This weekend former Chicago Bears safety Chris Harris announced his retirement from the NFL through social media. He tweeted his intentions and elaborated even more on his Facebook page. Harris was a member of the Chicago Bears on two separate occasions, from 2005-2006, then again from 2010-2011, and now it looks as though he'll be starting his coaching career in Chicago.
According to Dan Pompei of the The Chicago Tribune, the Bears have hired Chris Harris as a defensive quality control coach. Besides the obvious Chicago connection, Harris briefly played for new defensive coordinator Mel Tucker last year in Jacksonville.
A quality control is basically an entry level position on an NFL coaching staff. Some responsibilities of the position are, film work, charting plays, scouting the opponent, and also on field coaching. My guess is Harris will be working with the defensive backs, and his prior experience with Tucker will aide the transition.
