Quick note on Seahawks roster moves

Posted by ESPN.com's Mike Sando

The Seahawks placed center Cory Withrow on injured reserve and signed rookie free-agent safety Nate Ness, formerly of the Jets.

Adam Caplan of Scout.com has the report. He refers to the Seahawks' lack of depth on the interior of their offensive line, but I think that's a relative thing. The depth becomes less of a problem as rosters shrink from 80 to 75 to eventually 53 players.

Chris Spencer is injured, but Max Unger, Steve Vallos, Rob Sims, Mansfield Wrotto and Brian De La Puente are all interior players. Tackles Sean Locklear and Ray Willis have experience at guard, although moving them there would leave the team without tackles -- which points to the more serious depth concern for Seattle until Walter Jones returns.
