Not many left. With the departures of Sean Callahan at Armwood, Corky Rogers at Bolles, and of course George Smith at STA, other than Castle and Garcia, I can't think of any. The old timers are gone. Joe Kinnan and Paul Maechtle (out of retirement and coaching Cardinal Mooney) also come to mind.
Castle and Garcia were easy, but I can't think of even one more.
