69-70s postseasons were always brutal.
Mostly, Yes. This 1973 Divisional Round loss in Dallas was really tough. The '74 and '76 NFCCG losses in MN were absolutely brutal. All because they were incredibly close and the Rams Could-A / Should-A won them.
The 1975 and 1978 home NFCCG defeats to the Cowboys were tremendously disappointing because the Rams played like shit.
The '77 loss was explainable ... some Vikings' fans sold their worthless Souls to the Devil.
However, the 1976 and 1979 wins in Dallas were Fantastic and Great Memories. Dallas' fans Would / Should feel the same way about those losses as Rams' fans felt about this 1973 game.
I would feel a little sorry for them (Cowboys' fans) but they are mostly ass-holes.
