Honesty is always the best policy, and I would encourage players/families looking for teams to absolutely talk with the coaches and ask them questions about needs, philosophies, etc., and to get a feel for the coach's sincerity. When my DD was playing, I wanted to know who she was playing for, what position(s) she would likely be playing, and get a feel for if the coach really knew what they were doing. Several posts on another thread suggest a parent should "go hide in the car" at tryouts ... I would call that irresponsible parenting. Its important that everyone is on the same page if you want to avoid problems later.
As mentioned above, I posted in the tryouts section what was going on with my team (i.e., about 1/2 the girls were moving up), and what the purpose of the team was (i.e., girls who want to play in college and whose families are willing to make the commitment that requires). I probably should have also added that all returning girls have to try out again the following year, so there is no guarantee that all of these girls will try out or that they will make the team (one of the reasons they try out again is so that the new girls can see the talent level and attitudes of those who are coming back). While they do have to re-tryout, they are all pretty talented and I think they are having a good time this year, so I am hoping and trusting that they will be back!
Here's hoping that everyone who tries out for teams this coming year finds the situation that is right for them. Parents doing their homework will help ensure this happens.
