There's nothing unique in saying, if it ain't broke, don't fix it. And yet the Bears new defensive coaching staff faces a wholly unique challenge: Take a unit that seemingly can't work any better and find a way to do exactly that.
Fortunately, Deshea Townsend has a unique advantage entering his new post as Bears secondary coach this season. Sure, he inherited a group that led the league in interceptions and passer rating and includes three former first-rounders, two first-team All Pros and an ex-Pro Bowler in search of redemption.
But also at the disposal of Townsend, formerly a team captain at Alabama and 13-year NFL veteran junkyard dog defensive back, is a pair of Super Bowl rings as a member of the 2005 and 2008 Pittsburgh Steelers.
