I love Lowe's articles.
Cousins doesn't so much participate in a pick-and-roll as he does execute a pick-and-stand-there. You can find a lot of pick-and-rolls where Cousins doesn't cut to the rim — doesn't move at all, really — until after the ball handler has picked up his dribble and gone into a shooting motion, suggesting Cousins only revs up when he senses a chance at an offensive board.
