Editor’s note: Insider Matt Maiocco will be providing position-by-position breakdowns each day leading up to 49ers training camp, which opens with their first full-squad practice on Aug. 1.
Who they have: Tramaine Brock, Shareece Wright, Dontae Johnson, Keith Reaser, Chris Cook, Kenneth Acker, Marcus Cromartie, Leon McFadden, Mylan Hicks
Who they lost: Chris Culliver, Perrish Cox, Cameron Fuller
Looking back: Despite a rash of injuries, including starter Brock being limited to approximately 12 healthy snaps the entire season, the cornerbacks were outstanding. Cox and Culliver combined for nine of the 49ers’ NFL-best 23 interceptions.
