The offensive line of the Packers was hit hard by injuries in 2012, and that situation severely tested the depth on the line. Right tackle Bryan Bulaga missed the latter half of the season due to a hip injury. Bulaga was the team's first-round draft pick in 2010.
The first-round draft pick in 2011, offensive tackle Derek Sherrod, missed all of the 2012 season due to a broken leg suffered late in the 2011 season. In addition, left guard T.J. Lang missed a game due to an ankle injury. Lang injured the ankle after he switched to right tackle after the hip injury to Bulaga.
That situation put Evan Dietrich-Smith in at left guard, while undrafted rookie Don Barclay became the right tackle after Lang's injury.
After Lang came back, he returned to left guard and Barclay stayed in at right tackle. Dietrich-Smith became the starting center in Week 16 of the season, replacing veteran Jeff Saturday.
Right guard Josh Sitton and left tackle Marshall Newhouse both started all 16 games at their respective positions.
Bottom line, there were issues on the line, even besides the injuries. For one thing, Newhouse did not play much better at left tackle last year compared to 2011.
Quarterback Aaron Rodgers was sacked 51 times, and Green Bay's rushing attack was only 20th in the NFL in 2012.
If everyone is healthy, the Packers will be bringing back quite a depth chart for the offensive line. If the season started on Friday, from left to right, you would have Newhouse, Lang, Dietrich-Smith, Sitton and Bulaga. The reserves would include Sherrod, Barclay, guard Greg Van Roten and offensive tackle Andrew Datko, who spent his rookie year on the practice squad.
The Packers have to address the lack of depth in the interior of the line, notably at center. The perfect candidate would have the versatility to play all the line positions—someone like Barrett Jones of Alabama or David Quessenberry of San Jose State.
Such a player could fill in at center or guard or even play offensive tackle if the situation is warranted.
