Is Oak Hill an actual high school team?
As opposed to programs like Prolific Prep?
According to Wikipedia, it's a private Baptist-affiliated school that boards about 98% of their 150 or so students, and the basketball players have to earn qualifying grades to play and get diplomas, etc. Since they travel so much during hoops season, they have tutors and (I would assume) teachers that accompany them in their travels.
Since they play so few games in Virginia, and recruit worldwide (zero idea how much financial help they give, or for what reasons), the traveling team is not eligible to play in Virginia state playoffs, but most (or maybe even all) high school associations allow member teams to play against them without any penalty or sanctions.
It seems they used to have a local team, but I can't find any evidence of that now... I do remember hearing awhile back about one of their kids who played three years with the local team, and got so good he played with the national team his senior year... Can't remember who it is, tho.
Due to the 18 years I lived up in Oregon and that national-level Les Schwab holiday tourney they have up there, I've gotten to see the Oak Hill Warriors up-close for some 18-20 games, including their single Oregon loss to eventual 2010 CA state champ Westchester of LA. Now THAT was wonderful basketball... At the time, both teams were ranked in the Top 5 nationally... And they PLAYED like it!
