John Harbaugh will retain two — and only two — coaches from Brian Daboll’s stable of assistants, adding outside linebackers coach Charlie Bullen and tight ends coach Tim Kelly to his first Giants staff, The Post has learned. 

There is nothing remotely unusual about this. New head coaches routinely purge the building of the coaches from the previous regime, preferring to build their staff with their own hires, either with those they previously worked or hand-picked newcomers. 

This means Harbaugh will bring in his own offensive line coach and the popular Carmen Bricillo will not be back. 

Bricillo and his assistant, James Ferentz, helped the Giants put on the field their best offensive line play in years and the bulk of that line — left tackle Andrew Thomas, left guard Jon Runyan Jr. and center John Michael Schmitz — is under contract and expected to return to the starting lineup. The Giants offensive line was ranked ninth-best in the NFL, according to Pro Football Focus, led by the two starting tackles.

Thomas allowed pressure on 3.1 percent of pass plays, the second-best rate among all offensive tackles. Jermaine Eluemunor, set to become a free agent, allowed pressure on 3.3 percent of pass plays, lowest among all right tackles.

As a unit, PFF graded the Giants No. 4 in the league in pass-blocking efficiency. That unit was 30th in 2024. The line, though, will move forward with new position coaches. 

Harbaugh could turn to George Warhop, who spent the past two seasons in Baltimore. The Ravens offensive line regressed in 2025, grading out by PFF as the No. 16 unit in the league. Warhop, 64, has been an NFL offensive line coach since 1996 for nine different teams.

Bullen, 41, commanded a room filled with talent: Brian Burns, Kayvon Thibodeaux and rookie Abdul Carter. Burns finished with a career-high 16.5 sacks, Thibodeaux endured an injury-shortened season and Carter, the No. 3 pick in the 2025 NFL Draft, is a finalist for the Defensive Rookie of the Year award.

Bullen was promoted to interim defensive coordinator after the Week 12 overtime loss in Detroit, as interim head coach Mike Kafka fired Shane Bowen. Under Bullen’s direction, the defense became more aggressive and Carter’s production increased dramatically. With Bullen making the defensive calls for the final five games, the Giants improved their run defense (157.2 yards a game to 110.3), sacks per attempt (6.1 percent to 12.6 percent) and points per game (27.8 points to 22.0). 

Bullen was a defensive assistant in Miami for five seasons (2012-16). That corresponded with Giants general manager Joe Schoen’s tenure in scouting for the Dolphins.

Kelly, 39, arrived in 2024 and Kafka promoted him to interim offensive coordinator after Daboll was fired 10 games into the season. He had previously been an offensive coordinator for the Texans and Titans. Retaining Kelly will provide continuity for Theo Johnson as he enters his third NFL season. 

For Harbaugh’s defensive coordinator, Anthony Weaver (Dolphins), Dennard Wilson (Titans) and Jim Leonhard (Broncos) are strong options. Weaver is in play for head coach openings this cycle, though. Todd Monken, on Harbaugh’s staff in Baltimore the past three years, is the favorite to be hired as the offensive coordinator.
