Seth Ryan joined the Lions as the team's assistant wide receivers coach in 2021 after spending the past four seasons (2017-20) with the Los Angeles Chargers, serving as a coaching intern from 2017-18 and an offensive quality control coach from 2019-20.
In his first season in Detroit, Ryan assisted in multiple aspects of the team's special teams, working closely with gunners and the wide receiver corps. With Ryan's assistance in the wideouts room, Lions rookie WR Amon-Ra St. Brown saw impressive success in his debut season. St. Brown finished his rookie season with 90 receptions for 912 yards (10.1 avg), both the most for a rookie in Lions history. His 90 catches finished the season for the second-most in the NFL, while he finished fifth amongst rookie in receiving yards. In only his first NFL season, St. Brown had six-straight games with at least eight receptions, the longest streak in team history and the longest for a rookie in NFL history.
During his stint in L.A., Ryan worked primarily with the team's wide receivers and helped guide WRs Mike Williams and Keenan Allen (three) to 1,000-yard seasons in that span. Allen made the Pro Bowl in all four years working with Ryan and produced a franchise-record 104 receptions in 2019. Allen totaled 403 receptions in that span, the third-most in the NFL, and his 4,780 yards ranked as the sixth-most. He was also one-of-three players to produce three 100-catch seasons in that range.
Ryan was a wide receiver at Clemson from 2013-16 and helped the Tigers win the 2016 College Football Playoff National Championship. The Tigers also won two ACC titles, the Orange Bowl and the Fiesta Bowl over his time there.
The son of former NFL Head Coach Rex Ryan, he is married to his wife, Meg.
