt
offense.
When a team goes
into a “four-corner”
or “delay” offense,
the officials must
change their basic
positions and move
to the areas
indicated.
If the corner player on
that side drives to the
basket, L can cut
across the corner to
observe the action
near the basket.
Officials should react
quickly and properly
when a team shows
this kind of offense.15
