Lol, I have to laugh when I hear a 49er fan tell me they're fine with the regular season win streak and don't care about the one loss because it shows dominance. I know they are not fine with it.
I got to believe the 2021 NFC Championship Game loss to the Rams
has to haunt many 49ers' fans.
I can't speak for any other die-hard sports' fans but as a 50-plus-year Rams' die-hard, for me, the most painful losses (aside from the Super Bowls) were the two NFC Championship Game losses in Minnesota all the way back in 1974 and 1976.
And the reasons are the same. The Rams were as good or better than the Vikings those seasons; AND, in my opinion, the Rams were the better team those two days but lost heart-breaking games that denied them a Super Bowl appearance.
The Rams have lost other huge playoff games in my half century of fandom
(FUCK! I am old!).
Their record in NFC Championship Games, prior to the Greatest Show on Turf in 1999, was an awful
1-6.
I remember them all very well; and the Rams had some excellent teams those seasons. However, the other four losses (excluding the MN games in '74 and '76) were to teams that were Much Better that specific day.
I can ... and have ... accepted that.
But those two losses to the Vikings haunt me.
No complaints though, I have many great memories of terrific post-season victories. A few of which were games where the Rams may not have been the better team even on that particular day. Things do balance out ...
if you live to be an old-fart like me.
By-the-way, the Rams are 4-0 in NFC Championship Games since 1999!
