The Packers defense picked off Jay Cutler four times and sacked him seven times in the win.
Clay Matthews led the Green Bay defense with 3.5 sacks and continuously wreaked havoc on the abysmal Bears offensive line.
Matthews was the catalyst to the Packers defense all game long, and the rest of the team fed off the momentum he generated while he showed off his biceps after he slammed Cutler to the ground.
The Bears simply had no answer for him, and it showed.
Cutler was held to 126 yards on just 11-of-27 passing, and the Packers made Brandon Marshall invisible all game long. Marshall had nine catches against the Colts, but didn't even catch his first pass against the Packers until the closing minutes of the fourth quarter.
On Sunday, the Packers gave up 377 yards to the 49ers. On Thursday, they held their rival Bears to just 168 yards of total offense.
Charles Woodson and Tramon Williams both came up huge for the Packers on Thursday night. Williams picked Cutler off twice, and Woodson helped silence the Bears quarterback that wished the Packers defense "good luck" just a few days ago.
Green Bay's defense was the anchor to its Thursday night victory. Aaron Rodgers looked human finishing with only 219 yards and one touchdown, but it was the defense that stole the show for the Packers.
Everyone knows how explosive the Packers offense can be, but after a forgettable 2011 defensive performance, Thursday night's victory was a statement for the rest of the league that Clay Matthews and co. is a force to be feared.
If the Packers can continue to pressure the quarterback and generate turnovers for the rest of the season, they'll give the 49ers a run for their money come playoff time.
