As an alum I can assure you that OCS does no active recruiting. Are there kids who live out of district who go there? Yes. However it is for the environment of the school and its academics, not athletics. Their entire families go there and not all are athletes. 95% come to OCS prior to high school.
It's a fine line thing. Are they coming because they are "recruited" or are they coming because the public schools they are leaving have gone to poop?
When I was a kid, all the local high school baseball programs were coached by assistant football coaches, who half-assed baseball season as something to do until spring football started.
Then the local private school hired a real baseball coach who put together a good schedule and organized it like a real coach would. Next thing you know, that school had the best players in town and, of course, they were accused of recruiting them.
Did they recruit them or did the public schools F-up by not doing the sport justice? A few years later, one of the big public schools also hired a good coach and in a heartbeat they were getting the best players.
