Ben Sirmans enters his 14th NFL season as an assistant coach in 2025 and his 10th with Green Bay as the team's running backs coach. Originally named to his position on Feb. 17, 2016, and retained by Head Coach Matt LaFleur on Jan. 31, 2019, Sirmans previously spent four seasons with the St. Louis Rams (2012-15) after 16 seasons in the college ranks.
In 2024, Sirmans helped guide RB Josh Jacobs to Pro Bowl recognition as Jacobs led the team with 1,329 rushing yards and a career-best 15 TDs on 301 carries (4.4 avg.), the most rushing yards, rushing TDs and total TDs (16) by a Packer in his first season with the team. Jacobs ranked No. 6 in the NFL in rushing yards, No. 4 in rushing TDs and No. 6 in yards from scrimmage (1,671), becoming just the fourth player in team history to clear the 1,300-yard rushing mark and just the second Packer to register 1,600-plus scrimmage yards and 15-plus scrimmage TDs in a season. Sirmans also worked with second-year RB Emanuel Wilson, who posted a career-high 502 rushing yards and a career-best four rushing TDs on 103 attempts, an average of 4.9 yards per carry that ranked No. 8 in the league among RBs with 100-plus attempts in 2024.
Sirmans worked with RB Aaron Jones for Jones' first seven seasons in the league (2017-23) as he became the first player in NFL history to post 5,000-plus rushing yards (5,940), 45-plus rushing TDs (45), an average of 5.0-plus yards per carry (5.04), 250-plus catches (272), 2,000-plus receiving yards (2,076) and 15-plus receiving TDs (18) in his first seven seasons. Jones finished the 2023 regular season with three straight 100-yard rushing games and added two more in the playoffs, becoming the first player in team history (including postseason) to register five consecutive 100-yard rushing games. Jones joined Ahman Green (2000-04) as the only running backs in team history to post 30-plus receptions and a receiving TD in five consecutive seasons (2019-23).
In 2022, Sirmans worked with Jones as he posted 1,121 rushing yards on 213 carries, a 5.26-yard average that ranked No. 2 in the league among RBs. Jones added a career-high 59 catches, the most by a Green Bay RB since Green (62) in 2001. Sirmans also tutored RB AJ Dillon, who rushed for a career-high seven TDs along with 770 yards, one of only two running backs in the league (Steelers RB Najee Harris) to rush for 750-plus yards and play in all 17 games in both 2021 and 2022. In 2021, Sirmans mentored Jones (1,190) and Dillon (1,116) as they became only the second RB duo in team history to both register 1,100-plus yards from scrimmage in the same season, joining RBs John Brockington (1,270) and MacArthur Lane (1,106) in 1972. Jones finished with a career-high six receiving TDs in 2021, the most in a season by a Green Bay RB since Johnny "Blood" McNally had 11 in 1931.
Under Sirmans' guidance in 2020, Jones earned his first career Pro Bowl selection after recording 1,104 yards on 201 carries with nine TDs and a franchise-record average of 5.49 yards per rush attempt (min. 200 att.), joining Green (2000-01) as the only Packers with 1,000-plus rushing yards, nine-plus rushing TDs and 45-plus receptions in back-to-back seasons. In 2019, Sirmans tutored Jones, who had a career-best 16 rushing TDs, which was tied for the most in the NFL in '19 and was the second most in franchise history behind FB Jim Taylor (19 in 1962). Jones posted 1,084 rushing yards on 236 carries (4.6 avg.), the first 1,000-yard rusher for the Packers since RB Eddie Lacy in 2014, while his 236 attempts were the fewest carries needed by a 1,000-yard rusher in team history since Brockington in 1971 (1,105 yards on 216 carries). Jones (49) and Jamaal Williams (39) were the only running-back duo in the NFL to both have 35-plus receptions and multiple receiving TDs in 2019. As a group, Sirmans' backfield combined for the most receptions (101) by Green Bay RBs/FBs since 2006, the most receiving yards (881) since 2005 and the most receiving TDs (eight) since 2003.
Sirmans' third season in Green Bay saw him help guide the Packers to 1,667 rushing yards on 333 attempts, an average of 5.01 yards per carry that was the second-best mark in team history and ranked No. 2 in the league in 2018. Jones led the NFL (min. 100 att.) in yards per carry (5.47) in '18, the first Packer to lead the league in the category since the NFL went to a 16-game schedule in 1978. In 2017, Sirmans worked with Williams and Jones as they became the first rookie duo in franchise history to both rush for 400-plus yards in a season. Williams started seven contests and posted a team-high 556 yards rushing, the fourth most by a rookie in team annals, and 818 yards from scrimmage, the fifth-best total by a rookie RB in team history,
Jones played in 12 games with four starts in 2017 and rushed for 448 yards and four TDs on 81 carries, an average of 5.53 yards per carry that was good for No. 6 in franchise single-season history (min. 75 att.). Among RBs with 75-plus attempts, his rushing average ranked No. 2 in the league behind only Saints RB Alvin Kamara (6.07). Jones registered two 125-yard rushing games, matching the franchise rookie record (Brockington, 1971; Lacy, 2013) and tying for No. 4 in the league among all players in 2017.
In his first year with the Packers in 2016, Sirmans guided Ty Montgomery in a transition from wide receiver to running back after injuries to Lacy and James Starks. Montgomery started six games at RB and led the team with 457 yards and three TDs on just 77 carries, ranking No. 1 in the NFL (min. 75 att.) with an average of 5.94 yards per carry. Montgomery registered career highs in every rushing category at Chicago in Week 15, racking up 162 yards and two TDs on 16 carries (10.1 avg.), the most rushing yards by a Packer since RB Samkon Gado had 171 yards vs. Detroit in 2005.
Sirmans joined the Packers after spending four seasons (2012-15) with the Rams and establishing himself as a strong developer of young backs. In each of his final three seasons in St. Louis, Sirmans coached a rookie RB who led the team in rushing. In 2015, Sirmans tutored first-round pick Todd Gurley, who led all rookies and finished third among all NFL runners in rushing yards with 1,106 yards (4.8 avg.) to become the first Rams rookie to rush for 1,000-plus yards since Hall of Famers Jerome Bettis (1993) and Eric Dickerson (1983). Named Offensive Rookie of the Year by The Associated Press and earning Pro Bowl honors, Gurley was the first rookie in NFL history to rush for 125-plus yards in four consecutive games (finished with five total), and his 566 yards rushing were the most in a player's first four starts in the Super Bowl era.
Under Sirmans' direction in 2014, third-round selection Tre Mason ran for a team-high 765 yards in 12 games and finished second in rushing yards among all rookies. In 2013, fifth-round pick Zac Stacy started the final 12 games of the season and rushed for 973 yards, the third-highest total by a rookie at that point in team history. In 2012, Sirmans guided veteran Steven Jackson to his eighth consecutive 1,000-yard season as he became just the sixth player in NFL history to rush for 1,000 yards in eight or more seasons.
Sirmans spent five seasons (2007-11) as running backs coach at Boston College, where he mentored the school's No. 3 all-time leading rusher, Montel Harris. In 2011, Harris became the school's career rushing leader and was named the 2011 Atlantic Coast Conference Preseason Player of the Year before a knee injury ended his season prematurely. Harris received first- team All-ACC honors in 2010 after rushing for 1,243 yards on 269 carries (4.6 avg.) and eight TDs. Harris finished his junior campaign 126 yards shy of the all-time school rushing record, and was the active ACC rushing leader with 3,600 yards, the most ever recorded by a junior in the ACC. In 2007, Sirmans helped RB Andre Callender set a BC single-season record for receptions (76), earning him All-ACC second-team honors. Callender led the ACC in yards from scrimmage with 1,709 and set a single-season ACC record for most pass receptions by a running back. The 2007 Eagles began the season 8-0 and ranked No. 2 in the country en route to finishing 11-3, the first BC team to win 11 games since 1940.
Prior to his time at Boston College, Sirmans coached running backs at Michigan State in 2005, where the Spartans finished No. 20 in the nation in rushing (201.8 ypg). In 2006, he coached special teams as well as the running backs. Sirmans spent five seasons (2000-04) coaching at Kent State, where he tutored the running backs. In 2001 and 2002, the team ran for 215.0 yards per game, finishing No. 13 and No. 15 nationally in rushing production those two seasons. In 2004, Kent State scored 30.5 points per game, the second-best mark to that point in school history.
Sirmans began his coaching career at his alma mater, the University of Maine, serving as running backs coach and recruiting coordinator from 1996-1999. As a four-year letterman and starter, Sirmans was a running back under current Iowa head coach Kirk Ferentz for three years (1990- 92). Sirmans ran for 1,214 yards, earning all-conference and All-New England honors his senior year. He graduated from Maine in 1993 with a degree in physical education, health and recreation.
Sirmans was born Oct. 17, 1970, in East Orange, N.J. He is married to the former Letia Thompson. The couple has a son, Marcus, 16.
