The question concerning the Packers offensive line heading into the season is how they'll replace departed veterans Scott Wells and Chad Clifton.
At center, the Packers are substituting one of the best centers in NFL history, Jeff Saturday, for one coming off a Pro Bowl season in Wells.
The risk in signing Saturday as a free agent is that he's on the back end of his career. He may not be the long-term solution in Green Bay, but as far as 2012 is concerned, the Packers are hoping to squeeze one more effective season out of him.
And at left tackle, Green Bay can only hope for the continued development of Marshall Newhouse, who spent the majority of last season playing in place of Clifton anyway.
Newhouse struggled at times last season, but he's still young enough to expect major improvement.
If he stagnates, the Packers can turn to last year's first-round draft choice, Derek Sherrod, but his status is in question after sustaining a broken leg late in 2011.
The rest of the offensive line is is good shape in the hands of a still-young trio of players: Bryan Bulaga, Josh Sitton and T.J. Lang.
Barring injury, there's no reason to think all three of them aren't going to continue to get better. Each one of them has All-Pro potential.
Others in the mix for roster spots include rookie Andrew Datko, interior backup Evan Dietrich-Smith and a host of others.
Given how much the Packers pass the ball, the performance of the offensive line will largely be tied to how well they keep quarterback Aaron Rodgers upright.
If the line is able to make strides in paving the way for successful rushing attack, all the better.
