This whole transferring from school to school issue is only one piece to a bigger puzzle. Kids are moving around with and without their parents and that's all that the public sees.
If you look a little deeper you'll find the "friends of the program" factor that's never mentioned. In fact it happens in such a way that if you're a fan of the team it comes off that the community has taken you in.
Here's how it works, a kid is recruited to come to a school. The first place the kid needs is a residence in the school district. Low and behold the first friend of the program happens to have a rental house or apartment available. Let's say the parent of the player comes and needs a job. Another friend of the program happens to need some help at their business. If there are issues with the legality of move and eligibility, no problem, another friend of the program happens to be an attorney or has an attorney on retainer. In some cases the friends of the program who are in the legal field are reading the KHSAA bylaws and updates to find loopholes.
In the meantime teams who are doing this continue to win, their game attendance continues to grow, others want to donate as either athletic boosters or become a friend of the program. The district justifies paying a coach an administrator's salary (even if the coach isn't a certified teacher). And the wheels keep turning.
The KHSAA doesn't have the manpower to police this and they know that this opens a much larger can of legal worms.
I know some folks are reading this and laughing and probably saying it's a conspiracy theory and that's ok. But the next time a star player just happens to move in listen closer in the bleachers and concession stand line.
