Folks have it a bit wrong.
If we beat AZ, we're the 2 seed and Atlanta is the 3 seed. So it's not like you just flip the game and have the Falcons play here.
So the questions are: does Atlanta beat the Cowboys, and do we beat the Packers ?
Honestly, I don't think we beat the Packers. They play us a lot closer, and Wilson just doesn't play well against them, home or away. With all our injuries, I think GB hangs 24-30 points on us, and we don't reciprocate.
Say we do face Atlanta at home this weekend. We'll get them here, with the weather which was cold and windy. Wilson typically doesn't play really well in the cold windy conditions in the playoffs either. I just don't think it was our year this year, with all the injuries and a really young OL that needs to grow.
Now, if our OL can grow next year to league average, Wilson gets his feet back under him (he had a poor year IMO), and we can reload the secondary (looking at the draft this will be easy to do) we're right back in it. This division is still ours for the taking.
