Make High School sports fair! All players deserve guarateed play time!

Our 9th grade team has a large team and are being told that unless there are two games, there will not be guaranteed play time. This means, if there is only one game, the A squad from last year will get to play all the games, whereas the B squad from last year will be "benchwarmers". These kids need a positive experience and this is not it. My son called himself the C squad of the C squad. How can these students work hard to prove themselves if this is how they feel?
