Washington added offensive line depth, trading a sixth-round pick to Oakland for tackle David Sharpe and a seventh-round choice. Washington likes Sharpe's athleticism and length —he's 6-foot-6. Sharpe, a fourth-round pick in 2017, has started four games and played in 24. Geron Christian has been working with the starters at left tackle. Cornelius Lucas has been the primary swing tackle but Washington wanted more competition and depth.
