The Cowboys MNF game is most memorable for me - despite the outcome. The electricity was palpable hours before kickoff. It was a gorgeous night, beautiful sunset and such a party atmosphere all around the stadium grounds pregame. Inside it was incredibly intense the entire game.
The only other time I can remember feeling that kind of electricity before a game was in 74 or 75 when the Braves hosted a playoff game against the Celtics. It was electric In the Aud. Braves lost as well, thanks to refs and Jo Jo White
