Your daughter needs to understand that not making a team doesn't mean the coaches have judged that she's not good enough for the team, or that all their current players are better than her. It just means that she is not the best candidate for the few openings they have. In other words, she might be (and probably is) better than some girls already on the team, but she's not (in their opinion) the best player they think that they will find to fill a particular role. I know girls better than my daughter who wouldn't make our team at the moment because we can need a pitcher or a catcher, and nothing else will do.
