The only competition underway on the offensive line is the one at center, where JC Tretter and rookie Corey Linsley are engaged in a battle for the starting job.
But it may be a competition in name only, even if Mike McCarthy hasn't yet named a starter, as Tretter has run with the ones in both preseason contests and performed well each time. Linsley, on the other hand, had two penalties against St. Louis, one that negated a touchdown.
"I think JC's off to a great start," McCarthy said after the matchup against the Titans, per ESPN.com's Rob Demovsky. "I think the Tennessee game was definitely impressive. I want to see him stack success anytime you play well."
He did it again against the Rams, running the no-huddle offense with Aaron Rodgers and the ones without a hitch. His experience in the system and chemistry with Rodgers should give him the final push to lock up the starting spot against Seattle in Week 1.
Elsewhere along the line, after struggling to find the right personnel groupings in recent seasons, McCarthy and offensive line coach James Campen appear to have nailed it with Bakhtiari, Sitton, Lang and Bulaga.
The Packers have likely the NFL's best guard pairing in Sitton and Lang. Both finished in the top 15 among all NFL guards in 2013 in Pro Football Focus rankings (subscription required), with Sitton grading out as the No. 2 guard overall. Sitton allowed only one quarterback sack in 2013.
More so than most other units aside from quarterback, the offensive line will need each of its starters to remain healthy in 2014. The loss of Don Barclay for the season brings the depth of this group into serious question as the second-stringers, including Derek Sherrod, struggled against St. Louis.
