Thomas Hammock is a football coach who just made a decision that surprised a lot of people in the sport. He walked away from being the head coach at Northern Illinois University—a Division I program where he’d spent seven years—to become the running backs coach for the Seattle Seahawks. Not a promotion in title, but reportedly the highest-paid running backs coach contract in NFL history.
He was born on July 7, 1981, in Jersey City, New Jersey, which makes him 44 years old as he enters his new role in Seattle. His journey from player to position coach to head coach and back to the NFL reads like someone who understands what he wants and isn’t afraid to make unconventional moves to get there.
Early Yers and Finding Football
Thomas Hammock grew up in Jersey City before his family moved to Fort Wayne, Indiana, where he attended Bishop Luers High School. Fort Wayne isn’t a major recruiting hotbed, but Hammock was good enough to earn a scholarship to Northern Illinois University, where he played running back from 1999 to 2002.
As a player at NIU, he rushed for 2,432 yards in 32 games under head coach Joe Novak, which ranks 13th all-time at NIU. Those numbers show he was productive, but not extraordinary. What mattered more than the yards was what he learned about the game during those years—lessons that would shape the coach he’d become.
He earned his bachelor’s degree in marketing from NIU in 2002, and a master’s in educational leadership from the University of Wisconsin–Madison in 2004. That master’s degree tells you something about his mindset early on. He wasn’t chasing football glory alone. He was preparing for a career beyond playing.
Wife and Family Life
He and his wife, Cheynnitha, also a NIU alum, have a daughter, Tierra, and a son, Thomas Douglas.
Cheynnitha attended Northern Illinois, which is where they met. The couple has kept most of their family life private, preferring to keep attention on his coaching work rather than personal details. Their daughter Tierra and son Thomas Douglas have grown up watching their father’s coaching career unfold, from position coach to head coach and now back to the NFL.
The decision to move his family back to the Pacific Northwest for this opportunity required agreement from everyone involved. Uprooting a family from Illinois to Seattle isn’t a small choice, particularly when it meant leaving a head coaching position for an assistant role.

Building a Coaching Career From the Ground Up
Hammock’s coaching career started at Wisconsin, where he worked as a graduate assistant from 2003 to 2004 while completing his master’s degree. He then returned to Northern Illinois as the running backs coach in 2005, reuniting with Joe Novak, the same coach he’d played for.
His first season coaching NIU’s running backs produced immediate results. Garrett Wolfe rushed for 1,580 yards and 16 touchdowns in just nine games, helping NIU win the MAC West Division and reach the MAC Championship Game for the first time in school history.
He moved to Minnesota in 2007, where he spent four seasons—first as running backs coach, then as co-offensive coordinator in his final year under Jerry Kill. In 2011, he joined Wisconsin’s staff under Bret Bielema, coaching elite running backs like Montee Ball, James White, and Melvin Gordon.
That Wisconsin experience opened doors. On February 5, 2014, the Baltimore Ravens hired him as their running backs coach, his first NFL position. He spent five seasons in Baltimore from 2014 to 2018, where he worked alongside current Seahawks head coach Mike Macdonald, who was on the Ravens’ defensive staff during that time.
Seven Years Leading Northern Illinois
On January 18, 2019, Hammock was named the 23rd head football coach at his alma mater, Northern Illinois. Coming home to lead the program where he’d played was meaningful to him personally, though the results weren’t always what he hoped for.
His first season saw NIU go 5-7 overall. His second season in 2020 was disrupted by COVID-19, and the team went winless in six MAC games with a roster that was 71% freshmen. Those early years were difficult, but he kept building.
The breakthrough came in 2021. Northern Illinois was predicted to finish last in the MAC West Division. Instead, led by transfer quarterback Rocky Lombardi, they upset Georgia Tech in week one and went on to win the conference championship. Hammock was named 2021 MAC Football Coach of the Year. On November 9, 2021, Hammock signed a contract extension through the 2026 season.
The program’s crowning moment came on September 7, 2024, when his Huskies traveled to South Bend and stunned No. 5 Notre Dame. NIU defeated the fifth-ranked Notre Dame Fighting Irish at Notre Dame Stadium, earning NIU its first-ever win over a top-10 opponent, and becoming the first MAC team to ever beat a top-5 opponent.
Despite that historic win, the 2024 season ended poorly. NIU finished 3-9 and 11th in the MAC. Hammock’s overall record as head coach was 35-47 with three bowl appearances. The program had regressed, and questions about his future were already circulating before the Seahawks came calling.

The Seattle Opportunity
According to ESPN’s Pete Thamel, Hammock interviewed for the Seahawks’ offensive coordinator position; Seattle chose San Francisco tight ends coach and run game coordinator Brian Fleury for that job.
He didn’t get the coordinator job, but Seattle wasn’t done with him. He chose to join on in Seattle anyway as the running backs coach due to the lucrative offer proposed by his former colleague in Seahawks head coach Mike Macdonald, who served on staff with Hammock in Baltimore under Harbaugh.
Hammock is expected to become the highest paid running backs coach in the NFL, and chose the Seahawks over “multiple” NFL opportunities. That detail matters. He wasn’t desperate for any NFL job. He had options and chose Seattle specifically because of the compensation, the relationship with Macdonald, and the opportunity to work with starting running back Kenneth Walker III.
The official announcement was confirmed by multiple sources including espn.com and si.com.
Why Leave a Head Coaching Job?
It’s unusual for a Division I head coach to leave for an assistant role in the NFL, even with the highest salary at that position. But Hammock’s decision makes sense when you understand what he values.
“I enjoyed my college experience,” Hammock said. “I didn’t get one dime. But the lessons I learned were more valuable than any money you could ever pay me. I appreciate that because that’s long term. People are losing the fact this is short term… Don’t lose focus of the long term. Get your degree and learn valuable lessons that are going to help you in the long term of your life.”
That quote reveals his philosophy about college football in the NIL era, but it also reveals something about him personally. He values long-term thinking over short-term titles. Being a head coach at Northern Illinois with a 35-47 record and dwindling resources wasn’t the long-term play. Being the NFL’s highest-paid running backs coach on an ambitious NFL staff led by head coach Mike Macdonald, reuniting with a head coach he trusts, absolutely is.
What He Brings to Seattle
In his final season at Baltimore, Hammock helped the Ravens become the second-ranked rushing offense. Most of his schemes and philosophies with Baltimore utilized multiple running back schemes.
His track record at Wisconsin with Ball, White, and Gordon shows he can develop elite talent. His Baltimore experience shows he can succeed in the NFL. His head coaching experience at NIU gives him leadership perspective that most position coaches don’t have.
Seattle’s backfield situation is uncertain. Kenneth Walker III, the Super Bowl MVP, is a free agent. Zach Charbonnet tore his ACL in the playoffs. The Seahawks will need to rebuild that position group, and Hammock will be central to that process.
Net Worth and Financial Reality
Hammock’s exact net worth has not been publicly disclosed, but estimates based on his coaching salary history suggest a range between $3 million and $6 million. His NIU contract after the 2021 extension was substantial for a MAC head coach, though specific figures weren’t published.
His new Seattle contract makes him the reportedly among the highest-paid running backs coaches in the NFL. While exact salary figures haven’t been released, top NFL assistant coaches earn between $1.5 million and $3 million annually. Given the “highest-paid” designation, his salary likely exceeds $2.5 million per year.
For context, Hammock earned significantly less as NIU’s head coach than he’ll make in Seattle, despite the title difference. That financial reality influenced his decision alongside the professional opportunity.
