“This is an example of a defensive foul, even though the contact on the play is initiated by the offensive player moving into the defender’s outstretched arm. The defensive player, OJ Anunoby, has his right arm extended, and, as the offensive player, Julius Randle, starts his upward shooting motion, he creates contact with the defender’s extended arm. Since the contact occurred during the shooter’s upward shooting motion, this would be ruled a foul in the act of shooting. If contact is made when a defender is in this position, even if it is initiated by the offensive player, it is a defensive foul, as the defender is responsible for his extended arm. To avoid being assessed a defensive foul, the defender must pull his arm back to avoid contact, or position it vertically overhead.”
