Grimes spent the past three seasons as offensive coordinator at BYU, which went 11-1 in 2020 and boasted the nation's No. 3 scoring offense (43.5 PPG) and was the leader in yards per play (7.84). He replaces Larry Fedora, who was fired after a year with Baylor, which ranked ninth in the Big 12 in both scoring offense (23.5 PPG) and total offense (310.2 yards per game).
"First of all, Jeff is a high-quality person," Baylor head coach Dave Aranda said in a prepared statement. "He is a family man. He is a true ball coach and a fundamental teacher of the game. He coaches a physical offense built on explosive plays in both the pass and run game. There is a strong identity in what he does. We will be building to that vision, and I know he will hold our staff and players accountable to that standard. I am excited to welcome Jeff, Sheri and their family to Baylor."
A native of Garland, Texas, Grimes played offensive tackle at UTEP and began his coaching career in his home state. The 52-year-old has extensive experience coaching the offensive line, making stops at LSU, Virginia Tech, Auburn, Colorado, Arizona State and Boise State.
Grimes this year was a finalist for the Broyles Award, which goes to the nation's top assistant coach.
