Use the "fire" analogy: if the ball feels like it's coming close enough to "burn" you, it will "close" (come towards you); if it feels far and safe, it will "open" (go wide).
This is a great lesson for simplifying a common problem players face. The coach offers a very straightforward way to know if the ball is going to open or close off the back glass corners. It cuts through complicated advice and gives you a simple feeling to focus on during play. This can make a real difference in your backcourt comfort and consistency.
