This is a very interesting discussion to me. If you think about a lot of the great pitchers over the years most were originally taught HE. Their bodies developed the IR naturally and they rise to the top. How do we know most were taught HE because that is what they teach. With my DD she was taught by a former SEC standout and started learning what I found out on here was HE. Now watching videos you could tell that is not how she pitched in college. Over time my daughter started developing more IR movement naturally. And had many of the important parts of IR that she was never taught or even had a clue they were happening. So it does make me wonder if trying to teach movements instead of the body figuring it out is better/worse. Once they figure it out naturally is it better to exaggerate /make tweaks or let the body teach itself? Not every girl will be a great pitcher. No matter the instruction or amount of time put in. So are some pitchers that are natural getting held back by changing and teaching mechanics that give everyone a better chance to make it? Or would the top pitchers be better off learning the same way most of the former greats learned?
