Cranking up the NFL's oldest rivalry for the 187th regular-season meeting, both teams have tons of question marks.
Chicago can't run the ball, which puts an extra burden on Jay Cutler and his targets: WRs Brandon Marshall and Alshon Jeffery, TE Martellus Bennett. So far, they have handled the challenge well.
Green Bay also can't run, and the protection for Aaron Rodgers has been inconsistent. Even with his escapability, Rodgers has been sacked nine times.
With a victory, the Packers will join the Bears as the only franchises with 700 regular-season wins.
