Only six Seahawks players (including one on injured reserve) were with the team when Lynch last played there in 2015. There has been a huge turnover in player leadership. And there's a new run scheme under the direction of coordinator Brian Schottenheimer and line coach Mike Solari. But one thing that hasn't changed is coach Pete Carroll's commitment to a physical running game, which Lynch personified through parts of six seasons and two Super Bowl runs, including a win after the 2013 season. He retired after the 2015 season, only to inform the Seahawks a year later he wanted to return with his hometown Raiders. They worked out a trade, and he played parts of two seasons in Oakland before landing on IR last October with a groin injury.
