All the physical flaws that people have pointed out in her motion do exist, weak FSR, glove swim, locked arm/elbow (no IR), not opening enough. Trying to address each of them leads to a game of 'whack a mole'. When you fix one, then move on to another, the first one comes back. And if you're not careful the pitcher can get overloaded with things to remember to do. I try to look at these things as symptoms not causes. The real skill in coaching is not so much in diagnosing flaws, it's in coming up with the cues/drills that lead to real change. The motion that she uses is her motor skill solution to the task of throwing/pitching a softball underhand. If you took 10 dads and asked them to pitch BP all 10 would use the same action (from 9 o'clock to 3) that she uses, bowling, pushing, shoveling, HE, etc. She just adds a real fast arm circle. The key is to lead her to another way of throwing underhand by changing the task, ie, skipping stones. I have used 3" wooden model train wheels instead of stones. I have used J-bands for resistance from 9-3 o'clock and had them bowl then use IR so that they could feel the difference between the two arm actions. I have tried having them throw mini footballs, dog toys, and the Nerf Vortex underhanded. I built a brace of moldable cast material to hold the elbow at 90 degrees. What typically happens is that they can IR when using these training aids but the transfer to the full motion is weak, especially if they have been pitching HE (bowling) for a while. I have had the most success with the small ball circle drill. They start with a bent arm, almost 90 degrees, put their attention on the ball and it's movement through the circle, keeping it small, tight. If they do it right they will come down the back side with the elbow leading and naturally IR-whip the ball.
