Chris Gray: Will this be final season?

Seahawks | Scouting the NFL Draft | Seahawks should be able to strengthen line | Seattle Times Newspaper: "Let's just say it once and for all — the Seahawks' offensive line hasn't been the same since Pro Bowl left guard Steve Hutchinson left after the 2005 season. The Seahawks have spent the past two seasons trying to find at least a solid replacement at left guard, and the latest move to that end is the signing of veteran guard Mike Wahle, a former Pro Bowler himself, in free agency.
If Wahle pans out, it will allow the Seahawks to use young Rob Sims as either the starter at right guard or the primary backup to both left and right spots. This offensive line was at its best in 2005, the Super Bowl year, but right guard Chris Gray is approaching 38 and his 16th, and likely final, season. Walter Jones is still the cream of the crop in the NFL at left tackle, but even the invincible begin to wear down some after 11 seasons."
