Bryan Harsin is keeping Derek Mason in the SEC.
Per AL.com, the new Auburn coach is hiring the former Vanderbilt head coach to become the Tigers defensive coordinator.
Mason has previously served as a defensive coordinator at Stanford where he built the Cardinal into one of the top defenses in the country under David Shaw. His last season inn Palo Alto saw his defense finish 16th in the FBS in total yards allowed per game, giving up just 343.5.
His tenure at Vanderbilt started including two six-win seasons and trips to a bowl game, yet the Commodores fell apart the last two seasons, finishing 3-7 in 2019 and 0-8 this year, respectively.
