“Why not let everyone else sports to stay healthy and strengthen their immune systems, as well as get outside (where it's warm enough) and get the vitamin D they need?”

I’m all for letting people be outside freely by themselves and in isolated social groups. I’ve spent huge amounts of time exercising in parks in the sun outside during this thing for the reasons you mention.

Team sports where you get a bunch of unrelated people together in one place breathing hard and folks probably socializing after the game afterward seems more problematic.
