The 49ers reportedly have talked to every top-level potential free-agent cornerback. They know they have to make upgrades in the secondary. Defensive end Justin Smith is getting closer to the end of his career, and the 49ers' pass rush struggled in the playoffs. Another edge rusher or someone who can push the pocket from the interior should be on the team's wish list. A wide receiver who can stretch the field would help, although the team is hoping A.J. Jenkins, last year's first-round draft selection, will fill that role.
