The program's first extended period of success came just after the turn of the century. Between 1900 and 1916, Nebraska had five undefeated seasons and completed a stretch of 34 consecutive games without a loss, still a program record. Despite a span of 21 conference championships in 33 seasons, the Cornhuskers didn't experience major national success until Bob Devaney was hired in 1962. In eleven seasons as head coach, Devaney won two national championships, eight conference titles, and coached 22 All-Americans, but perhaps his most lasting achievement was the hiring of Tom Osborne as offensive coordinator in 1969. Osborne was named Devaney's successor in 1973, and over the next 25 years established himself as one of the best coaches in college football history with his trademark I-form offense and revolutionary strength, conditioning, and nutrition programs. Following Osborne's retirement in 1997, Nebraska cycled through four head coaches before hiring state native Scott Frost in 2017.
