The official word came a day after news reports from Baton Rouge and elsewhere tabbed Grimes as BYU’s new play-caller.
“I am so grateful for the opportunity to work, once again, at BYU. It is a special place, filled with extraordinary people and a rich football tradition,” Grimes said in a release from the school. “I recognize that with this position comes a great deal of responsibility to all of Cougar Nation. I not only welcome this, but consider it a privilege.”
Grimes has held offensive line positions at Boise State, Arizona State, BYU, Colorado, Virginia Tech, Auburn and LSU since 2000.
He coached the Cougars’ offensive line in 2004-06. He coached at Auburn for four seasons, including for its 2010 national championship team, and has been the offensive line coach and run-game coordinator at LSU for four seasons.
Grimes takes over for former Heisman Trophy winner Ty Detmer, who ran BYU’s offense for the past two seasons but was relieved of his duties after a historically bad showing in 2017.
Detmer — who had no college coaching experience when hired in 2015 — was relieved of his duties as offensive coordinator in November.
“One of Grimes’ first duties will be completing his offensive staff for the Cougars,” the release said.
