Just for information and/or clarification - this Homer Kelley swing was in the process of showing that you needed to HIT DOWN on the ball. I wouldn't consider it full power. I wouldn't say that it was a "normal" swing for him in this regard- there was very little concentration and no target awareness- he is emphasizing the downward blow- and thrust down plane- essentially demonstrating that to a student. So my comments are really just a minor addition - broadening the context of the clip a little- for anyone that is interested.
