I've always been fanatical about studying jump shooting form, every time I watch a game I always dissect everything about a player's jump shot, release point, elbow location, follow through, etc.
This site is interesting to me because the author's chief argument that it is no longer necessary to have your elbow directly under the ball - which is something I have always been taught and always focused on when shooting. I'd consider it a cardinal sin to not have your eblow tucked in and under the ball (ahem, Lebron) so this pretty radical. At the same time I also noticed that great shooters like Ray Allen do not have their elbow directly under the ball, as seen in the diagrams on this site.
Now I played DII in college and shot over 40% from three for my career so I know a thing or two about shooting. But I'm always looking improve, since my career ended and I don't have time to shoot 500-700 jumpers a day my shot has obviously gotten worse. It doesn't feel as natural, effortless and fluid as it once did. I'm going to try to restructure it based on this book with my elbow not directly under the ball.
Just thought I'd share the site and see what other people's thoughts were.
