Flood offered Prince the job more than a week ago, sources said, but an interview for the New Orleans Saints running backs position slowed down the process.
Flood announced a series of other changes this morning, refilling his coaching staff after multiple offseason departures.
Linebackers coach Dave Cohen will be promoted as the defensive coordinator. Cohen moves into the role following Robb Smith's departure to the Tampa Bay Buccaneers.
Also announced, running backs coach Norries Wilson has been promoted to associate head coach and graduate assistant Anthony Campanile moves into a full-time offensive assistant coaching role.
During Prince's time at Kansas State, the Wildcats averaged 31 points per game in the three-year span. He most notably coached now Tampa Bay Buccaneers quarterback Josh Freeman to three straight impressive seasons before he declared early for the NFL draft.
Under Prince, Freeman threw for 8,421 yards and 44 touchdowns before becoming a first round pick.
Prior to putting Freeman in the NFL, Prince did the same at Virginia as Matt Schaub's offensive coordinator. Prince coached Schaub the final three years of his college career. He threw for 7,511 yards and 56 touchdowns under Prince.
During the eight-year span with Kansas State and UVA, Prince's offenses averaged 375 yards and 28.4 points per game. Prince's three starting quarterbacks – Schaub, Marques Hagans and Freeman – all moved on to NFL careers.
Though known for developing quarterbacks, Prince's background comes in offensive line. Prince coached exclusively offensive linemen for the first eight years of his career and played tackle at Appalachian State.
