Sherman was released with a failed physical designation which allows him to be eligible for a $1.15 million injury guarantee if he never plays again.
Sherman also would be in a similar defense - San Francisco's defensive coordinator is Robert Saleh, who was a defensive quality control coach with the Seahawks from 2011-13 and has installed a scheme similar to that run by Pete Carroll in Seattle.
Still, the Patriots would be well-served to explore the possibility of bringing Sherman into the fold. Condotta says that the team was interested in trying to get Sherman to agree to a pay cut but that he "balked" at such a proposal.
Sherman was part of five Seahawks playoff teams, appeared in two Super Bowls, and helped Seattle win Super Bowl XLVIII.
Sherman had surgery to fix his right Achilles in November.
Sherman has had to battle some injuries in recent years, but when healthy, he is still one of the better cornerbacks in the league.
While T.J. Carrie was the best cornerback the team had last season, he comes into the offseason as an unrestricted free agent.
The 49ers are in need of cornerbacks and are expected to land a veteran in the coming week whether it is Sherman or someone else.
The cost-cutting moves will give the Seahawks an estimated $38 million in available salary cap space - they had $13 million at the beginning of the week. He told SI.com's Albert Breer the Seahawks "wanted the financial flexibility going into free agency but expressed that they wanted me to return and will be in contact".
