Tramaine Brock, the 49ers' No. 4 cornerback last season, will sign his one-year tender as a restricted free agent on Monday, a source said, which means the team returns its top five cornerbacks from a year ago.
The 49ers also added veteran Nnamdi Asomugha, a three-time Pro Bowl selection while with the Raiders before a disappointing two seasons with the Philadelphia Eagles. But that does not mean the 49ers are set at this position.
Who's here: Carlos Rogers, Tarell Brown, Chris Culliver, Nnamdi Asomugha, Tramaine Brock, Perrish Cox
Draft needs: The 49ers had one of the best pass defenses in the NFL during the regular season. Then, things fell apart in the playoffs. (Of course, quarterbacks Aaron Rodgers, Matt Ryan and Joe Flacco and their talented receivers had something to do with that.) The 49ers surrendered nearly 100 yards per game more in their three playoff games than during the regular season. Opposing quarterbacks completed 59.4 percent of their passes and posted a lowly 78.0 passer rating in 16 regular-season games. In the playoffs, the completion percentage against the 49ers was 68.4 and the passer rating was 109.5.
Good fits: The 49ers have given indications they want to get bigger and more physical at the cornerback position to match up better against tall wide receivers. At 6 foot 2, 185 pounds, Jonathan Banks (Mississippi State) could warrant consideration with one of their top picks. D.J. Hayden (Houston) is moving up boards as an early-round prospect. He visited the 49ers this week. Tharold Simon (LSU), also 6-2, is an intriguing prospect, as well. Some other bigger cornerbacks who could be tempting for the 49ers include Blidi Wreh-Wilson (Connecticut), David Amerson (North Carolina State), Logan Ryan (Rutgers), Marc Anthony (Cal) and Aaron Hester (UCLA).
