Branch 1: The Head Coaches (The Sirianni/Eagles Coordinator Sprout)
The most defining characteristic of the Sirianni coaching tree is the immediate success of his top coordinators in securing Head Coach positions. The 2023 offseason saw two coordinators depart for new opportunities, and the 2025 cycle added a third, showcasing the high regard NFL owners have for Sirianni's staff.
Shane Steichen: Indianapolis Colts Head Coach
Shane Steichen was Sirianni's first Offensive Coordinator in Philadelphia (2021–2022) and was instrumental in the development of quarterback Jalen Hurts. Steichen’s knack for designing a dynamic, run-heavy attack combined with timely deep passing led the Eagles to a Super Bowl appearance.
Current Role: Head Coach, Indianapolis Colts (2023–Present). His move to the Colts was a natural fit, as both he and Sirianni share roots with Frank Reich’s coaching philosophy.
Jonathan Gannon: Arizona Cardinals Head Coach
Jonathan Gannon served as the Eagles’ Defensive Coordinator (2021–2022) and was hired by the Arizona Cardinals in 2023. Gannon’s career path is deeply intertwined with Sirianni, as he was the defensive backs coach for the Colts while Sirianni was the offensive coordinator there. Sirianni brought Gannon to Philadelphia, trusting him to lead the defense.
Current Role: Head Coach, Arizona Cardinals (2023–Present). His defensive schemes were often scrutinized but ultimately proved effective enough to help the Eagles reach the Super Bowl LVII.
Kellen Moore: New Orleans Saints Head Coach
The biggest and most recent development in the Sirianni tree is the hiring of Kellen Moore as the Head Coach of the New Orleans Saints for the 2025 season. While Moore was only the Eagles' Offensive Coordinator for the 2024 season, the opportunity to call plays under Sirianni's 'CEO' style of head coaching was clearly a successful springboard. This rapid promotion after just one year highlights the prestige associated with the Eagles' top coordinator position under Sirianni.
Branch 2: The Next Generation of Sirianni Proteges (2025 Staff Elevates)
With three Head Coach departures, Sirianni has consistently had to promote from within and recruit new talent, leading to the rise of several other key figures who are now positioned for future coordinator and head coaching roles. The 2025 staff changes, in particular, signal who Sirianni trusts to maintain the team's high level of performance.
Kevin Patullo: Philadelphia Eagles Offensive Coordinator
Kevin Patullo is a long-time, trusted confidant of Nick Sirianni and the new Offensive Coordinator for the Eagles, a promotion that came in the wake of Kellen Moore's departure. Patullo and Sirianni worked together with the Indianapolis Colts from 2018–2020. He initially joined the Eagles in 2021 as the Passing Game Coordinator, a role he excelled in before being elevated to Associate Head Coach/Passing Game Coordinator in 2023.
Current Role: Offensive Coordinator, Philadelphia Eagles (2025–Present). Patullo is expected to take over play-calling duties, making him the next likely candidate to earn a Head Coach interview.
Parks Frazier: Philadelphia Eagles Passing Game Coordinator
Parks Frazier is another coach with deep ties to Sirianni from their time with the Indianapolis Colts. Frazier began his NFL coaching career in Indianapolis in 2018, assisting Sirianni, who was the Colts' offensive coordinator. He briefly served as the Colts' interim play-caller in 2022, demonstrating his readiness for larger responsibilities. Sirianni brought him to the Eagles' staff in 2024.
Current Role: Passing Game Coordinator, Philadelphia Eagles (2024–Present). His role is critical in integrating new offensive concepts and preparing the passing attack, positioning him as a rising star within the organization.
The Sirianni Coaching Philosophy and Topical Authority
The rapid expansion of the Nick Sirianni coaching tree is not accidental; it stems from a distinct and transferrable coaching ideology. This philosophy is centered on clear communication, emotional intelligence, and a focus on player-coach "connection."
- Connection Over Command: Sirianni emphasizes building deep personal relationships with players and staff, believing that better connection leads to better performance and stronger coaching chemistry. This is a core reason why his coordinators are highly valued.
- The CEO Model: Sirianni has transitioned to a 'CEO' style of head coaching, focusing on organizational culture, game management, and delegating play-calling and scheme design to his coordinators. This delegation empowers his assistants, giving them the autonomy and experience necessary to run their own teams.
- Adaptability: The tree has shown a remarkable ability to adapt. Steichen led a run-first offense with Jalen Hurts, while Moore was brought in to modernize the passing attack—both found success, proving that Sirianni’s system is about finding the right people, not just the right plays.
Other notable entities and rising coaches who contribute to the topical authority of the Sirianni Tree include:
- Jeff Stoutland: Offensive Line/Run Game Coordinator. A veteran coach retained by Sirianni, whose consistent excellence is a bedrock of the Eagles' success.
- Jemal Singleton: Assistant Head Coach/Running Backs Coach. Another key figure from the original Sirianni staff, providing continuity and leadership.
- Alex Scudder: Promoted from Coaches Assistant to a higher-level role, Scudder represents the next wave of internal promotions within the Eagles organization.
The Nick Sirianni coaching tree, planted just a few seasons ago, is already producing some of the NFL’s most sought-after Head Coaches. With Shane Steichen and Jonathan Gannon establishing their teams and Kellen Moore joining the ranks in 2025, the influence of Sirianni’s tenure in Philadelphia is proving to be one of the most significant coaching dynasties of the decade. The next few years will see if Patullo and Frazier can follow in their predecessors' footsteps, further solidifying the Eagles' reputation as a premier breeding ground for NFL leadership.
