Nick Sirianni: New Eagles OC Sean Mannion has an "obsession to get better" - NBC Sports

What the report says

NBCSports.com’s Pro Football Talk reported that Philadelphia Eagles head coach Nick Sirianni is publicly backing new offensive coordinator Sean Mannion despite Mannion’s limited coaching background and lack of prior play-calling experience. The report, published July 21, 2026, said Sirianni praised Mannion’s work habits during the offseason and described him as deeply committed to improving his craft.

Mannion, 34, was hired after a rapid transition from playing quarterback to coaching. According to the report, he spent nine years in the NFL as a quarterback but started only three games, then worked as an offensive assistant with the Green Bay Packers in 2024 and as their quarterbacks coach in 2025. Pro Football Talk noted that he has not called plays in an NFL game, making him one of the least experienced offensive coordinators hired at that level.

Sirianni said he is not worried about Mannion’s inexperience because of the preparation he has seen, and he pointed to support from other coaches, including Josh Grizzard and Parks Frazier, as well as his own role in helping Mannion prepare. The Eagles have been putting Mannion through situational play-calling exercises, including “pop quiz” scenarios during offseason work, to simulate decisions he will face in games.

The development matters because Philadelphia is entrusting a key role in its offense to a first-time NFL play caller. As NBCSports.com framed it, Sirianni will not have a full answer on Mannion’s readiness until regular-season situations arrive, but six months after the hire, he is presenting confidence in the choice.
