“This is an example of a defensive foul for blocking. The defender, Ryan Arcidiacono, who is positioned in the Lower Defensive Box, does not allow the offensive player, Steven Adams, the room to land after receiving the ball. Defensive players positioned inside the Lower Defensive Box must allow airborne offensive players who are catching the ball, the opportunity to land without contact. Please note that the Lower Defensive Box is the area from the bottom tip of free throw circle to the 3′ posted up marks.”
