Awe, you are the one that posted that pitching video.Thank you. She's my pitching student.
I recall commenting that it looked like she was avoiding brushing, and you followed up stating that she had been working on brushing. Thought it was a good example of someone that was instructed to brush, yet continued to avoid brushing.
That's sort of why I like Mike White's no-bones-about-it approach ... elbow-to-hip was his instruction.
