PIck and Roll - Illegal Screen

[ballgame99]

The judgement that needs to be made here is whether the "roller" is really rolling to try to receive a pass or go rebound, or if he/she is just rolling enough to hold up the defender. You can usually tell the diference.

Why the "roller" is rolling is irrelevant. It is the effect of the action that matters. If the defender attempts to go under and the roller moves such that it cuts them off and prevents them from getting to the player they were trying to guard, it is an illegal screen (assuming contact). Of course, if the shot or pass is already in motion, that might change things as the play to be defended will have changed.
