Personally, I think that private schools playing with public schools is a good thing. A lot of states actually are in that space. If your ultimate goal is to win a state championships then, yeah, maybe keep it at public schools only. If your goal is to play at the top level of competition and prepare you for the next level, let the private schools in. College teams - especially at the D1 level - are handpicked teams. A decade or so ago, Phoebus played Dematha as they wanted to play top talent. I think Hayfield played Good Counsel this year. The top public schools are actively seeking private schools for top competition. Why not make it happen more often in-state?
