ASHBURN - At the end of last season, one of Washington Redskins coach Jim Zorn’s biggest concerns was right tackle, a key position that opens holes for running back Clinton Portis and keeps quarterback Jason Campbell on his feet. Five months later, when the Redskins took the field yesterday for the final set of spring practices, the story was the same.

On Monday, quarterback Jason Campbell left Redskins Park for the final time this year, a duffel bag slung over his shoulder while he held on to a poster commemorating his selection as player of the week. Offensive tackle Jon Jansen had to exercise a little more care in cleaning out his locker. The 32-year-old may have played his final game with the Redskins.
