I don't think i can say Atlanta got Chicago luck. They would have needed to lose by some BS penalties like we did against them on Monday Night last year, or lose by a really stupid call (Lions in week 1 last season)
Look at their schedule from last year, and compare how we just slaughtered them in the playoffs.
They are NOT that great of a team when challenged by an equal or better team.
Last year they lost to Pittsburgh, Philadelphia, and New Orleans (almost got swept had Hartley not missed a 30 yard field goal in OT). Then we just BURNED them down.
They beat Baltimore last year, and that was the only plus they got from a very weak schedule. Seriously, those 4 teams and Tampa bay as a divisional was the hardest games they had last year.
The schedule they have this year, they won't be winning 10 games.
