Moving Screen

Question
I always thought if the person setting the pick moved, it was a moving screen.  If the person can stay between the defender and the ball-handler in a "straight line" from the top of the key to the bottom of the lane, how do you defend the play.  You will really have uncontested lay-ups, particularly at younger ages where teaching a "switch" is virtually impossible and where you must play man-to-man.  What if the defender has to move into the "screener?"

Answer
HI Dan,

Anyone setting a screen MAY NOT move. But keep in mind, a player setting a screen must make contact with a player on the opposing side in order to draw the foul. There really is no such thing as a moving screen.  The call is an illegal pick, or illegal screen, and again, there must be contact, or if the player setting the screen moves and impedes the defender from continuing his/her move to defend the ball, then it can be called again. In younger ages, if there is a "moving screen" sometimes it's best if the referee blows his/her whistle and gives a warning rather than actually calling a moving screen since there really is no such thing. In all the years I have been officiating, you don't see too much of it at the younger level, and if a player does screen and move, it's not done intentionally to gain an advantage.
