Well of course you had to pick videos of Arod from Seattle and Texas. He also throws side-arm. Good thing he had Olerud at first to make him look good.
With that said, I don't disagree with your premise.
Dr. Yeager, I've asked you on multiple forums now about the swings you used in your research. They do not represent the player's game swing nor what elite hitters do. Why should I buy into your research when you aren't showing a high level movement pattern? I think this is a very fair question. You've done multiple videos and sell products based on your research. I respect what you do. My question is 100% content based.
