The Green Bay Packers again have a defense that they believe can win games for them.

This year, the Aaron Rodgers-led offense isn't as unstoppable, which is why the NFL MVP appreciates the defense's return to form.

Last year's defense ranked dead last in the 32-team NFL in yards allowed, gave up more passing yards than any defense in NFL history and finished 19th in scoring defense.

In 2012, the defense entered this week's games 16th in yards allowed per game (343.9), 21st in yards passing allowed per game (244.4), 11th in yards rushing allowed per game (99.5), 10th in scoring defense (20.7 points per game) and second in sacks (33). Coach Mike McCarthy now acknowledges that last year's defense simply wasn't good enough, prompting him to focus on making his team more balanced.
