Chris Phillips is always brought up as a "what if". Jesse Thielke (had Greco aspirations), Destin McCauley, John Meeks, Ben Whitford, Brooks Black, Lance Benick, Chase Singletary, Gavin Teasdale, Joey Silva were hammers in HS that never AA'd at the D1 level.
Hopefully Braxton Amos can get healthy and finish his career strong next year so he does not end up on this list.
