Back in the late 80's, PN-G was coached, as HC, by one of the best offensive line coaches in the state of Texas, Butch Troy. Not very successful, though, as a HC. His last year, 1988, Troy went 1-8. Danny Malone came in the next year and went 12-2 and, if I recall right, was one game from playing in the State Championship. So, different coach, same bunch of kids. Was it coaching that made the difference? IMO, yes.
