Coaches coach. Players play. Officials officiate. Parents can cheer if they want, but they don't do any of the first three things. So since playing time is a coach's decision, and he'll always play who he thinks will help them win, there's no explanation that would make any unhappy person happy. It's a pointless question that no coach should bother answering to include coming from a player. "What can I do to get more playing time?" Which almost never means "help me become better" but instead means "Since they can't ask you, my parents put me up to asking why you stupidly allocate playing time?" Be positive, work hard, get better, and more playing time follows. End of story.
