15. Bernie Bierman
Underrated coach Bernie Bierman enjoyed stints at Montana, Mississippi State and Tulane during the 1920s and 1930s. But he established himself in the pantheon of greats when he guided Minnesota to five national titles in just eight years. And he would no doubt have added to that tally his career not been interrupted by the Second World War, in which he served as a colonel.
14. Barry Switzer
Barry Switzer is one of just three coaches to have won both a college football national title and a Super Bowl in the 1970s and 1980s. Renowned for his offensive style of play, Switzer earned his ring with the Dallas Cowboys and three NCAA crowns with Oklahoma. He also boasts one of the highest winning percentages in college football history and coached nine top three-placed teams.
