I think the reason is multiple factors (1) it is a boarding school, it takes kids from all over the country, can't tell me a kid from back country Ohio or Clemson would transfer to Bradenton, FL for 1 year and that somehow sway a perceived bias from going to OSU or Clemson. Kids aren't there long enough to even develop real friendships when you are talking about meeting someone for just a year; and (2) they have sooooo many D1 commits, it is pretty hard to think school a is favored over school b, they are spread out. Like currently out of the top 300 they have kids committed to Clemson, Bama, FSU, and Penn State.
We have had decent success off the top of my head I can think Hightower, sitkowski (was going to come until we backed off), St. Louis, Redding, Patchan, Fines and I might be missing 1 or 2.
