Seahawks signed C Max Unger to a multi-year extension.
26-year-old Unger, a second-round pick in the 2009 draft, overcame durability issues in 2011 to start 15 games, grading out as Pro Football Focus' No. 17 overall center. PFF rated Unger as a strong pass blocker, but below-average run blocker. The Seahawks believe they've found their center of the future, and weren't going to risk losing Unger to free agency in 2013. Seattle's offensive line has a lot of potential this season, but it must stay healthy. Durability has been an issue at all five positions over the past few years, and we placed the O-Line 25th in our May rankings. A link to that column can be accessed below.
