On top of that, go look at the facilities at Oak Ridge, Alcoa, Maryville, Farragut, Hardin Valley, Bearden, Science Hill, DB, Fulton, Greeneville among others and tell me which private school has better facilities.
Kids go where there are quality coaches and a winning program. My old high school used to be really good at basketball but are terrible now because kids don't want to play for the coach.
