The Detroit Lions have the best chance to end the Packers' perfect regular season in Week 17.

It is still highly unlikely because the game is at Lambeau, but I don't see the Raiders, Chiefs, or Bears beating them either in the next few weeks; not to mention Jay Cutler and Matt Forte won't be playing in that Christmas Day matchup.

The Lions, however, will have Ndamukong Suh back to face the Packers and they'll definitely give it their best shot because they could be fighting for a playoff spot. If Green Bay rests its starters then anything can happen.

The Saints have improved since their Week 1 battle with the Pack and they have the offensive firepower to beat GB in a shootout. This is the only team I see taking down the Packers if the two meet in the playoffs, especially with how poorly their defense is playing.

The team with the best chance to ruin the Green Bay Packers perfect season has to be the New Orleans Saints.

Even though Green Bay beat New Orleans in Week 1, it came down to a last second play. The Saints are one of the hottest teams in the league right now, and if any team's offense can keep up with the Packers, it's New Orleans.

It would no doubt be a high scoring game, and if I had to pick a defense to eventually make a stop if these two teams were to meet again, I'd have to pick New Orleans.

The Packers have a great chance to ride into the postseason at 16-0, but could face a very tough playoff game against the New Orleans Saints. It is hard to imagine anybody beating the Packers at Lambeau, but the Saints have a better chance than anybody else. They are able to score as well as any team in the league and could pressure on the Packers secondary. The Packers struggle against opposing tight ends and Jimmy Graham is a nightmare match-up. If the Saints protect the ball, they can hang with the Pack.

I would have to take the Steelers in a Super Bowl rematch. The Packers should have no problem finishing the regular season undefeated with wins over Oakland, Kansas City, Chicago and Detroit. Drew Brees and the Saints have a good chance to give the Pack a run for their money in the playoffs, but I can't see anybody beating Green Bay at Lambeau in January.  The Steelers have the ability to put pressure on Aaron Rodgers and can challenge the Packers' secondary with their vertical attack.  Plus, Ben Rothlisberger, James Harrison and Co. would come into the game extra motivated by the prospect of avenging last year's Super Bowl loss.
