While the Chicago Bears appreciate their place atop the NFC North standings, they know they won't enjoy the view for long unless some big changes occur on offense.
The Bears (4-1) had a bye over the weekend and took over the division lead because of Minnesota's 38-26 loss to the Washington Redskins.
Detroit (2-3) and Green Bay (3-3) both won on Sunday, keeping the Bears from getting too excited about their half-game lead over the Vikings (4-2) as they began preparations for next Monday night's game against the Lions.
The Bears play only their second divisional game of the season against the Lions.
To stay where they are, the Bears offense has to come around both in the running and passing games to complement a defense that has been dominant.
