Across from Sitton, Lang is another staple at the guard position.
Both guys have been recognized as being two of the best and they just go out and do their jobs, week-in and week-out.
Lang, too, has been struggling with back and knee issues.
To add to it in 2015, Lang suffered a shoulder injury that needed surgery in the offseason. Though he did play through the injury for most of the year, it was his strength of will that really kept him in action.
With so much depletion on the offensive line, the Packers lacked the depth to cover for all of the ailing linemen.
Lang should be fully recovered and ready for action when the team goes to training camp, but his injury-plagued seasons (as with Sitton) does seem to be a cause for concern for the Packers moving forward.
