The 49ers hope to make up for the free-agent losses of starters Perrish Cox and Chris Culliver with quantity. The team has six viable cornerbacks, and any two of them could wind up starting. Three of them, Tramaine Brock, Chris Cook, and Shareece Wright, are veterans and former starters. The other three, Dontae Johnson, Ken Reaser and Kenneth Acker, are rookies from last year. It will be the Wild West in terms of competition among those six. Meanwhile, safety might be the most talented and deepest area on the team. The best way to assess the secondary is by breaking down the major players.
