11. Bud Wilkinson
Bud Wilkinson would no doubt have finished much higher up this list if he hadn’t retired at the relatively young age of 47. The coach single-handedly transformed the fortunes of the Oklahoma Sooners in the post-war era, claiming three national titles in the 1950s alone. Wilkinson also achieved a record-breaking winning streak before swapping the football stadium for the political arena.
10. Bobby Bowden
Bobby Bowden started his head coaching career at South Georgia State in 1956, but it was 20 years later that he began to truly make his mark. After taking over at underperforming Florida State, Bowden led the Seminoles to two national titles and 14 consecutive top-five seasons. He also coached two Heisman Trophy winners before retiring in 2009 aged 80.
