I don't think Team 91 and the other teams up there are doing this. I think MD teams are into this 1) to try and keep up with the NY teams and 2) because public schools are so awful that most lax kids go private. The holdback thing is big among privates in all sports.
Spoken like a parent who doesn't know what he's talking about. First, the reclass thing is much more prevalent in PA and the NE. Second, Team 91 Crush has at least two reclassed kids, so it happens everywhere. Three, kids reclass for multiple reasons, but it's not because the Crabs can't compete without them.
Generally speaking, parents who send their kids to private schools have higher incomes. For whatever reason, it happens less often in NY partly because those parents generally speaking make less and thus private school is a less attractive option.
