Steltz, 27, will be returning for his seventh season with the Bears. He has been a mainstay in all four phases of special teams, and has appeared sporadically in the back end of the defense. He registered 23 total tackles in 2013.
McCray has spent four seasons with the Dallas Cowboys, where he was a special teams standout. Bears Special Teams Coach Joe DeCamillis was likely influential in bringing over his former player.
It remains to be seen whether any of the safeties signed will start for Chicago, presumably with FS Chris Conte, or whether they merely provide depth and special teams help. Mundy may be penciled in to start for now, but the Bears could still look at safeties early in the draft.
