Pick and Roll Rule

[Jurassic Referee]

POE 4A from the 2007-08 NFHS Rule Book:

SCREENING: A legal screener must be stationary prior to contact within his/her vertical plane(hands, arms, legs and feet no more than shoulder width apart). When these two requirements are not met, and when there is sufficient contact delivered by the screener to bump, slow or dispace, it is a foul on the screener. When a screen is blind, outside the visual field or a rear screen, it is only legal when the screened player is permitted a normal step backward. The screened player must then make a legitimate attempt to get around a legal screen without forcing rough or "displacing" contact. This type of contact must result in a foul on the screened player. When a screener is illegally moving in an attempt to set a screen, but no contact occurs with the opponent, no foul has been committed.

Note that contrary to Judtech's opinion, the red-highlighted sentences above apply to a pick-and-roll play.
