BYU found its next offensive coordinator, announcing Thursday that LSU assistant coach Jeff Grimes will replace former coordinator Ty Detmer and take over the Cougars' offense.
Here's a look at the football career of Grimes:
1993-94, Riverside (Texas) High School
Grimes served as the team's offensive coordinator and offensive line coach in his first coaching gig.
Grimes was a graduate assistant with the Owls under Ken Hatfield during a season in which Rice went 2-8-1 in the now-defunct Southwest Conference.
1996-97, Texas A&M
After one year at Rice, Grimes moved on to Texas A&M, again as a graduate assistant. During his first season, the Aggies lost to BYU 41-37 in the Pigskin Classic. Under head coach R.C. Slocum, Texas A&M went 15-10 in Grimes' two seasons with the program, including a 9-4 mark in 1997 and a loss in the Cotton Bowl.
Grimes' first time serving as a position coach in college came at the Division III level when he served for two seasons as offensive line coach for Hardin-Simmons (Abilene, Texas).
2000, Boise State
Grimes jumped to the Division I level in 2000, where he served as offensive line coach under Dirk Koetter, now the head coach of the Tampa Bay Buccaneers. The Broncos won the Big West championship with a 10-2 overall record in their final year in the league before jumping to the WAC, while Koetter left to become head coach at Arizona State after the season.
Boise State led the nation in scoring that year, averaging 44.9 points per game, and was second nationally in total offense at 496.3 yards per game. The Broncos were also 30th in rushing yards, averaging 174.3 per game.
2001-03, Arizona State
Grimes joined Koetter at the Pac-10's Arizona State, serving as the Sun Devils' offensive line coach and running game coordinator for the next three years. Koetter served as the offensive play caller, and Arizona State went 17-20 during Grimes' three years in Tempe.
His best season as run game coordinator came in 2001, when the pass-heavy Sun Devils averaged 167.1 rushing yards per game, 45th nationally. Following that season, four of Grimes' offensive linemen were taken in the 2002 NFL draft, including tackle Levi Jones (10th overall selection), Scott Peters (fourth round), Travis Scott (fourth) and Kyle Kozier (seventh).
Grimes' next stop came in familiar Provo, where he served as offensive line coach for Gary Crowton for one year, then two seasons under Bronco Mendenhall.
Grimes had his biggest success come under Mendenhall in 2005 and 2006, as the Cougars were No. 13 in the country in total offense (462.4 ypg) and No. 24 in scoring offense (33.0 points per game) in 2015. That increased the next year when BYU finished the year No. 4 in total offense (465.5 ypg) and fifth in scoring offense (36.8 ppg). Curtis Brown rushed for 1,000 yards in both 2005 and 2006.
The Cougars' last offensive lineman to be taken in the NFL draft, Scott Young in 2005, played under Grimes. He also coached several other offensive linemen who spent time in the NFL, including Dallas Reynolds, Travis Bright, Lance Reynolds Jr. and Ray Feinga.
Grimes joined Dan Hawkins' program in Colorado for two years, after the two worked together as assistants at Boise State in 2000. Grimes was the assistant head coach, running game coordinator and offensive line coach for the Buffaloes.
Colorado finished his first year with the program 69th in the country in rushing offense (144.2 ypg), one spot below BYU, and that dropped to 87th (124.5 ypg) in 2008.
Grimes served as offensive line coach under head coach Gene Chizik for the next four years at Auburn. In 2009, the Tigers set several school offensive records, including points in a season (433) and total yards of offense in a season (5,613). Auburn finished the year 13th nationally in rushing (212.0 ypg).
The Tigers then won a national title in Grimes' second season with the program. They broke the previous year's program records for points in a season (577) and total yards of offense in a season (6,989). That year, Auburn finished No. 7 in the country in scoring (41.2 ppg), No. 5 in rushing offense (284.8 ypg) and No. 7 in total offense (499.2 ypg).
The Tigers went 3-0 in bowl games and 33-19 overall while Grimes was there. Grimes coached two Auburn offensive linemen who were taken in NFL drafts during his tenure: tackle Lee Ziemba (seventh round, 2011) and tackle Brandon Mosley (fourth, 2012).
2013, Virginia Tech
Grimes served one year under longtime coach Frank Beamer as the team's running game coordinator and offensive line coach. The Hokies struggled offensively that year, averaging 119.8 ypg (108th nationally) in rushing offense and 19.1 ppg (104th).
Grimes has spent the past four years as the running game coordinator and offensive line coach for LSU, under Les Miles (2014-16) and Ed Orgeron (2016-17).
During his four years at the SEC institution, LSU has had one of the nation's top rushing teams. The best season came in 2015, when the Tigers averaged 256.8 ypg on the ground No. 7 nationally. They have been in the top 30 the other three years: 224.5 ypg (25th) in 2015, 233.1 ypg (21st) in 2016 and 210.8 ypg (30th) this season.
LSU has also produced four straight 1,000-yard rushers under Grimes, including Leonard Fournette in 2014 (1,034 yards, 10 touchdowns) and 2015 (1,953, 22), then Derrius Guice in 2016 (1,387, 15) and 2017 (1,153, 11).
Grimes has had three offensive linemen he coached at LSU taken in the NFL draft, including tackle Jerald Hawkins (fourth round, 2016), guard Vadal Alexander (seventh, 2016) and center Ethan Pocic (second, 2017). A fourth O-lineman, La'el Collins, was a projected first-round prospect who went undrafted — a police investigation right before the draft caused him to drop, though he was never charged — has become a starter with the Dallas Cowboys.
Grimes played offensive tackle at UTEP for four seasons from 1987 to 1990, earning letterman honors each season. Koetter was his offensive coordinator three of those seasons, and former BYU offensive lineman and grad assistant Andy Reid, now the Kansas City Chiefs head coach, was Grimes' offensive line coach in 1987 and 1988. He went to training camp for the Los Angeles Raiders and San Antonio Riders of the World Football League before moving on to coaching.
