45 years of fan memories is impressive. But it also skips the 45 years before that. And there has been somewhere between 42 and 46 NFC Championship games. Really small sample size.
As for the 12 of 17, a survey immediately after the game is a terrible way to put a loss into perspective.
But, in terms of the article, the rank of terribleness in this loss is immaterial to the main point. Rodgers poor play is indicative of several things. Its not indicative that he needs to be an even bigger part of the team.
