Trestman's possible DC

UPDATE: ESPN NFL Insider Adam Schefter says the Bears have announced that they have indeed reached an agreement with Mel Tucker to fill their open DC position.

Out of the eight new HCs around the league this offseason, seven come from an offensive background while just one is from the defensive side (Gus Bradley). New Chicago Bears HC Marc Trestman and the other six, therefore, must find themselves someone to run the show on the other side of the ball, and it appears that there is a particular candidate that may be headed to Chicago soon.
