John Harbaugh was hired as the 24th coach in the New York Giants team history on January 20th. He has spent the better part of the last several weeks finalizing the coaching staff for the 2026 season, and finalized it as of February 13th. Here’s an introduction to the new offensive staff and the 3 members who will define the 2026 season.
Matt Nagy (Offensive Coordinator)
- 2023-25: Kansas City Chiefs – Offensive Coordinator
- 2022: Kansas City Chiefs – Sr. Off. Asst./QBs
- 2018-21: Chicago Bears – Head Coach
- 2017: Kansas City Chiefs – Offensive Coordinator
- 2016: Kansas City Chiefs – Co-Offensive Coordinator
- 2013-15: Kansas City Chiefs – Quarterbacks
- 2011-12: Philadelphia Eagles – Offensive Quality Control
- 2010: Philadelphia Eagles – Assistant Coach
- 2008-09: Palmyra Area High School – Offensive Coordinator
- 2001: Manheim Central High School – Assistant Coach
Matt Nagy got his start under Andy Reid in Philadelphia in 2008, as an intern before eventually rising to assistant coach in 2010. He developed a fantastic relationship with Reid, and when Reid was eventually hired by the Kansas City Chiefs, Nagy followed and was on staff for two years before quickly earning the role of Chicago Bears head coach.
Nagy was extremely successful in year 1, leading the Bears to a 12-4 record and subsequent playoff birth. He had two 8-8 seasons right after, and ended up back with Reid again, in Kansas City. In 2022, now working with Patrick Mahomes as opposed to Mitch Trubisky, he helped the Chiefs average a league-leading 29.1 points per game and win the Super Bowl over the Eagles. Nagy was the OC for three more seasons, which resulted in a Super Bowl appearance, a Super Bowl loss, and a 6-11 record this season.
Greg Roman (Senior Offensive Assistant)
- 2024-25: Los Angeles Chargers – Offensive Coordinator
- 2019-22: Baltimore Ravens – Offensive Coordinator
- 2017-18: Baltimore Ravens – Assistant Head Coach/Tight Ends
- 2015-16: Buffalo Bills – Offensive Coordinator
- 2011-14: San Francisco 49ers – Offensive Coordinator
- 2009-10: Stanford – Associate Head Coach
- 2008: Holy Spirit High School – Offensive Coordinator
- 2006-07: Baltimore Ravens – Offensive Line Assistant
- 2004-05: Houston Texans – Quarterbacks
- 2002-03: Houston Texans – Tight Ends
- 1995-2001: Carolina Panthers – Offensive Line Assistant
Greg Roman has over 20 years of NFL experience across 6 NFL franchises. He spearheaded the option offense movement of the early 2010’s and was instrumental in getting the San Fransico 49ers to three straight conference championships and one Super Bowl, from 2011 to 2014. Few remember his 2015 stint as the Buffalo Bills OC, he led them to the 12th most PPG with both Tyrod Taylor and EJ Manuel earning starts.
He took a year off before joining Baltimore in 2017 and was instrumental in the development of Lamar Jackson, helping shape him into a two-time MVP winner. He followed this stint up with a stint in LA and helped Justin Herbert garner MVP votes this season as well. His tutelage will be crucial in developing Jaxson Dart from prospect into a franchise cornerstone.
Brian Callahan (Passing game coordinator and QB coach)
- 2024-25: Tennessee Titans – Head Coach
- 2019-23: Cincinnati Bengals – Offensive Coordinator
- 2018: Oakland Raiders – Quarterbacks Coach
- 2016-17: Detroit Lions – Quarterbacks Coach
- 2015: Denver Broncos – Offensive Assistant/Quarterbacks Coach
- 2013-14: Denver Broncos – Offensive Assistant
- 2011-12: Denver Broncos – Offensive Quality Control
- 2010: Denver Broncos – Coaching Assistant
- 2008-09: Junipero Serra High School – Offensive Coordinator/Quarterbacks Coach
- 2006-07: UCLA – Graduate Assistant
Brian Callahan is the most maligned coach brought in for year 1 of the Harbaugh experience. The former Tennessee Titans head coach led offenses that finished 30th in EPA per play and 29th and 31st in success rate. Was this due to subpar quarterback play by the inexperienced Cam Ward and Will Levis, or did Callahan struggle to give his teams a schematic advantage?
We have to evaluate the Cincinnati Bengals offense before and after his departure. In 2022 and 2023, the Bengals offense ranked 4th and 12th in EPA per play, with Joe Burrow missing seven full games in 2023. After his departure, they ranked 7th in 2024 and 19th in 2025, with Burrow missing substantial time in 2025. Callahan spearheading an above-average offense in 2023 without Burrow was extremely impressive, and hopefully, with a reduced role as passing game coordinator, he will be able to return to form.
