In his lone season at Michigan State, the Spartans were among the top-40 teams in college football with 2.42 sacks per game. Derrick Harmon was fifth among Big Ten interior linemen and ninth among all linemen in the league with 20 defensive stops on run defense this season and his 80.1 grade on run defense was 15th among all FBS interior linemen this season (min. 200 rush defense snaps) while teammate Simeon Barrow Jr. was in the Top-50 in the category as well.
During his time at Stanford, Reynolds coached four NFL Draft picks on the defensive line, including Solomon Thomas, who was the highest defensive player drafted in school history at No. 3 overall in 2017 by the San Francisco 49ers. Thomas also won the Pac-12's Morris Trophy, given to the league's top lineman, and garnered All-America honors from the Football Writers Association of America (second team), USA TODAY (second team) and Associated Press (third team).
Reynolds instructed defensive tackle Harrison Phillips throughout his Cardinal career, and the All-American was selected 96th overall by the Buffalo Bills in the third round of the 2018 NFL Draft. Phillips led Stanford in tackles with 103, the most of any defensive lineman in the nation. Among those 103 tackles were a team-best 17 for loss and 7.5 sacks, as well as two forced fumbles. He was a second-team All-America choice by the Football Writers Association of America, and the Associated Press voted him third-team All-America. Phillips just completed his fifth season in the NFL.
Reynolds also mentored defensive end Casey Toohill (2020 seventh round, No. 233 overall, Eagles) and defensive end Thomas Booker (2022 fifth round, No. 150 overall, Texans) in Palo Alto.
Stanford ranked in the Top-25 nationally in sacks per game in 2016 and 2018.
After originally spending a season as a defensive assistant at Stanford in 2014, Reynolds went to Oklahoma in 2015 to coach the Big 12 Champion Sooners before returning to the Cardinal in 2016. In his lone season in Norman, Reynolds helped OU to a berth in the College Football Playoff while coaching first-team All-Big 12 defensive lineman Charles Tapper, who was selected in the fourth round of the 2016 NFL Draft by the Dallas Cowboys.
Reynolds' coaching resume includes more than a decade of coaching in the NFL with the Colts (2002-06), Dolphins (2007) and Vikings (2009-13).
His most recent NFL experience came under the tutelage of Leslie Frazier with the Vikings. Reynolds spent five seasons (2009-13) as the assistant defensive line coach at Minnesota, working with All-Pro defensive linemen Jared Allen and Nick Williams, and his unit helped the Vikings lead the NFL in sacks in 2011 with 50.
Reynolds spent the 2007 season with the Miami Dolphins as a defensive line coach and worked with NFL Hall of Famer Jason Taylor, who had 11 sacks and 16 TFLs that season to earn Pro Bowl honors for the sixth time in his career.
Reynolds coached the previous five seasons in Indianapolis as a member of Tony Dungy's coaching staff, where he served as a defensive quality control coach when the Colts won Super Bowl XLI over the Bears. Reynolds worked alongside Colts defensive line coach John Teerlinck as the team reached the NFL Playoffs each season during Reynolds' five-year tenure in Indianapolis (2002-06). He also worked with seven-time Pro Bowler and two-time defensive player of the year Dwight Freeney with the Colts.
Prior to coaching in the NFL, Reynolds worked as a defensive tackles coach at Indiana in 2001. His first collegiate coaching experience came at his alma mater, Wake Forest, where he served as a graduate assistant in 1997-98 and outside linebackers coach from 1999-2000.
Reynolds began his coaching career in 1995 at Brookland-Cayce High School where he served as an assistant coach and strength and conditioning coach.
He earned four letters as a linebacker and special teams contributor at Wake Forest from 1990-93, graduating in 1994 with a bachelor's degree in communication. He also earned a master's degree in liberal studies from Wake Forest in 1999.
Reynolds, who is originally from Aiken, South Carolina, is married to Emon and the couple has four children.
