Crowton was reportedly offered a three-year contract at $500,000 a year. He was making $475,000 a year this season and had one year remaining on his contract at $500,000.
Crowton served as LSU’s offensive coordinator and quarterback coach for four years, and he captured a National Championship in his first year and posted a 40-13 overall record over the stretch.
“I appreciate all that Gary did for LSU during his four years with us,” said head coach Les Miles. “Gary helped us win a lot of games over the last four years, including a national championship. He’s an outstanding coach and a man of great character.
“We wish him and his family well in any of their future endeavors.”
While no names have been mentioned as a possible replacement, Miles said that the search for a new offensive coordinator would begin immediately.
