We have all experienced devastating Dallas Cowboys losses. Pick your favorite. Maybe the game that came to mind for you right away was when Dez caught it. Perhaps it was the Tony Romo bobble. You may be thinking about the 1994 NFC Championship Game. Odds are high that it was a playoff loss and we all are well aware that there have been many of those to choose from over the last 30 years (almost).
When you think about regular season losses they obviously do not hit the same, but the finales from 2011-2013 are up there.
