The Lions' website tentatively projects 2012 third-round pick Bill Bentley as the team's nickel back this season. Rookie Darius Slay is the favorite to man right corner, and Chris Houston is locked in on the left. In nickel packages, Bentley would replace a linebacker and cover opposing slot receivers. Bentley is recovering from two surgeries to repair a dislocated shoulder. He's expected to be healthy for training camp.
