T.J. Lang

Lang is the Packers top backup on the offensive line.

The Green Bay Packers don’t seem overly concerned about left guard Daryn Colledge’s knee injury, but if he’s unable to play this weekend, T.J. Lang would start in his place.

Lang has played his way into the backup job at both tackle positions, but wasn’t previously the primary backup at left guard. That was Jason Spitz.

When Colledge went down against Detroit, Spitz came in for him, but played terribly before getting replaced by Lang. Spitz looks like he’s played himself out of that role. He’s now only listed as a backup at center.

Lang, although he wasn’t all that effective against Detroit, is now Colledge’s primary backup as well. Although he’s a natural tackle, Lang played left guard briefly during training camp.

Spitz, on the other hand, seems to have regressed. In 2008, Spitz was the full-time starter at right guard and played fairly well. In 2009, he opened the season as the Packers starting center, a position he held until getting injured. Spitz’s performance at center was uneven and he never regained the job from Scott Wells.

Now, Spitz can’t seem to do anything right. Fortunately for the Packers, they probably won’t have to worry about it much longer.

Spitz is in a contract year and he’s given the Packers no reason to re-sign him.
