In the last 20 years Gary Rankin is 250-29 as a high school football coach. In that time he was been to 13 state title games and captured 8 of them. I would love to rate Rankin's win/loss record over the last 20 years against any other high school football coach in the nation. Not the state but the nation. When Rankin leaves Alcoa he will leave as the winningest football coach in the history of Tennessee high school football, he will have won more state titles than any coach in this state's history, and Alcoa at that time will be alone at #1 when it comes to overall state titles by an individual school. His numbers speak for themself and for those that always say "he has talent" well I can name several schools that have talent and can't ever win at the rate Alcoa does.
Gary Rankin & George Quarles are in a class all by themselves as far as current high school football coaches in the state of Tennessee are concerned.
After that is when I would include the class of guys like Glen McAdams, David Martin, Buck Coatney, Jeff Morris, etc.
