Here is the lesson to be learned that seems to be lost nowadays.
If your child is not getting playing time it quite possibly may be political. You have an opportunity to teach your child to keep quiet and work even harder and possibly for a long time. If the skill level improves and she becomes better than another "politically connected" kid then she should see increased playing time and opportunities. I would think any coach would want to improve their team and misusing resources based on political opinions is foolish and very noticeable. BTW...if she does work hard and improve and the coach STILL does not use her properly then she gained several things. 1-improved skills and confidence in her ability, 2-the ability to excel in club ball or skills camps and finally, 3-the knowledge that she didn't let an immature coach or difficult situation prevent her from improving...ALL GREAT ATTRIBUTES TO HAVE FOR THE REAL WORLD. Keep in mind the alternative approach of complaining, arguing and bad mouthing is heard and emulated by your kids...all of which gets you no where. Just a thought...
