The years from 1976 to 1991 that Tom Kimbrough spent as the head coach of Plano will go down in history as one of the greatest tenures in Texas high school football. His record as head coach was an incredible 173-28-5. Plano Senior had won more games than any school in the history of Texas high school football when he retired in 1991. Dave Campbell’s Texas Football named him one of the “Top Ten Most Memorable Coaches” over the last 50 years, which included Tom Landry and Darrell Royal as first and second, with only three other high school coaches in the Top Ten.
