The Seahawks decided Monday not to match the seven-year, $49 million offer sheet on Steve Hutchinson, allowing the All-Pro guard to go to the Minnesota Vikings. The seven-day deadline to match the Vikings' seven-year, $49 million offer sheet expired at midnight ET Monday. The Seahawks did not notify Hutchinson, the Vikings or his agent, Tom Condon, that they were going to match the offer. By letting the deadline pass, Hutchinson became property of the Vikings. As the deadline came and went, the Seahawks added a big-time piece to their defense by reaching a contract agreement with former 49ers linebacker Julian Peterson, one of the premier players still in the unrestricted free agent market. The seven-year agreement, if completed, is expected to total more than what the Vikings offered Hutchinson. It will pay Peterson, the No. 4 player overall in ESPN.com's free agent rankings, as much as $55 million over seven seasons, and includes $18.5 million in bonuses. It is not known if the acquisition of Peterson will take the Seahawks out of the running for Jets defensive end John Abraham. The Seahawks are locked with Atlanta in a tug-of-war over the three-time Pro Bowl end; they have agreed with the Jets on trade compensation, but they have been unable to strike a contract agreement with Abraham, whose preference is to play for the Falcons.
