No. My comment coincides similarly with the OP's tweet. There is zero relevancy for NFC championship games outside the tweet's timeframe prior to 2016.
If any member wishes to change the parameters of the OP for further discussion, I highly recommend pro-football-reference.com (or sports-reference.com and select Football instead). It provides detailed information for researching post-1970 regular season NFC Championship games through the present. However, I do believe that is irrelevant to the intended purpose of this thread, which is, again, stated in the OP's tweet.
