Stewart(26) is a 5'11, 214lb safety who started 14 games this past season for the Baltimore Ravens. There he totaled 53 tackles, 3 pass deflections, 1 interception, and 1 forced fumbles. In his five-year career, he has totaled 200 tackles, 21 pass deflections, 2 interceptions, and 4 forced fumbles.
According to Pro Football Focus, Stewart played 71.2 percent of all Ravens defensive snaps in 2014, earning a season overall rating of 3.0. He came up big in the playoffs with a 4.0 rating for their two games for the third-best rating of any safety in the playoffs.
I believe Stewart will be penciled in as the starter at free safety for the Broncos right now. However, veteran David Bruton, and corners Omar Bolden and Kayvon Webster may also get looks at safety. I would also look for the Broncos to draft at least on safety in this Aprils NFL Draft.
