I think OP is right. I see it even among the kids at our private Christian school, which requires a recommendation letter from your pastor/preacher/priest attesting to your regular church involvement. Many of the kids now pick one sport and play it year-round. That means a lot of kids are playing tournaments out of town on weekends and missing church. We are facing that point as our boys are considering joining an AAU basketball team composed of the kids from their high school team so they keep developing year-round. We'll have to be choosy about what tournaments they participate in. I'd like to limit it to in-town tournaments with Sunday games limited to afternoon (after morning service). Hopefully there will be enough of those options available to make it worthwhile. We definitely will not join a team where they are constantly travelling and/or missing Sunday morning services.
I'd like to add that I have no illusions that either of my boys will be professional or even D1 basketball players. However, there are a number of great STEM oriented colleges with DII and DIII basketball teams. We don't need athletic scholarships, but you can actually get IN if you are an athlete. When you are facing 5-10% admissions rates, sports can be the way in for a white male without a woke sob story to tell. Consistently the kids from our school who get into the best colleges are the athletes. MIT, Harvard, the service academies, or even just good engineering colleges like School of Mines are where our best student athletes are going. Without sports, many of them would be looking at holistic admissions (the top 10% is only 5-8 kids per grade, mostly female) at A&M and sip, with out-of-state SEC schools as the plan B.
