Is Sean Mannion ready for his big moment with the Eagles? He’s been preparing for it for years.
Mannion learned at the feet of his father, John, before stops at Oregon State and as an NFL journeyman QB helped shape his apprenticeship.
Mike Riley and Sean Mannion were having one of their catch-up calls when Mannion, who played quarterback at Oregon State under Riley, told his former coach the latest project he was working on during the nascent days of his own coaching career.
Mannion, the most prolific passer in Oregon State history, told Riley that he was putting together and digitizing all of the passing concepts he could find dating back to the 1960s.
“This is what he does in his spare time,” Riley explained recently.
Mannion is just 34 years old and only three years removed from his playing career. He has never called plays in the NFL before and now is tasked with turning around an Eagles offense that was too stagnant in 2025 under another first-year coordinator and first-time play caller Kevin Patullo. Nick Sirianni said in February that he was looking for someone who was detailed and had “conviction in what they believed and why they believed in it, and the vision and conviction of how they went about it.”
Those traits seem to describe Mannion, whose father, John, called him “a saver” who took and saved detailed notes at every stop along his football path and even has comprehensive notes on concepts that pre-date his own life by some 30 years. Eagles quarterbacks coach Parks Frazier raved recently about Mannion’s attention to detail and his ability to recall and reference something he has learned along the way.
“He remembers every detail about all of those things and he’s constantly applying it to what he’s doing moving forward,” Frazier said. “He has extreme, detailed, categorized notes and film of everything he’s been through.”
Mannion is installing a new offense for Jalen Hurts and the Eagles, one rooted in the flavors of the trendy Kyle Shanahan-Sean McVay scheme. But Mannion’s history and influences suggest a style that ultimately will pull from every resource imaginable as he guides the Eagles offense into the future.
Sirianni and Howie Roseman took a calculated risk on a young and fast-rising offensive coach when they landed on Mannion, who spent two years on the staff in Green Bay, most recently as quarterbacks coach, before his big promotion. But a lack of experience doesn’t necessarily mean Mannion is any less equipped to succeed than a more experienced candidate. In many ways, Mannion, the son and grandson of football coaches, has been preparing for this job for most of his life.
“His thing was, he wanted to play as long as he could,” his father said. “The unsaid part was that when those days were done that he would turn his attention to coaching.”
Like father, like son
At its roots, coaching is teaching. In that sense, Sean isn’t just the son of a football coach; he is the son of two teachers, and his earliest influences can be traced to the classroom. He’d mess around in a playpen while his mother, Inga, an elementary school teacher, finished work in her classroom after school.
He was around his father’s football teams as much as he could be, too. One Saturday, John, who also has been a teacher for 36 years, was going to scout an upcoming opponent with a coaching friend and Sean wanted to tag along. He was around 7 years old and an inquisitive kid at the time, so he brought with him a yellow legal pad. While he watched the game next to the two adults, he doodled and drew notes and observations from the field.
“He spent a lot of time doing what we were doing,” John said of his son’s early days. “That notepad probably was a byproduct of all that time spent.”
Sean grew up in Pleasanton, Calif., Alameda County, about 20 miles east of the San Francisco Bay in a household that valued education. He was a good student who also excelled in sports. Football was his main sport, but he also played baseball and basketball.
When Sean was a rising sophomore at Foothill High School, John, a former assistant, was given the job as the school’s head football coach. He was nervous, though, about any appearance of nepotism, so from the outset of that season he had Sean playing on the JV team. Foothill was 12-1 the previous season and had two upperclassmen ahead of Sean on the depth chart. A week before the season, the senior quarterback hurt his ankle and was on crutches. Later that week, after throwing at least four touchdowns in a scrimmage, the junior quarterback showed up on Labor Day, the first practice of the first game week of the season, and complained about a back injury that eventually forced him to miss the season.
John called home right away. Sean had to get to the field and get to practice.
Sean’s freshman coach at Foothill was Mike Madden, the son of Hall of Fame coach John Madden. Mike approached John Mannion/ that first week and asked him if he was nervous for Sean.
“Gosh, I hadn’t thought about it,” John said. “I’m nervous for myself at this point.”
John’s first game as varsity head coach was also Sean’s first game as varsity starting quarterback. Asked if he remembered it well, John responded the way many coaches would, and the way the father of a detailed note-taker would: “Oh yeah,” he said. “Of course I do, yeah. We lost, 26-21, and Sean did really well. It was a really hot day and there was a lot learned by me.”
The team they lost to went to the state playoffs, but so did Foothill. Sean “knew the offense from all those years growing up around it” and “really absorbed a lot of things along the way,” John said.
“We kind of went through it together,” John said. “There was no plan of him ever being on the team that first year, but sure enough there he was. There’s challenges in there but I think it was a great experience for us to be able to do that.”
Sean finished his high school career as Foothill’s all-time leading passer and, after throwing for 3,521 yards and 27 touchdowns as a senior, was off to Oregon State.
That yellow legal pad Sean doodled on during that football scouting trip was part of a full-circle moment some 25 years later.
“When I got my first coaching job with the Packers, as a gift, he framed it for me,” Sean said. “So I still have it in my house. It’s pretty cool. The scheme has evolved since then, I will say, but it was a really cool, special gift that he kept.”

The Machine
Riley’s favorite word to describe Sean is “diligent.” How many coaches born in the 1990s are digitizing passing concepts from the 60s?
Sean was the top quarterback Oregon State pursued in the class of 2010, and Riley and his staff were thrilled when he committed and later signed. The program had produced top quarterbacks like Derek Anderson and Matt Moore, and Riley thought Sean would be the next great one to come through Corvallis.
The diligence showed up right away. Sean was supposed to redshirt during his first season on campus, but the summer before his first camp with the Beavers, Sean got the keys to the facility from the graduate assistants to go in early and watch film.
“That was him the whole time,” Riley said. “He could really throw the football and he was a very hard worker physically, and then he was a very hard worker off the field. He wanted to know and learn and he’s one of the most diligent people that I’ve ever been around.”
That part of Sean made it easier when, during the second half of the first game the following season, Riley put Sean in the game over a junior who started. He was just a redshirt freshman, but he was Oregon State’s starter from that point until graduation.
“That was one of the first times probably in my career that I actually had the faith in a redshirt freshman to insert him sometime early in the year as a starter,” Riley said. “I think that said a lot about what we felt about his early development and what we thought he could do on the field.”
Sean became a captain the following season. He is soft-spoken by nature, those closest to him say, but his leadership showed up in the way he carried himself and how he approached the game. By senior year, he had a nickname: “The Machine.” That year’s offensive coordinator, John Garrett, referred to Sean by that moniker during a film session one day and it stuck, much to Sean’s chagrin. Oregon State’s offensive linemen sometimes walked robotically around Sean.
“That is a pretty appropriate nickname because he was just like that,” Riley said. “He just went to work and put in the work and everybody knew that about him. I think he’s one of the most probably respected teammates that I saw through all my years of coaching.”
Sean exited college as Oregon State’s all-time leader in passing yards and ranked in the top 10 in college football history. He’s still 19th.
The quarterback and coach have stayed in touch over the years. Riley, who left Oregon State for Nebraska after Sean’s senior year, is now retired, though he’s still on the College Football Playoff selection committee. Sean isn’t the most recent Mannion whom Riley had talked to as of a few weeks ago, though. John, who no longer coaches, now writes a newsletter on Substack called “John Mannion’s Coaching Playbook,” and recently interviewed Riley.
Sean’s most recent catch-up call with his college coach came after OTAs this season and just before camp.
“He sounded excited and he sounded like he would be because he’s always prepared — he sounded confident,” Riley said. “And I could also tell he was having a lot of fun.”
‘A 30,000-foot view’
Sean has described his father and Riley as his two biggest influences along the way. But his most relevant football influences when it comes to his current job came into his life in 2017, when Sean was backing up Jared Goff with the Los Angeles Rams and the team brought in a new coach, McVay, who hired a new offensive coordinator, Matt LaFleur. Both had been schooled under Shanahan and brought to the Rams a new style of offense that Sean took to.
“I just felt like I was learning so, so much,” Sean said. “It was such an exciting way to match the run and pass. They had such a way about teaching the game where we could feel ourselves challenging a defense, but it felt simple to us.
“Those are the things that really stood out to me going through that experience that really resonated with me as a player and certainly resonate with me as a coach. That was a very exciting point in my football life, just the exposure to that type of teaching, that type of scheme. I know Matt, obviously a mentor of mine, getting to play for [McVay]. I learned so much from those people. It’s certainly a big part of molding me into the type of coach I am now.”
How the Eagles offense will look come Sunday still remains a sort of mystery. There certainly will be more motion, more snaps from under center, and more play-action. But the Eagles ran a bland offense during the preseason in an effort to hide most of their playbook, and the first-team offense was rarely fully healthy during training camp and also had to go against one of the best defenses in the league.
The Eagles have a new style of running the ball, which will be a key to unlocking the passing game and play-action. The base of the Shanahan-McVay offense is outside, wide-zone runs that stretch the defense horizontally. The Eagles and longtime offensive line coach Jeff Stoutland parted ways this offseason, and new offensive line coach Chris Kuper has been in charge of implementing the new blocking scheme.
Kuper was the offensive line coach in Minnesota when Sean spent part of the 2023 season with the Vikings.
“He sees the game from a 30,000-foot view as well as being on the sideline and being into it with the players,” Kuper said. “I think it speaks volumes, his experience as a quarterback in this league and being able to connect people and become a glue guy has been incredible.”
There may be a misconception that Sean, a quarterback by trade, just focuses on the quarterbacking. But Kuper described a coach who is involved in every facet of the offense.
“What I love about Sean is how much he loves the run game,” Kuper said.
Kuper said part of Sean’s responsibilities in Green Bay when he was an offensive assistant in 2024 was to draw some runs. The Eagles do have a run-game coordinator in tight ends coach Ryan Mahaffey, but Kuper is confident Sean could handle it all.
“Sean could game plan and call a game all on his own, I think, if he wanted to,” Kuper said.
First-time play caller
The Mannions relocated to Oregon when Sean was in college, and one spring after John had taken over as the head coach at Mountainside High, he needed help.
The 2021 football season came together rather late in the midst of the COVID-19 pandemic, and a shortened spring season was on the table. Sean was home in Oregon doing remote OTAs with the Vikings when John asked him to be the offensive coordinator that season.
Sean’s younger brother, Brian, was the starting quarterback. It was a family affair.
On the day of the first practice, John walked out on the field and handed Sean his handwritten practice plan.
“You know there’s software for this, right?” Sean quipped.
John was calling plays, but after Mountainside was shut out in the second of their six games, John made a change.
“I handed the torch to him. It was fun,” John said.
John has watched the oldest of his four children become a loving husband to his wife, Megan, and the proud father of three children. He always knew Sean could and probably would eventually become a successful coach, but that spring offered his first real chance to witness Sean’s future in person.
“I could see clearly he had a real knack for it,” John said.
Sean was still in the process of talking to the Eagles when he was tapped to call plays in January’s East-West Shrine Bowl. He called John during his father’s lunch break.
“You haven’t called a game since Mountainside vs. Grant High School back in March of 2021,” John joked.
The two shared a laugh. A few days later, Sean was hired to call plays for the Eagles.
All roads lead to Delco
Margaret Mannion was around 20 years old when she moved to California, but John’s mother spent her early days in Delaware County. She lived in Drexel Hill, graduated from Archbishop Prendergast High School, and worked at Villanova before moving west, where she met Jim Mannion, John’s late father.
Margaret, 84, has dementia now and still lives in California in an elder care facility, but John is pretty confident there will be at least one “proud Philadelphian” and Eagles fan watching the games this year from the elder care facility.
As for John, he’s a self-described “worrier.” When Sean redshirted at Oregon State, John loved the ease of watching the games with no pressure in the family section. After Sean was inserted as starter the next season, John called the box office. He wanted to sit in the far corner of the stadium in the last row. Tickets in the family section were free and required no work on his end, but every year he’d call the ticket office to secure his seats at the top of the stadium.
Sean rarely played in the NFL — he threw just 110 passes over nine seasons in the league — so Sunday Ticket usually sufficed. When Sean was hired by the Packers, they were on national television frequently enough, and for the games they weren’t, John would drive to his local Buffalo Wild Wings, where he’d watch quietly and hope the quarterback play was up to snuff.
Last year, while watching a game at the restaurant, a few Green Bay fans in their 20s complained to John about Packers quarterback Jordan Love. The group had a laugh when John told them, no, he wasn’t from Green Bay, his son coached the quarterbacks.
“I’m going to call him tonight and tell him there’s some guys in Oregon who say he’s got a lot of work to do,” John joked.
This year, it’s back to Sunday Ticket. John, who was in town for a few days in August observing the Eagles and Sean during camp, said he’ll build a fire at home, watch the game in peace, and “keep our fingers crossed.”
His son’s new job comes with a lot of pressure. Patullo was the most criticized person in the building last year and eventually took the fall after the team’s first-round exit, so all eyes will be on Sean as the season gets underway.
Margaret’s older sister, John’s aunt, still lives in New Jersey and called John after Sean got the job.
She was excited Sean was in a new, high-profile job back where his family has roots. But her excitement also had a tinge of nervousness: “Hopefully everybody is nice to him,” she said.
The regular season is almost here! All the preseason talk has been about Jalen Hurts and new offensive coordinator Sean Mannion. But there’s somebody else who will have a big say in how high the Eagles fly. The Philadelphia Inquirer’s Jeff McLane explains why this year, in the absence of traded star A.J. Brown, DeVonta Smith has to take the next step, while also taking charge of the Eagles’ wide receivers group. Plus, Jeff dips into the mailbag for listener questions about Jalen Hurts and some key roster spots. Listen here.
