They had to lose somebody and the ones they lost are not THAT big of a deal (and were all expected to go anyway)... they have replacements... the Seahawks will be fine.
They lost the running back that carried them for multiple years.
They have no receivers aside from Baldwin and a Graham who never fit in the offense and is coming off of a major injury.
They lost the right side of that defense with Irvin and Mebane gone.
They lost two offensive linemen.
Actually, they lost six starers. Lynch, Kearse, Irvin, Mebane, Sweezy, and Okung. I'm not liking Seattle's chances of reaching a Super Bowl.
