Derrick Dockery a bad fit for zone blocking scheme

Derrick Dockery continued to plummet on the Redskins' depth chart Sunday. The veteran guard was inactive for the first time in his eight-year career. Washington's coaching staff determined in the preseason that Dockery, 30, was a bad fit for the team's zone blocking scheme. In the first two games, Dockery split time with Kory Lichtensteiger, 25, who was out of football during the 2009 season. Lichtensteiger started at left guard in Week 3 against St. Louis, ending Dockery's string of 111 consecutive starts. Dockery's role has continued to decrease since the Redskins lost to the Rams.
