A sixth-round pick in 2012, Frey played all 16 games last season as the club’s nickel corner and started in six contests. Frey contributed 62 tackles and two pass breakups, but failed to force any turnovers as he played the majority of the season with a broken hand.
The Bears parted ways with Hardin after the 2013 preseason finale after he suffered a fractured scapula. Emery admitted to miscasting Hardin as a safety, despite him spending his college career at Oregon State as a cornerback. The club cut Rodriguez in June 2013 on the heels of his second offseason arrest.
McCoy, meanwhile, was let go during final cuts in 2012.
Brown was also a part of the 2012 class, but joined the Bears as an undrafted free agent out of Troy. Brown played in five games for the Bears in 2012 and started the final three outings at left guard, but was inactive last season for all 16 contests.
