Chase Roullier was the Redskins ironman on offense last season. He was the only player in on every offensive snap, and was rewarded for it with an extra $481k.
The Redskins offensive line was devastated by injury again last year. Both starting guards were lost for the year when Shawn Lauvao(ACL) and Brandon Scherff(pec) went down. Both starting tackles were limited by injuries. And when backups started dropping, guys were getting signed off the street to play.
Roullier told the Washington Times that he had shoulder surgery to deal with an injury that has bothered him the last few years.
