Northern Illinois Huskies football coach Thomas Hammock is leaving for the NFL, accepting a position as running backs coach and senior offensive assistant with the Seattle Seahawks, according to ESPN's Pete Thamel.
Hammock is expected to become the league’s highest-paid running backs coach and chose Seattle amid multiple NFL opportunities. The Seahawks are coming off a Super Bowl victory two weeks ago, and Hammock’s addition provides experienced depth to their offensive staff.
A former standout running back at NIU, Hammock compiled a 35-47 record over seven seasons and guided the Huskies to the 2021 Mid-American Conference championship. Northern Illinois posted winning seasons in three of the past five years and earned bowl appearances in 2021, 2023 and 2024.
The signature moment of Hammock’s tenure came in 2024, when NIU stunned 28½-point favorite and No. 5-ranked Notre Dame 16-14 in South Bend, widely regarded as one of the biggest upsets of the college football season.
Defensive coordinator Rob Harley will serve as interim coach, sources said. Maintaining staff continuity and momentum in recruiting and the transfer portal were key factors in the decision.
