“This is an example of a defensive foul for illegal contact, as the defender does not maintain legal verticality. The defender, Wendell Carter Jr., does not maintain a legal vertical position, as he jumps toward the shooter, Donte DiVincenzo, and in doing so, the defender initiates illegal contact. To be considered legal, the defensive player must establish legal guarding position prior to the start of the offensive player’s upward shooting motion, and he must also jump vertically in an attempt to defend the shot. The secondary defender here fails to meet that criteria, and this is a defensive foul.”
