49ers' Secondary Shakeup: Ambry Thomas Rises, Isaiah Oliver Slips

The San Francisco 49ers have reopened the competition for the nickel back position after Isaiah Oliver failed to secure the role during training camp and had a shaky preseason opener. Defensive coordinator Steve Wilks stated that they may use multiple players depending on the offensive skill set they face in nickel situations. They have been experimenting with moving Deommodore Lenoir from cornerback to nickel and have seen progress from young cornerbacks Samuel Womack and Ambry Thomas. The team is focused on creating competition and finding the best mix for the position.
