Broncos' safety Darian Stewart arrived in Denver as a relative unknown. He was the lone defensive starter coming from outside of the Broncos' already tight-knit defense.
Stewart had flashed talent during his five years in St. Louis and Baltimore, but when he arrived, he was just a guy to replace Rahim Moore.
Fast forward to December and Stewart has been the Broncos' best offseason pickup. He's an upgrade over Moore and a stabilizing force on a defense bitten by injuries and suspensions.
"He's our quarterback in the secondary," defensive coordinator Wade Phillips said.
