Offensive line is another position grouping where it's difficult to put much stock in a strict depth chart just because most of the players have to be able to play more than one position.
But as far as the starting lineup goes, Marshall Newhouse takes over for long-time veteran Chad Clifton, who was released this offseason.
Newhouse displayed potential replacing Clifton in a relief role last season, but he also gave up too many sacks. He has to become more consistent.
The bookend tackle on the right side will be Bryan Bulaga. Coach Mike McCarthy thinks he's on the verge of becoming a Pro Bowl player.
Backing up each of the tackle positions are 2011 first-round draft choice Derek Sherrod and rookie Andrew Datko.
Assuming Sherrod recovers from the broken leg he suffered late last season, he can be a swing tackle on both the right and left sides. And if he isn't fully healed, Datko can do the same thing.
T.J. Lang and Josh Sitton will be the starting guards, and both are in the prime of their careers.
Neither Lang nor Sitton is in danger of losing his job, but the second-string guard spots are up for grabs.
Evan Dietrich-Smith has an opportunity to back up not only at guard but center as well. The experience he gained last season will only help him.
Meanwhile, Ray Dominguez doesn't play center and couldn't cut it as a tackle in training camp last year. So if he's going to stick as a guard, he's going to have to border on being dominant.
At center, free-agent signee Jeff Saturday takes over for Scott Wells. There's a worry that Saturday is too old, but the Packers are just looking to squeeze one good year out of him, maybe two.
Competing with Dietrich-Smith to become Saturday's backup is Tommie Draheim. The Packers showed how much they like Draheim by giving him an $8,500 signing bonus, most among all their undrafted rookies this season.
