Steelers strengthen offensive line, sign Seumalo, sources say

The Pittsburgh Steelers bolstered their offensive line on Saturday night, acquiring a full-time, statewide starter.

Former Philadelphia Eagles guard Isaac Seumalo has signed a three-year contract with Pittsburgh, sources have told ESPN.

Seumalo is the second Steelers offensive line to sign in free agency, joining Nate Herbig, who spent three years with the Eagles before a one-year stint with the New York Jets. Both Herbig and Seumalo have ties to Steelers first-year assistant general manager Andy Weidl, who spent six seasons in the Eagles front office, including three as vice president of player personnel.

Left guard for most of his career, Seumalo moved to right guard for the 2022 season and provides the Steelers with flexibility inside the line. His addition also creates additional competition for third-year lineman Kevin Dotson for a starting left guard spot, or even James Daniels at right guard.

Seumalo missed a lot of time with injuries in the 2020 and 2021 seasons, but bounced back to play in all 17 regular season games for the Eagles in 2022 and was part of a unit that finished second in the win rate of ESPN’s rushing block (75%) and fifth in rushing yards per game (147.6).

He has the quickness of foot to redirect defenders and the control of the body to fight against powerful rushers and create a solid base in the pocket. His passing block win rate of 93.6 percent ranked 15th among all guards this season, while his running block win rate ranked 20th.

Seumalo, 29, was a third-round draft pick by the Eagles in 2016 at Oregon State. He started 60 games in seven seasons at Philadelphia, helping to build one of the best offensive lines in football during that span.

He is credited with helping shape the game plan in the offensive line room with position coach Jeff Stoutland and center Jason Kelce.
