I loved playing basketball, too. But then in high school I could choose between taking advanced math classes or basketball PE, which was required to play on the basketball team. That kind of choice shouldn't be the kind of choice a high school student should have to make.

There were many more example of trade offs like this, almost all of which undermined any ostensible focus on education.

These kinds of things have nothing to do with whether playing sports (on a team or not) can be a positive experience or is good for people.
