To me after 1964 this is the worst. That was long before me though. That being written, I dont feel nearly as much pain inside after what happened in Super Bowl 39. I legit couldnt eat correctly for 3 months until Liverpool beat AC Milan.I remember 1977 was bad but I don’t remember the details at this point. But more disappointing than this for sure. 2002 against TB is maybe the worst one that I remember clearly. But the all-time worst for me, even though I have only very vague memories of it (probably my earliest semi-clear sports memory) is 1964. I’ve never gotten over that and I’ve hated the Cardinals for it to this day.
