Blocking, Secondary defender does not allow airborne offensive player room to land

This is an example of a defensive foul for blocking. Defenders positioned inside the Lower Defensive Box must allow airborne offensive players catching the ball the opportunity to land without contact. The Lower Defensive Box is the area from the bottom tip of free throw circle to the 3′ posted up marks. The defender on this play does not allow the offensive player the room to land after receiving the ball, and this is a blocking foul.
