The NFC North is blighted by some of the softest pass defense in the NFL. The Green Bay Packers took division with a 15-1 record last season, despite ranking last in the league against the pass.
Here are the major weaknesses troubling the NFC North heading into the 2012 NFL season:
Chicago Bears: Offensive Line
Although the Chicago Bears ranked 28th in pass defense last season, count on their Tampa-2 scheme to tighten things up in 2012. The Bears' real weakness is the play of their offensive line.
Chicago's front five surrendered 49 sacks last season, after giving up 56 in 2010. Quite how those numbers recommended line coach Mike Tice for a promotion to offensive coordinator, is anybody's guess.
The Bears have some talent at the skill positions, particularly running back Matt Forte. They traded for wide receiver Brandon Marshall and added another tall flanker in the draft, with the selection of Alshon Jeffery.
However, all of those weapons will be rendered moot, if the Bears don't perform better up front.
