Good to be back!
I don't think that would do as good of a job. If you sit on your butt and shoot a shot, any shot, the ball has to go much more vertical, than horizontal to reach the rim. With Shaq being so tall, with such long arms. He can shoot the ball down and still make it no problem.
The exercise that I stated above is to develop rhythm... that is what Shaq lacks. His style is not going to change this late in his career, but any bad shot with rhythm can be consistent. See 'Leandro Barbosa's two hand jump shot'.
