Russell Okung

The oft-injured Okung has never played a full season, missing two games last year with calf and chest injuries. When he plays, though, he's a stalwart at left tackle, though he allowed as many sacks last year (3.5) as he did in the previous two years combined (23 games). Health, and more consistency, is imperative this year for Okung, who will anchor a weak offensive line that will start mediocrity at left guard. A free agent at year's end, Okung might not be back next season if the Seahawks aren't willing to pay top dollar.

In four seasons, the injury prone Okung has played in only 45 of 64 games. He was limited to eight games last season because of a toe injury. When he's on the field, though, he's one of the league's best left tackles. A 2010 Pro Bowler, Okung has allowed 3.5 sacks the last two years (23 games).

The sixth overall pick in the June draft, Okung replaces the HOF-bound Walter Jones at left tackle. Okung will have his rookie struggles, but the Seahawks need him to develop quickly.
