The reason the wings are stagnant when Lowry is on the floor is because they don't bother to makes cuts because they don't think Lowry will see them. Amir and now Ed understand perfectly that if they make cuts or roll to the basket Jose will get them the ball. That is the way basketball should be played. This does not happen for them when Lowry is at the point. Why make the cut if your PG is not going to deliver the ball?
Because even if you don't get the ball you'll get somebody else an easier shot. That's why.
