Is atl's home record really 18-1 or 18-2?

Unfortunately, one loss at home to the playoff bound Packers isn't going to change this sentiment.

It will change for the division at least. The Packers still have to play the Lions, Pats, Bears, and Giants so I doubt they'll be able to run the table. They barely beat the Lions 28-26 earlier in the season at home and have already lost to the Bears once this year.
