RB - please describe in a bit more detail what you see in Bahl's current mechanics (not pitches from a few years ago) that are so poor you call them a "hot mess" and a "determent to success"? If she was leaping everytime with the intent to replant then I could see that messing with her hips, knees and timing which would probably (even with her athleticism) detract from her speed, spot and spin but that doesn't seem to be the case.Leaping is just symptom of poor lower body mechanics. If you look at most any skippy, you will see that their mechanics are a hot mess. Barnhill was the poster child for someone who was able to overcome poor mechanics with raw athleticism. You can see this at most any high school or TB game. You will regularly see kids with a god awful swing mechanics who regularly hammer the ball. Most wash out as the level of play increases and out paces their athleticism. Some like Barnhill and others have the athleticism and go on to play at a very high level. But they are the unicorns. I cannot imagine anyone with a basic knowledge of pitching mechanics that would want their kid to take lessons from Barnhill, Bahl, or others. Would be interesting to see what some of them could do had they had proper instruction and developed truly great mechanics.
