OP established this is a school team. Not a competitive team. If it is non competitive rec/school team then yes the kid should get playing time regardless of their ability. That is why they have competitive teams in the first place. My husband plays on a men’s league. there are guys there that are really unfit and terrible. They don’t tell them they cant play…they are just there to have fun and get exercise.
If a kid is not good at sports, or just wants to try out a sport, or just wants to have fun…they need a place to play like a rec team or a grade school team. If a kid wants something more then they should be on a competitive team.
The schools in my area are the main source of competitive teams. You might be thinking of “intramural” sports that the kids can sometimes get involved in. However if it is a sport where there is a winner and loser and someone keeps score there will always be some sort of pecking order.
Unless there is some sort of abuse or bulling going on by the coach or the players I have found it is best to let the coach coach. He may not even be a good coach but we all have to learn how to deal with that.
When I was a freshman in High school I was cut from the tennis team. The kid who got the spot was someone I had never lost to, he was obviously not as good and he lost every match. But his parents were the “right kind” of people. Meaning parts of the school were named after his family.

I was devastated. The Coach was the school priest, he was rather rough when I talked to him about it. I had the choice to quit and not play or play JV. I chose JV after some guidance from my father. I won the tournament title. Then the next year we had a different coach. I made the team. Didn’t get the “spot” I wanted (the coaches son got that) but won anyway. I just kept at it. I was unfairly treated, coached poorly, looked over, rejected and it taught me some valuable lessons.
I learned so much from that experience and it was not because my dad stepped in or the coaches suddenly saw my perspective but rather because I chose to learn a certain kind of perseverance and way to deal with life. To me, that is the redeeming quality of sports.
the point of the story is not that I won a state title to prove everyone wrong. (I did) or even if you work hard you can accomplish anything. (you cant) But rather the point is that in life things are not fair, there are rejections and setbacks. It is how you choose to deal with them that makes your character a winning one.
however, that was 20 years ago. That priest has moved on to a different school in a different state, but every time I see him when he comes back into town I have this unquenchable thirst to wipe the court with him. LOL, Father has to be in his 60s now. But I would show no mercy! If he ever has the guts to pick up a racquet against me it will be a 6-0 6-0 absolute beatdown. So I guess there are some scars left from the situation.
