- Title:
- Defensive Line
Greg Richmond returned to Oklahoma State in December of 2025 after previously coaching the Cowboys from 2007-08 and from 2018-23. He also played defensive end for OSU from 2000-03.
Richmond came to OSU from North Texas, where he coached defensive ends in 2025. In his lone year at UNT, he was part of a staff that helped improve the Mean Green by nearly 10 points per game in scoring defense, by 90 yards per game in total defense and by more than 100 yards per game in passing defense. The 2025 UNT defense ranked among the top 25 in the FBS in fumbles recovered (No. 3), turnovers gained (No. 4), passing yards allowed (No. 8), passes intercepted (No. 14) and passing efficiency defense (No. 14).
Prior to coming to UNT, he coached defensive ends at Sam Houston in 2024.
Â
In his one year with the Bearkats, Richmond helped SHSU finish 22nd in FBS in total defense, 13th in passing defense and 14th in red zone defense. He also coached first team All-CUSA honoree Chris Murray and helped the Bearkats tie for 11th in the FBS in fumbles recovered and second in Conference USA in sacks.
Richmond helped the Bearkats finish the year 10-3 and earn the first bowl victory in program history with a 31-26 win over Georgia Southern in the New Orleans Bowl.
An Oklahoma State product, Richmond was on staff at his alma mater for the 2018-23 seasons. He shared the defensive line coaching duties from his return in 2018 through the 2021 season before taking over those duties solely in 2022.
During that stint in Stillwater, Richmond helped OSU rank among the national leaders in tackles for loss three straight seasons (2020-22). He produced a first-team All-Big 12 defensive lineman in two of those six years and had a total of four defensive ends earn All-Big 12 honors.
In 2021, Richmond’s defensive line helped OSU lead the nation and set the school record with 57 total sacks and finish No. 2 in the FBS with 114 tackles for loss. Collin Oliver was a freshman All-American who finished No. 7 in the FBS and set an OSU freshman record with 11.5 sacks on the season.
In a shortened 2020 season, Richmond’s defensive line unit helped the Cowboys rank ninth nationally with 8.1 tackles for loss per game and No. 16 with 3.0 sacks per game.
With Richmond on staff, the OSU defense showed significant improvement from 2018 to 2019. In 2018, the Cowboys allowed an average of 32.5 points and 452.5 yards per game, but in 2019, those numbers improved to 26.8 points per game and 412.3 yards per game. Then in 2020, those numbers improved again to 23.5 points per game and 379.0 yards per game.
In his first year as a coach at OSU in 2018, the Cowboys led the Big 12 and ranked 10th nationally in sacks while also finishing second in the league and 20th nationally in tackles for loss.
Defensive end Jordan Brailford earned first-team All-Big 12 honors in 2018 after leading the league in sacks per game and ranking fifth in the conference in tackles for loss.
The Cowboys of 2018 had 39 sacks as a team, a mark that ranks among the top 10 in school history. Of those 39 sacks, 26.5 came from defensive linemen. In addition to their work on the field, a trio of Oklahoma State defensive linemen earned first-team Academic All-Big 12 honors in 2018 with Richmond serving as their position coach.
From 2015-17, Richmond coached the defensive line at Fairmont State in West Virginia, where he helped the team to a three-year record of 24-9 and back-to-back eight-win seasons for the first time in more than 50 years.
In 2017, Fairmont State led the Mountain East Conference and ranked No. 12 nationally by allowing only 15.6 points per game. The Falcons also led the league in total defense, defensive touchdowns, passes intercepted, pass efficiency defense and turnovers gained.
Just prior to that 2017 campaign, he served as a minority coaching intern with the New York Giants, where he assisted with the defensive line.
As a unit, Richmond’s 2016 defensive line ranked second in the league and 22nd in the country in sacks – averaging more than three sacks per game (3.08). The FSU defense also locked down on opposing rushing attacks, as the Falcons allowed just 95.5 yards per game on the ground and gave up just 15.1 points per game during the regular season.
Richmond’s top pupil at Fairmont State was defensive end Quincy Redmon, who put together one of the most decorated seasons for a defensive lineman at FSU during the 2016 season. Redmon earned honorable mention All-America honors and was named the Mountain East Conference Defensive Player of the Year after racking up 52 tackles, 12 sacks, three fumble recoveries and two forced fumbles as a junior. For his efforts, Redmon was also a finalist for the Cliff Harris Award, which honors the top defensive player in small college football. Redmon became the first All-America defensive lineman at Fairmont State since David Hill in 2008.
In 2014, Richmond was the defensive line coach at Tahlequah High School (Okla.) after spending the 2012 and 2013 seasons working in the private sector away from football.
From 2010-12 Richmond served as the defensive line coach at Northeastern State University in Tahlequah, Okla.
Â
Highlighting his three seasons at Northeastern State were a Lone Star North Conference Championship in 2010 and an appearance in the Mineral Water Bowl in 2011.
During the summer of 2011, Richmond worked for the Minnesota Vikings as a minority coaching intern with the defensive line.
A standout at Oklahoma State during his playing days, Richmond was a four-year Cowboy letterman from 2000-03. A first-team All-Big 12 selection in 2003, Richmond remains on OSU’s single-season and career top 10 lists for quarterback sacks to this day. After graduation, Richmond signed as a free agent with the Philadelphia Eagles, where he stayed until 2007.
Immediately after his NFL career wrapped up, he returned to Stillwater to serve as an assistant director of strength and conditioning from 2007-08 and from that point forward held positions coaching defensive line at both the high school and college level.
Richmond graduated from Oklahoma State in December of 2003 with a degree in hotel and restaurant administration before getting his master’s in educational leadership from Langston University in 2012. He and his wife Jennifer have three sons, Jaylen, Jacoby and Jamar.
