Yeah, of course they can walk into Minnesota and win - they did just that last new year's eve and embarrassed the Vikings in their building when both teams had to get a W to think about making the playoffs.
Last year's Packer younger and less experienced team got on a late season roll, embarrassed the 2 seed Cowboys (who were also rolling and had been pounding teams at home) in round 1, and frankly should have beaten the 49ers on the road the following week in the divisional round.
All I'm saying is with how the NFC playoff field is shaping up, none of the teams hosting any playoff games would want to face a potential 13-win wild card Packers team that appears to be peaking and healthy, when their only 4 losses were coin flip 1 possession games came against the best teams in their conference with the exception of that 2 possession loss in the rain against the Lions months ago.
worrying about a potential playoff draw that includes a bunch of good teams doesn't make much sense to me, when I don't think there's a team on paper that is undoubtedly better than the Packers (exception maybe being the Eagles at this point with a healthy Hurts) - with only 1 team getting a bye and that likely coming down to either an injured Lions squad or an overrated Vikings team, to me that's just 1 less week for either of those teams to get exposed by a quality playoff opponent.
