After a disappointing playoff loss to the Los Angeles Rams, the Seattle Seahawks offensive line came back into focus as a major area to address during free agency and in the NFL Draft. They traded for Las Vegas Raiders guard Gabe Jackson, drafted tackle Stone Forsythe in the sixth round, and re-signed center Ethan Pocic as well as other backup depth.
In other words, not a whole lot really done in terms of overhaul to the actual starting lineup. Football Outsiders recently released a (paywalled) ESPN+ article outlining the biggest roster holes on each team, and while outside cornerback may not exactly be an area of comfort for depth at the moment, they went with center.
