John Flynn is in his fourth season as the Jackrabbits’ offensive line coach after joining the South Dakota State University football staff in February 2012.
Flynn made an immediate impact during the 2012 season as the Jackrabbits more than doubled their average rushing total from the previous year, increasing from 83.5 yards per game in 2011 to 177.2 en route to their first of three consecutive berths in the Football Championship Subdivision playoffs.
Two of Flynn’s players, tackle Bryan Witzmann (first team) and Will Castle (second team) were all-Missouri Valley Football Conference honorees in 2012. Witzmann went on to receive first-team All-America honors from the Sports Network and second-team recognition from The Associated Press. Witzmann repeated both as an all-conference and All-America performer in 2013, and later earned an invitation to play in the College All Star Bowl.
In 2014, the Jackrabbits racked up their highest yardage total in the Division I era with an average of 435.1 yards of total offense per game, and their 31.8 points per game marked the most since 2008. Two of Flynn's pupils were honored by the MVFC as right tackle Trevor Greger was a first-team all-league selection and center Jacob Ohnesorge was an honorable mention pick.
Flynn arrived at SDSU after five seasons at his alma mater, Oklahoma, where he served first as a graduate assistant and later as offensive quality control assistant.
During his time as a member of Bob Stoops’ coaching staff, Flynn served in a variety of roles, including assistant offensive line coach for Sooner teams that played in five bowl games, highlighted by an appearance the 2009 BCS National Championship. Flynn also assisted in coaching the team’s running backs, tight ends and special teams units during his tenure at Oklahoma.
Three of the offensive linemen he coached — Trent Williams, Phil Loadholt and Duke Robinson — earned All-America recognition and later were selected in the National Football League Draft.
Prior to coaching, Flynn served as a coordinator for athletic academic services at Oklahoma, where he helped monitor the academic progress of more than 600 student-athletes.
As a player, Flynn lettered two times as an offensive lineman for Sooner teams that won Big 12 Conference titles in 2002 and 2004 and played in back-to-back BCS National Championship games.
