I'm thinking of doing this: http://theloveofthegame.com/video-shot-analysis/ - what do you guys think?

I've met him before and he's worked with people like Steve Nash, Ben Gordon, Channing Frye among others. He's with the Magic working with Aaron Gordon right now.

If money is not a big issue, I'd recommend finding a personal coach whose expertise and style match you and what you're trying to improve. The odds of this $99 turning into a lasting improvement are not high. That being said, it's only $99 you're risking.
