The 49ers addressed arguably their biggest need today by signing former Eagles cornerback Nnamdi Asomugha to a one-year contract. The deal was first reported by NFL Network's Ian Rapoport.
Asomugha was once considered the NFL's premier cornerback, but at 31, he has slowed considerably. The Eagles, who signed him to a five-year, $60 million deal before the 2011 season, released him last month in a salary cap move.
Asomugha drew interest from the 49ers and Saints, but he opted to return to the Bay Area, where he once dominated his position with the Raiders.
The 49ers are need of help in the defensive backfield, having lost safety Dashon Goldson to the Buccaneers. The Niners gave up an average of 306 passing yards per game in their three postseason games. They were beaten by Joe Flacco's Ravens in the Super Bowl.
The 49ers have also looked at former Packers cornerback/safety Charles Woodson, but have not made a move to sign him.
