RENTON — Maybe defensive end Branden Jackson has already appeared to show a lot to the Seahawks this preseason.
Jackson has one of the only four sacks Seattle has gotten in the first three preseason games, leads the team with three quarterback hits and is tied for the team lead in tackles-for-a-loss with two.
But Thursday, in the final preseason game for the Seahawks at CenturyLink Field against the Raiders, Jackson is going to have to make Seattle coaches notice him all over again to assure a spot on the team’s 53-man roster heading into the regular season.
