We all know of teams where the coach builds a team but in order to win tournaments and build their reputation, invite guest players to star for the weekend. As they win these tournaments, they then hold tryouts based up team/coach success. You have to ask yourself what is the point where your child will be phased out. These teams typically by 14U are very good and draw college coaches at exposure tournaments based upon success. These coaches typically carry spare uniforms in the car and so, you never know what team is going to be there and what your child's role will be in any given exposure tournament. If you are good with that and confident that this coach can't replace your dd then stay. If not, run. As a side not, one of dd's friends played on one of these teams. She was good, they paid their $1.400 to play weekend tournaments and exposures and they wore their "colors" everywhere showing everyone what team their dd had made. Great except when the exposures started, she might have seen one or two innings at her normal position. Still, they put on their recuritment brochure the team name and did the YouTube promo in the team uniform. Still, no interest since she was never playing her normal position except in local tournaments where superstars were not recruited.
I have an acquaintence with a similar situation. Hauled his kid out to the Sparkler last week and his kid managed to pitch 2 innings. Not much of an exposure tournament for her. The irony is many of the local schools in her area come out to see her play all of the time, but they wanted to be on one of these teams and drive a couple hours one way to practice a couple of times a week for limited playing time.
