GREEN BAY, Wis. -- No matter where Bryan Bulaga plays, regardless of whether David Bakhtiari remains at left tackle and whoever ends up playing center, the Green Bay Packers have more stability on their offensive line than they did last offseason.

It was nearly a year ago that coach Mike McCarthy and offensive line coach James Campen revamped the line by changing positions for four of the five starters. Bulaga and Josh Sitton switched from right tackle and right guard, respectively, to the left side. Left tackle Marshall Newhouse was moved to the right side (where he failed to beat out Don Barclay), and left guard T.J. Lang moved to right guard.

Only center Evan Dietrich-Smith remained in his regular spot.

This season, perhaps only the center position is up in the air with Dietrich-Smith scheduled to be a free agent next month.

It all depends on where the Packers decide to play Bulaga, who missed all of last season after he sustained a knee injury last August in training camp.

Although McCarthy said last week at the NFL scouting combine that he had not finalized his plans for Bulaga, he later told the Green Bay Press-Gazette that Bakhtiari performed well enough last season as a rookie that the Packers appear to be set to keep him at left tackle.

“If you look at our depth chart right now this is the best group of offensive linemen from a depth standpoint that we’ve had in my time in Green Bay,” said McCarthy, who is entering his ninth season as head coach. “There’s a lot of good things to build off of with our offense.”

Moving Bulaga back to the right side would not be a major adjustment. He excelled at right tackle from 2010-12 and never even made it to his first preseason game as a left tackle. Bulaga spent most of the season rehabbing his knee in Florida but is expected to return to Green Bay for the offseason program in April.

“He’s on time and he’s hit his targets,” McCarthy said of Bulaga’s rehab. “But as I’ve told Bryan when he left in the exit interview [after the season], I’ll be in touch with him to let him know what our plan is whether it’s the left side or the right side.”

A potential change at center would not impact any of the other projected offensive line starters. Lang is not a candidate to move to center even though he filled in there for Dietrich-Smith for parts of two games last season.

The only other possible starting center on the Packers’ roster is JC Tretter, a fourth-round pick last year who did not play at all as a rookie after sustaining an ankle injury in the offseason.
