No. The trajectory on his three-point shot has been too flat, or low, in recent weeks. In terms of geometry, the ball has a much better chance of going through the hoop when it is coming from a nearly vertical trajectory. Basketball shots are a little like golf, in that the ball rises, then falls at a steeper angle. But you have to get that rising arc to begin with, and Keegan often fails to do that.
The problem is certainly correctible, though why no one on the Kings staff--or for that matter, another player--has helped him with this, I have no idea.
