Over the course of the last several years, the Chicago Bears used D.J. Moore, Isaiah Frey and Demontre Hurst at the nickelback position, but they produced mixed results.
In four seasons with the Bears from 2009 to 2012, Moore hauled in 10 interceptions, but his play dropped off significantly near the end of the 2012 season. According to Pro Football Focus, Frey played 515 snaps at nickelback in 2013 and finished the year with a minus-4.9 overall grade.
Frey played three games out of the slot for Chicago last season before he was cut after the team's Week 5 loss to the Carolina Panthers.
