- Title:
- Defensive Passing Game Coordinator/Corners
Texas Tech, 1999
• Tim Duffie joined the Oklahoma State staff in March of 2013 and coaches the Cowboy cornerbacks. He coached the safeties from 2013-14. He was elevated to Defensive Passing Game Coordinator in 2023 while retaining his coaching duties at cornerbacks. Six of his 11 years in Stillwater have resulted in 10-win seasons.
• In 2023, Duffie’s group helped OSU rank No. 2 in the FBS with a defensive fourth down conversion rate of just 24%. Korie Black allowed only 16 receptions to rank No. 3 among FBS cornerbacks with at least 350 coverage snaps.
• Duffie’s 2022 cornerbacks helped OSU finish the season ranked among the top three Big 12 teams in pass efficiency defense and among the top three FBS teams in third down defense.
• In 2021, both of OSU’s starting cornerbackers earned All-Big 12 honors from the league’s head coaches as Jarrick Bernard-Converse was on the first team and Christian Holmes was on the second team. It was just the second time ever and the first time since 1997 that both of OSU’s starting cornerbacks were on the coaches’ all-conference team. As a team, the Cowboys wrapped up the year ranked No. 1 in the Big 12 in passing efficiency defense.
• Duffie coached Rodarius Williams to second-team All-Big 12 honors in 2020 as he set the OSU school record for consecutive starts at 48 games. Pro Football Focus graded him as the No. 20 overall FBS cornerback in the 2020 season and as the No. 4 FBS cornerback in tackling ... According to PFF, he was the only FBS cornerback to face at least 240 coverage snaps (he faced 255) and allow no more than 10 catches in 2020. Under Duffie’s guidance, Williams wrapped his career ranked sixth in school history with 31 career passes broken up.
• Duffie coached A.J. Green to second-team All-Big 12 honors in 2018 and again in 2019. Green and fellow starting cornerback Rodarius Williams combined to break up 19 passes in 2018 - representing half the team’s overall total.
• Thanks in part to the downfield coverage provided by Duffie’s cornerbacks, OSU led the Big 12 and ranked 10th in the FBS with 3.00 sacks per game in 2018.
• Starting a freshman and a sophomore at cornerback in 2017, OSU led the Big 12 and ranked 15th nationally in passes intercepted. A.J. Green provided one of the signature moments of the season when he picked off a pass in the end zone in the waning seconds to seal the Cowboys’ win at No. 24 Iowa State. Green tied for No. 2 in the Big 12 with four interceptions.
• Duffie’s cornerbacks played a role in OSU leading the Big 12 in turnovers gained in 2016.
• In 2015, Duffie coached first-team All-Big 12 cornerback Kevin Peterson, who was a semifinalist for the Jim Thorpe Award, presented to the nation’s top defensive back.
• Duffie’s troops helped Oklahoma State rank in the top 10 nationally in turnovers gained in both 2013 and 2015.
• In his first season in Stillwater, OSU showed significant improvement by holding opponents to 21.6 points per game, down from 28.2 points per game the year prior to his arrival.
• OSU finished 2013 ranked in the top 25 nationally in scoring defense (19th), turnovers gained (fifth), passes intercepted (third), red zone defense (seventh), pass efficiency defense (sixth), tackles for loss (16th) and third-down conversion defense (seventh).
• The 2013 Cowboys ranked third in school history in yards per pass attempt defense and third in pass efficiency defense. OSU’s 21 interceptions in Duffie’s first year were the sixth-highest total in school history and its 60 pass breakups ranked seventh.
• Duffie coached Daytawion Lowe to second-team All-Big 12 honors 2013.
• In 2014, one of Duffie’s pupils, sophomore safety Jordan Sterns, became the first OSU underclassman to record 100 tackles in a season in 18 years. Under Duffie’s coaching, Sterns earned All-Big 12 honors in both 2015 and 2016.
• Duffie came to Stillwater after spending the 2012 season coaching the secondary at Wake Forest. In his lone season at Wake, the Demon Deacons led the Atlantic Coast Conference and ranked 25th nationally in turnover margin.
• Prior to his time at Wake Forest, Duffie spent 2008-11 at Colorado State. He was cornerbacks coach from 2008-10 and then coached the entire Rams secondary in 2011. He served as CSU’s primary recruiter for the state of Texas.
• While in Fort Collins, Duffie was heavily involved in recruiting much of CSU’s top talent, including Crockett Gillmore, an all-conference performer in his first season as a tight end in 2011, Weston Richburg, a 2010 freshman All-American, and Austin Gray, a 12-game starter at safety as a freshman in 2011. In his first year at the reins of the Rams full secondary in 2011, Duffie was instrumental in helping CSU finish the regular season ranked 14th in the nation by allowing only 179.6 passing yards per game.
• Duffie broke into coaching at UTEP, where he served as a graduate assistant coaching linebackers in 2000 and then safeties in 2001. He was elevated to his first full-time position coaching the Miners safeties from 2002-03 then served as UTEP’s linebackers coach from 2004-06 and back to safeties in 2007.
• During his time at UTEP, he coached nine all-conference athletes, the 2004 Western Athletic Conference Defensive Player of the Year in Robert Rodriguez and a second-round NFL draft choice in Thomas Howard. Howard went on to become an everyday starter for the Oakland Raiders and Cincinnati Bengals.
• As a two-year starter and four-year letterwinner playing for coach Spike Dykes at Texas Tech, Duffie had 202 tackles, six tackles for loss, one sack, three passes broken up and two interceptions from 1996-99. As a senior, he started all 11 games and racked up a single-game career-high 18 tackles at Missouri. A second-team all-state selection at Jefferson High School in his hometown of Jefferson, Texas, Duffie earned Cypress Valley Player of the Year honors and was an all-district performer on three occasions. In addition to football, he lettered in basketball, baseball and track.
• Duffie earned a bachelor’s degree in exercise and sports science from Texas Tech in 1999 and a master’s in education administration from UTEP in 2002.
• Duffie and his wife, Autumn, have two sons together, Memphis and Manhattan. He also has a son, Timias.
