JMO, but the implementation of this proposal ought to come with guardrails and protocols. I don't see how tenable "my school doesn't have football anymore, but there's four adjoining districts that have it so I can choose wherever to play" is. Not sure, either, how that works without coaches/families (intentionally or unintentionally) running afoul of recruiting rules over time.
One other tiff is this: what exactly is the mechanism to help resurrect programs at schools that go through dormancy if this comes into effect?
Example: School 'A' cancels girls' basketball for 2022-2023, citing low numbers. Two sisters, underclassmen, opt to play for neighboring School 'B' and their GBK team. Summer 2023 rolls around -- School 'A' says "if we have n girls (e.g. 7) sign up, we'll bring back the program for the upcoming winter", 'A' is at 5 sign-ups. The two who played at neighboring school 'B' hold out and don't sign up to play for the school they're enrolled at (school 'A'.) 'A' ends up not fielding GBK for the second consecutive year ('23-24.)
...there's no way to prevent that in this proposal?
Springing off that example: what are the eligibility procedures for offseason activities if this comes to pass?
