This is an example of an illegal off ball screen. In this example Black 22 sets a screen within the field of vision of Purple 4. As this screen is set within Purple 4’s field of vision the screener does not have to give time and distance for the defender to avoid the screen but he must be stationary at the point of contact. Black 22 is never stationary at the point of contact. This is an illegal screen committed by Black 22.
