"You can't play quarterback, period, if you can't take care of the football," McCarthy said. "If you look at our history here as far as turnover ratio, the amount of time and energy we put into drilling and taking care of the football, it's been a real strength, and it's a tremendous strength of Aaron Rodgers and how he plays the position. DeShone needs to learn from those two plays."

On the flip side, the Packers' defense did not get a turnover against the Bears until the game's final play, which made the comeback more difficult, yet the defense got the job done without the big momentum swing a turnover can provide.

"It's hard to overcome the turnover ratio. We were minus-2 up until the last play of the game," McCarthy said. "To be minus-2 and win that game, that's not the norm. It points to the ability of our defense to keep us in it and keep points off the board."

Perhaps the biggest negatives defensively were the three roughing-the-passer penalties. McCarthy said the way they were called, it's clearly an emphasis for the officials and the Packers must adjust accordingly.
