The Packers' Quest for Perfection: Green Bay's Three Biggest Roadblocks to 16-0

Green Bay has been nothing short of incredible all season. Beginning with their 42-34 win over New Orleans in Week 1, Aaron Rodgers and co. have rattled off nine straight victories. Only four of these wins have come by fewer than ten points, one of the main reasons why many believe that the Pack have the potential to be the first 16-0 NFL team since the Patriots in 2007.

But they aren't there quite yet. The Packers have seven games remaining, five of which will come against teams currently above .500. After their 45-7 drubbing of Minnesota last night, Green Bay seems all but invincible—especially considering the fact that their defense played at the same level as their high-powered offense.

Yet, it is likely that the Packers will meet their demise at some point this season. But when will the Packers fall? Here are the three games where Green Bay will be challenged most.

Week 12: at Detroit

Although the Lions have lost three of their last four, this team still possesses one of the league's most potent offenses. With star wide receiver Calvin Johnson, tight end Brandon Pettigrew and a possible return for speedy running back Jahvid Best looming, Detroit has all the firepower to put up points on Green Bay.

The Packers were stellar on D last night, but don't expect it to continue. Green Bay still has the league's 2nd worst pass defense. If Matthew Stafford has a big day, Aaron Rodgers will have to be flawless once again. I'm not saying that he's uncapable, but he's got to have a bad game one of these weeks, doesn't he?

This game will turn into a shootout. Stafford and the Lions just may be able to match Rodgers and the Pack score for score.

Week 13: At New York

The Giants may possess Rodgers' kryptonite. Justin Tuck, Osi Umenyiora, Jason Pierre-Paul and Chris Canty comprise the league's most dominant defensive line. These four will certainly be able to rattle the man most consider to be the league's best quarterback.

On the other side of the ball, Eli Manning is quietly developing into one of the league's most clutch quarterbacks. With a full slate of healthy receivers, Manning is exceptional. With a healthy Ahmad Bradshaw, Big Blue also has one of the league's best rushing attacks.

This game will be played at notoriously windy Met Life stadium. The Pack won't put up as many points when they're forced to pound the rock more than they have all season.

If this game is close in the fourth quarter, New York has the advantage. For there is one spot in which Eli excels almost more than any other quarterback in the league: in the clutch. Rodgers hasn't proven that he's capable of doing that yet....not that he's had to.

Week 16: Vs. Chicago

Green Bay topped Chicago 27-17 in week 3. That was before the Bears won four straight and established themselves as the top contender for a wild card spot in the NFC.

Chicago is a different team now. Their defense is playing fast, they're keeping Jay Cutler off the ground, and Devin Hester is, well, ridiculous. Keep in mind that Chicago is one of only three teams to hold Aaron Rodgers under 300 yards passing this season.

This game is at Lambeau Field, where Green Bay thrives in the cold. But the Packers very well may have locked up the No. 1 seed in the NFC at this point. 

One Hester punt return for a touchdown here, an Urlacher pick-six there. Who knows what could happen in this matchup of hated division rivals.
