Need clarification on moving/illegal screen

[BillyMac]

A moving screen is not in and of itself a foul, contact must occur for a foul to be called. If a blind screen is set on a stationary defender, the defender must be given one normal step to change direction and attempt to avoid contact. If a screen is set on a moving defender, the defender gets a minimum of one step and a maximum of two steps, depending on the speed and distance of the defender.
