7. Bobby Dodd: 66.2% (1960-1966) — Georgia Tech
Despite his coaching career at Georgia Tech spanning from 1945-1966, Bobby Dodd’s stint from 1960-1966 (1960 being the benchmark year that we dubbed the modern era) still holds the highest winning percentage of any Yellow Jacket coach since. Playing a dual role of athletic director and head football coach, Dodd was given the nickname “The Bowlmaster,” leading the Yellow Jackets to 13 bowl games and winning nine of them. He additionally fostered a 31-game win streak from 1951-53 and helped Georgia Tech get recognized as national champions in 1953. His final six years did not see a losing record, and after Dodd stepped down as head coach, he kept his athletic director role for nine more years before officially retiring. In 1988, the Georgia Tech Stadium was named after Dodd.
