The Sean Mannion Offense: Part 1: Basic Principles

The Sean Mannion Offense: Part 1: Basic Principles

Full disclaimer: I have no idea what the Philadelphia Eagles’ offense will look like in 2026. New offensive coordinator Sean Mannion has never called plays over a full NFL season. New pass game coordinator Josh Grizzard has only done it once. There is no finished product to evaluate yet, no Eagles film to diagnose, no certainty to lean on. However, we can formulate some ideas based on past evidence. There is Mannion’s background inside the McVay–LaFleur–Shanahan ecosystem. There is his one public play-calling sample at the Shrine Bowl, where he installed an offense under time constraints. There are also years of league-wide data on how this coaching tree builds offenses.

The goal of this short series is not to guess which plays the Eagles will call, but to understand how this staff is likely to think about offense and what we might see from the Eagles next year. With free agency and the NFL Draft just around the corner, I figured it’s a good time to get into it, as there may be some key takeaways regarding the type of player the Eagles may target.

Part 1: Basic Principles

For the last few years, the Eagles’ offense has lived on “hero ball.” When things broke down, Jalen Hurts used his legs or made a wild throw to save the day. Saquon Barkley would make a defender miss and take it to the house. A.J. Brown would win a one-on-one vertical shot and score a touchdown. It’s exciting when it works, but it’s a hard way to live, especially when these players have an off game. When you rely on improvisation, rhythm can disappear quickly, easy throws get missed, and suddenly every third down feels like a life-or-death situation.

Hiring Sean Mannion is a sign that the Eagles are moving in the opposite direction. It’s more about the scheme rather than just about having the best players. Mannion is a fast riser who spent the last two seasons in Green Bay, specifically helping Jordan Love and Malik Willis master a system built on timing and design. He comes from the Matt LaFleur and Sean McVay tree, where the goal isn’t for the quarterback to save the system, but for the system to make everything easier on the quarterback.

The core philosophy is about “clarity.” You want an offense that looks complicated to the defense, by using motion and heavy formations to disguise intent, but feels simple and calm for the guy under center because he already has the answers. I went back and watched 5 full Green Bay games from last year, and a few things kept standing out.

Against Pittsburgh, the Packers align under center, with the tight end serving as a fullback-like presence in the backfield. The play-action fake holds the second level just long enough to hollow out the intermediate middle of the field, and the throw that follows is routine by design. Hurts is going to have to get used to hitting his back foot and hitting this shot. The Packers do not throw these middle-of-the-field throws anywhere near enough as the Rams and Packers do, so I think some of the worry about Hurts translating is overblown. Trust me, they don’t run this stuff as much as you expect. This is not the Rams and Matthew Stafford. However, Hurts will have to get used to hitting his back foot and getting the ball out. We’ll cover play-action in a separate article, but it’s a big deal in this offense!
