So... I wrote this next part without any sound, so sorry if it echoes what you said... It might be a little nit-picky, but I could see getting that wrist loaded earlier would help with the ball positioning. It seems like the ball goes between the legs, then comes out to the right once the wrist gets loaded, but it loads super late in the shot. It would simplify the shot and make it more repeatable. Without seeing the front view it seems as though the shot path might be crooked, so it would straighten out the line. I agree with @Kevin Berry on the footprint piece as well. Since that is what you said and not really an add on, I would add on the idea of dropping the hips and sitting into the shot. Kinda the karate chop to the back of the knees idea. It goes along with simplification and repeatability, plus adds some more power to the shot.
