Not to burst anyone's bubbles, but post 2010, Rodgers and the Packers never really looked like world beaters when the playoffs rolled around.
That's over simplified. In some of our playoff wins we did, in some we didn't. 2010s NFC championship game was a knife fight that neither team looked like a world beater. Same with the loss in 2021 against the 49ers.
There is something to be said about playing up or down to the level of your opponent.
Playing up to the level of your opponent is a good thing, it implies you're not as good on paper but you rose to the occasion. Playing down to your opponent is something you need to not do.
Trouncing the Bears was a good thing. What happened against the Falcons is not, though I don't think there was playing down or up there. They played 3 quarters of good enough, complementary football on both sides of the ball. 12 point lead with 15 minutes to go is winning football, (mostly) irrespective of the other stats. And both phases failed to help out the other for the entire 4th.
Yes, the defense could have gotten another stop, but the offense could have also put together a good drive and taken away one of Atlanta's score by not giving them the ball.
