This is an example of a defensive foul for blocking while in the Restricted Area. The Restricted Area is the area within the arched line on the court below the rim. It applies to secondary defenders and was established to ensure offensive players have room to drive to the basket without allowing defensive players an unfair advantage in drawing an offensive foul. To be considered legal and to draw an offensive foul, a secondary defensive player must have both feet established completely outside the Restricted Area line. On this play, the secondary defender’s right heel is on the Restricted Area arc.
