Several offensive linemen have separated themselves from the pack of backups: JC Tretter, Jason Spriggs, Lane Taylor and Don Barclay.

And Barclay looks more confident in his post-surgical knee than he was last season. He replaced Tretter and played the rest of the game (73 snaps) at center, and his ability to fill in anywhere on the line in a pinch will make him hard to cut. Barclay never has been especially athletic, but he’s moving his feet better now that he’s nearly two years removed from surgery.
