If not for one of the more boneheaded calls in National Football League history, Sherman would be leaving the Great Northwest as a two-time Vince Lombardi Trophy victor.
Richard Sherman reportedly is moving closer to finding a new home.
Sherman turns 30 on March 30.
Schefter didn't rule out the possibility of Sherman staying in the NFC West and joining the 49ers.
The talented, brash defender has been one of the faces of a team that appeared in two Super Bowls and won one, success built on a hard-hitting defensive identity and the vaunted "Legion of Boom" secondary. He has since undergone surgery on his other Achilles.
The Seahawks could also re-sign DeShawn Shead, who like Maxwell is also an unrestricted free agent. Sherman expects to be ready for the regular season but could be limit in August for training camp and parts of the preseason.
Although the 49ers are in desperate need of a strong cornerback, there are some concerns about Sherman's health and age.
Cap space isn't an issue for the 49ers, who have $70 million, more than all but four other teams, even after recently re-signing quarterback Jimmy Garoppolo to a five-year, $137.5 million deal. 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".
