From record-breaking college quarterback to NFL offensive coordinator
In short: Before coaching in the NFL, Sean Mannion was a prolific playmaker for the Oregon State Beavers. After a career spanning multiple NFL rosters and teams, he has transitioned from the field to the sidelines, moving from a professional quarterback to a high-level offensive strategist.
Sean Mannion's collegiate career at Oregon State was defined by record-breaking performances. During his 2013 season, he set a school record by throwing six touchdown passes in a single game against the Colorado Buffaloes on September 28. By the end of that year, he had achieved a Pac-12 Conference-record 4,662 passing yards for the season and a school-record 37 touchdown passes.
His senior year in 2014 saw him further cement his legacy by becoming the Beavers' all-time leader in both career passing yards and passing touchdowns. He also surpassed Matt Barkley to become the Pac-12's all-time leader in passing yards. Over his 43 career starts, Mannion accumulated 13,600 yards, 83 touchdowns, and 54 interceptions.
Following his collegiate success, Mannion entered the NFL via the 2015 draft, where the St. Louis Rams selected him in the third round as the 89th overall pick. His professional journey included stints with the Minnesota Vikings and Seattle Seahawks, often serving in backup or practice squad roles. After retiring from active play in February 2024, he transitioned into coaching, starting as an assistant for the Green Bay Packers in 2025 before being named the Philadelphia Eagles' offensive coordinator in early 2026.
Mannion's path illustrates the intense competition of professional football, where a standout collegiate star must navigate the complexities of being a backup and practice squad player before finding a new professional calling in coaching.
