The program had ten head coaches in its first 14 seasons, but A. R. Kennedy took the position in 1904 and held it for the next seven highly successful seasons, through 1910. Kennedy's overall coaching record at Kansas was 52–9–4. This still ranks as the most wins for any Kansas head coach, and puts him fourth at the school in terms of winning percentage (). Kennedy's best season was 1908, when the Jayhawks posted the school's second ever undefeated season (9–0) and won the school's first major conference championship, in the Missouri Valley Intercollegiate Athletic Association. KU has not had another perfect season since 1908. Kennedy was also one of the best performing coaches for Kansas in the Border War (as of 2007 called "Border Showdown") between Kansas and Missouri, going 4–1–2 (.714) against MU as a coach and 7–1–2 (.800) against MU cumulatively as a coach and player.
