Beyond Maurkice Pouncey at center and David DeCastro and Ramon Foster at the guard spots, things could change a whole lot between now and the first regular-season contest of the 2013 season. Pittsburgh's offensive line is under new management, as Jack Bicknell, Jr. takes over as position coach.
Bicknell favors linemen who are athletic and versatile, so bigger players like Max Starks are not going to be kept around or re-signed. Luckily, Pittsburgh has put a premium on those qualities in recent drafts.
Ramon Foster was brought back and will be a valuable starter at left guard. Foster is under-appreciated but finally got a contract that shows how important he's become to Pittsburgh.
The tackle spots are the biggest issue. Marcus Gilbert spent the majority of last season injured. He should be solid at right tackle but may be more effective on the left side where Mike Adams is currently projected.
Adams showed little in his first season and could be overcome by second-year man Kelvin Beachum, who played well at guard as an injury substitute.
The other backups aren't very enticing and the free-agent market isn't very good here. The draft class along the offensive line is very deep and Pittsburgh should be able to find some value there whether they look there early or late.
