The New York Giants are keeping coach Charlie Bullen on the team under new head coach John Harbaugh. Bullen will now also be in charge of the team's run game. This move comes after Bullen showed skill in improving the Giants' defense against runs during the past season. The team hopes his knowledge will help them stop opposing teams from running the ball effectively.

Coaching Staff Changes Under New Leadership
When John Harbaugh took over as head coach for the New York Giants, many coaching staff members were let go. Reports from January 2026 indicate that most defensive coaches from the previous staff were dismissed. Amidst these changes, Charlie Bullen was seen as one of the few defensive coaches who might stay.

Previous Staff Departures: Several coaches, including Andre Patterson, John Egorugwu, Marquand Manuel, and Jeff Burris, were told they would not be retained by the new head coach.
Bullen's Potential Retention: Early reports suggested Bullen was the only defensive coach with a chance to remain on Harbaugh's staff.
Harbaugh's Sought-After Coaches: There was speculation that Jim Leonhard could be a candidate for defensive coordinator, and Todd Monken was considered a favorite for offensive coordinator, given his past work with Harbaugh.
Bullen's Rise to Interim Defensive Coordinator
In November 2025, Charlie Bullen was appointed interim defensive coordinator. This decision came after the Giants had a difficult time protecting leads, especially in the late stages of games. Interim head coach Mike Kafka made this change after the team's sixth consecutive loss.

Kafka's Decision: Kafka stated he had faith in the previous defensive coordinator, Shane Bowen, but felt a change was necessary due to the defense's inability to hold onto leads.
A Curious Choice: Bullen, who had 18 years of coaching experience but no prior experience as a defensive coordinator, was chosen over coaches like Marquand Manuel and Andre Patterson, who had experience at that level.
Bullen's Impact: Despite being new to the defensive coordinator role, Bullen is credited with helping to revitalize the team's struggling defense. He was given five games to prove his abilities.
Defensive Performance Under Bullen
The Giants' defense was one of the worst in the league, allowing an average of nearly 28 points per game, which led to Shane Bowen's dismissal. Charlie Bullen took over with the goal of making needed improvements.

Positional Coach Success: Even before becoming interim defensive coordinator, Bullen made a positive impression as the outside linebackers coach.
Player Success: Players like Brian Burns, who had a career-high number of sacks, credited Bullen's close work with them for their improved performance.
Bullen's Future and New Role
Despite interest from other teams, such as a reported interview request from the Dallas Cowboys in January 2026, Charlie Bullen has opted to stay with the Giants. His new role as run-game coordinator signifies the confidence the new coaching staff has in his abilities, particularly his understanding of stopping the run, an area where the Giants had previously struggled but saw improvement under Bullen's influence.
Bullen’s extended contract and new title suggest a significant belief in his coaching capabilities from the Giants’ new leadership.
His past work revitalizing the run defense under difficult circumstances appears to have been a key factor in his retention.
Expert Analysis
"Mike Kafka’s choice to serve as interim defensive coordinator is outside linebackers coach Charlie Bullen, an 18-year coaching veteran (12 in the NFL) who has never been a defensive coordinator before, a curious pick over defensive backs coach Marquand Manuel and defensive line coach Andre Patterson, both of whom have NFL defensive coordinator experience." - Source: Article 4

Conclusion
Charlie Bullen's continued employment with the New York Giants, now holding the title of run-game coordinator and an extended contract, highlights his growing value. His appointment as interim defensive coordinator in late 2025, despite a lack of prior experience in that specific role, and his subsequent success in improving the team's defensive performance against the run, have evidently earned him the trust of the new coaching regime led by John Harbaugh. While other teams expressed interest, Bullen's decision to remain with the Giants points to a stable opportunity and a belief in the direction of the franchise.
