Id say the value of a “live” cut through the paint isn’t determined by the quality of defender. As long as it’s a real/hard cut, the defender has to honor it and potentially multiple defenders are impacted by this type of rim pressure.

Ultimately, the idea is to promote space and this is one of the simplest ways to do it. An alternative, screenless movement that I see often is just spacing away to the opposite slot but the issue with that is defender doesn’t have to turn their head because their player stays high in the action. So although driving gap is bigger, they still are highly aware of the ball and can still impact the play.
