Are they saying legal or have they not yet said anything implying it is legal?
So why not just fix it?
In my opinion I have to believe she has tried but it is not there yet. I am sure it is a little embarrassing to wear that. I also have to believe coach understood all the negatives that would follow but had to do it because they could not fix it. Oh I bet they tried. The real problem? All the young pitchers are allowed to pitch illegal because of this or that or what ever reason. Coaches don't fix it because it is not needed (and a good portion probably don't know how). If you bring it up, everyone gets all defensive at the tournaments and the coach who points it out becomes the bad guy/gal.
NCAA rules say equipment used in competition must be available to the general public.
