By landing former Titans defensive lineman Jason Jones, Seahawks have finally signed a free agent who wasn't on the roster last season. Jones has experience at both defensive end and tackle, and there's a good chance he'll compete with Alan Branch for the starting 3-tech position. Branch is strong against the run, but doesn't find his way into the backfield very often. If Jones proves to be an upgrade over him, then great; if not, well, Jones is only signed to a one year contract.
In other news, Bears CB Corey Graham is scheduled to visit the Seahawks on Sunday. Graham has played all five seasons of his career with Chicago, and last year he notched three interceptions despite not starting any games (he does have ten career starts, nine in '08 and one in '09) and capped off the year by going to the Pro Bowl as the NFC's special teams player. If the Seahawks are looking for a player who is decent in spot duty and excels at special teams to replace Atari Bigby, Graham isn't a bad choice.
UPDATE (2:56): According to the Miami Herald, the Dolphins are still hoping to sign Matt Flynn for a bargain price. Flynn is supposedly going to make his decision by Monday, and if he ends up choosing Seattle it'll be due in no small part to Miami GM Jeff Ireland's poor negotiating. I'm honestly not sure why he hasn't been fired. The Dolphins still have tons of holes on their roster after four years with him at the helm, and, unlike Bill Polian in Indianapolis, Ireland hasn't had a Peyton Manning to hide his shortcomings behind
