Not playing regularly on your club team can dramatically impact the scholarship process. In order for college coaches to know if you deserve a scholarship, they would like to see you play in person. It should go without saying that if a coach comes out to watch you sit on the bench, then that scholarship becomes even more elusive.
Before making a decision to leave a club, I always suggest getting an honest analysis from someone who knows the game. So, please talk to your coach. Ask him/her what you need to work on and what you can do to get on the field and help the team. Don’t start a gossip ring. Don’t compare your situation to anyone else's. Just have an honest conversation with your coach and see where you stand.
There are times when the situation is truly not fair and I have seen it. Politics can creep into youth sports, but in my experience it has not to the point where you wont get an opportunity. On competitive club teams, the best players typically play. Make sure you are being realistic with the situation. Do you attend practice, show up on time, and work hard? Make sure you are accountable for your actions. However, if it's still unfair, then the best thing to do is find a club where you will get an opportunity as long as you remain on a high level club team.
At the end of the day, you are responsible for earning your own scholarship. Not a coach, not your teammates, it's you! Make a decision on a club where you will develop as a player and get a fair opportunity.
