How are her results in games? As a coach the last thing I would want to do is mess with something that was working, regardless of how unorthodox it looks....a player can stand on her head in the batters box for all I care as long as she knocks the cover off the ball!
Unfortunately she hasn't been hitting too good. Not bad but well below what she normally hits and her confidence is pretty low right now partly because of coach and partly for other things. She's been feeling a lot of pressure lately for the attention she got for committing and the new expectations. I posted a while back about her having some performance anxiety that has cropped up. Then having a coach that doesn't relate well to her or teenage girls and players in general and who doesn't talk except to point out mistakes just makes it worse.
This is not the first time that a coach has questioned her swing. It's just the first time that she hasn't quieted them down with her results.
I also want to say that the hitting advice is just part of the reason for the post. The main reason was his comment yesterday that coaches can take away scholarships. What person who doesn't know her has the nerve to say something like that at a time when she's already feeling insecure? That is borderline abusive given her mental state right now.
