Tramaine Brock will be one of the the cornerbacks in the 49ers’ Nickel defense; we know that.
Who will be the other two starting corners?
The main candidates are Chris Cook, Chris Culliver and the rookie with the broken foot, Jimmie Ward. If the foot recovers and Ward earns a starting spot, he would be the Nickelback, and Cook or Culliver would start outside opposite Brock. I’m guessing Culliver would win the starting job over Cook. They both have the same problem — can’t turn and locate the ball — but Culliver has more experience than Cook in Vic Fangio’s system.
If the rookie with the foot, Ward, does not earn the starting Nickelback job during training camp, then who do you think the Niners’ three starting corners would be and which positions would they play?
Would you be surprised if Brock moved inside and Culliver and Cook played outside in the Niners’ Nickel defense? I think it’s a possibility.
