David DeCastro

DeCastro returns as the starting right guard after playing every snap last year. He has started 31 games for the Steelers over the last two seasons.

DeCastro will start at right guard for the Steelers this season.

DeCastro was regarded as one of the best offensive line prospects, but missed all but the final three games of his rookie season due to a knee injury. He'll get an opportunity to show why the Steelers took him with their first pick, starting at right guard this season.

The best interior lineman in the draft, DeCastro was expected to start the season at one of the tackle positions. Knee surgery killed that plan, and he was given the "designated for return" tag on injured reserve. DeCastro must spend at least six weeks on IR, but may not return until the 2013 season.
