High School Soccer…

So apparently the coach thinks some kid thats a junior is better then me, when the kid has never played travel or soccer until high school. I’ve been playing soccer since I was 4 and travel since i was 9. Im a sophomore now. Whenever he plays me I always work hard and produce positive plays. The other kid does work hard but doesnt know what to do with the ball when he gets it. We both play outside left back and im a lefty while the other kid is a righty. Does anyone have any idea why the coach would rather start him over me?
