The Philadelphia Eagles are primed for another top-seeded season coming into 2026. While the roster looks good on paper, one spot on the sidelines still holds a giant question mark. First-year offensive coordinator Sean Mannion has a lot to prove in the cut-throat City of Brotherly Love.

As Eagles fans raise concerns, Mannion is hard at work on his new offense, figuring out how to optimize the abundance of talent at his disposal. Mannion played quarterback at Oregon State, where he was a four-year starter under head coach Mike Riley. It was Riley who introduced Mannion to the pro-style offense, shaping his entire philosophy as a coach today.

Mannion eventually became a third-round pick in the 2015 NFL Draft, selected by the St. Louis Rams under Jeff Fisher, a proponent of the run-first offensive style. His perspective broadened during a six-year career as a reliable backup, where he studied under some of the brightest minds in the game. He spent time with Sean McVay in Los Angeles (2017–2018) before working with offensive coordinators Kevin Stefanski and Klint Kubiak in Minnesota.

These diverse experiences under established offensive systems prepared him for this high-stakes opportunity in Philadelphia. In Minnesota from 2022 to 2023, Mannion signed as a practice squad quarterback under head coach Kevin O’Connell. In practice, he operated as a player-coach hybrid and an unofficial assistant. Mannion’s role included helping mentor starting quarterback Kirk Cousins on the sideline. By constantly reviewing tablet film and breaking down coverages in real time, he contributed to one of the most productive stretches of Cousins’ career.

Mannion turned to coaching almost immediately after retiring following the 2023 season. He joined the Green Bay Packers as an offensive assistant under head coach Matt LaFleur, and it was there between 2024 and 2025 that he began to build a reputation as a rising offensive mind.

Having coached Mannion in 2017, LaFleur quickly became one of his biggest advocates. In fact, the story goes that LaFleur was so impressed by a presentation Mannion had prepared for an interview with the Chicago Bears that he urged him to skip the interview and head to Green Bay instead.

So as Mannion now prepares for new beginnings in Philadelphia, he carries with him the knowledge of a strong offensive coaching tree, one of which includes Super Bowl-winning offensive coordinator Klint Kubiak. Kubiak runs a West Coast–influenced system that has consistently produced explosive offensive results, including during his time in Seattle.

An example of Kubiak’s impact with the Seahawks was breakout wide receiver Jaxon Smith-Njigba. “JSN” took a massive leap, emerging as one of the league’s most productive receivers and a focal point of the passing game.

Interestingly enough, upon Mannion’s arrival in Philly, reports surfaced that Eagles receiver DeVonta Smith could be in line for a similar breakout in 2026.

Not only does Sean Mannion get to work with a potential star receiver, but also a dynamic quarterback in Jalen Hurts. Hurts offers something Seattle quarterback Sam Darnold didn’t during the Seahawks’ Super Bowl campaign: true rushing ability. In 2023, Hurts set the record for most rushing touchdowns by a quarterback in a single season.

That dual-threat ability gives Mannion a completely different level of flexibility. And it only becomes more dangerous when paired with 2024 2,000-yard rusher Saquon Barkley.

With new pieces like Makai Lemon, who profiles similarly to an Amon-Ra St. Brown-type receiver, and Eli Stowers, a young pass catcher with strong hands and a high motor, this offense has the potential to take a major leap.

If Mannion handles the situation at hand and proves what Matt LaFleur and others have believed about him for years, the Philadelphia Eagles could emerge as a legitimate contender for the Lombardi Trophy at the end of next season.

The future of Philadelphia, and one of the most talented rosters in the NFL, now rests in the hands of first-year offensive coordinator Sean Mannion.

Will he succeed?
