Personally I think there is a lot of value in HS and college sports. (Speaking generally, because, of course, there are exceptions.)
There’s camaraderie, friendships, mentorships self-discipline, leadership opportunities, skill, confidence and a host of other things learned by being part of a team. Yes, any team. But sports are natural, and preferred, for some. I know my son had a lot of energy to get out, so sports were a natural outlet for that.
I remember once, asking our pediatrician, if my son should quit sports, since he’d been injured quite a bit. He said, “Absolutely not, sports are great for kids”. He obviously believed in their value, despite their risks.
My son was also shy, but still thrived at being part of various teams. A nice balance can be developed between keeping to oneself and mingling with others. Not a bad skill to learn for much of life, either, maybe especially for kids today (how to not “run with the crowd” but still maintain respect), but that’s getting away from the main topic, we’ll have to save it for another time.
