Still too soon to say
Of course the Packers stand a chance of going undefeated in the regular season. Will they? I doubt it.
We're just five weeks into the season, and so many things can happen over the next 11 games — key injuries, a letdown, or simply a good team that's better than Green Bay on that particular day. Plus, there's the likelihood that if the Packers were to build a comfortable lead in the division — no guarantee, considering how Detroit is playing — they would take their foot off the pedal, rest some starters, and coast into the postseason.
If Rodgers stays healthy
If Aaron Rodgers, who is clearly the best quarterback in the NFL, avoids a significant injury, the Pack could become the second team in NFL history to finish the regular season 16-0.
To that end, the loss of left tackle Chad Clifton could be an issue. Barring such an injury setback, though, the Packers have three games that stand out as challenges unless they throw in an unforeseen clunker: They are in San Diego after a Green Bay off week and a pair against the undefeated Lions.
Interestingly, the finale at Lambeau against the Lions may be the most problematic. If the Pack has home field wrapped up by then, they may take the foot off the pedal against a division foe they may play in the postseason.
They showed vulnerability
A chance for the Packers to finish unbeaten? Yes.
The Falcons showed, at least for a little more than a half, that Green Bay can be slowed and held to field goals.
