that's not great, especially if it is not a new thing. I'm sure Tennis Smart will not be sending anyone else!
if coach had changed that may have been a different story, but doesn't appear to be the case. It can be a lottery if coach changes as they want to change things and the kids can be collateral damage. That the college allows coach to do such things on a regular basis is damming of that coaches inability to actually coach/develop players and of the Athletic Director to allow such a thing to happen to the young people under their stewardshi.
