The Lions are the best team in the NFC right now...but honestly I think the NFC could see any one of 5 teams wind up in the Super Bowl and it wouldn't be a dramatic surprise (Det, Philly, GB, Vikes, Bucs). The top 3 NFC North teams have a total of 3 out-of-division losses between them 13 games in, and those close losses were to the Eagles in Brazil Week 1, @ Rams, and Bucs in Week 2. There is still a full month of the regular season for a few key injuries to happen on contending team rosters that could completely flip the playoff picture, too.
If Love gets hot with a healthy receiving corps and Jacobs stays healthy, the Packers are as good as anyone else in the NFL and it doesn't matter where the game is played - even with an at-times shaky defense that struggles to generate a pass rush. That being said, the youth on the Packers roster and an ill-timed Love INT make them beatable for any potential playoff opponent.
