You're gonna have to ask me in about 2 years to get a TRUE answer. And here's why:
Before yesterday I would have told you the 07/08 giants at lambeau favre interception game, and I would have listed the Arizona non-facemask call thriller.
I would probably say the SB against denver as well but fortunately I was about 7, 8 years old at the time and didn't live and die by the packers (ah the joys of being an innocent child lol.)
IF in two years the packers never recover from this and don't make it to another NFC Championship game, or go one and done in the playoffs...or god forbid don't even make the playoffs... I will probably tell you this is the worst loss i've ever witnessed.
If the pack wins the SB next year it'll sting but it will sting much less, and I will probably tell you a different game...most likely the 07/08 NFCCG.
Asking me now of course i'd pick yesterdays game because it's so FRESH in my mind I can't help but feel my judgement is impaired. I've never felt more heartbroken over a game...but I was pretty devastated after that NFCCG against the giants and the overtime loss to Arizona for me personally is the angriest i've ever been due to the non-facemask which was blatant. So you'd have to ask me in a year or two to really know my answer.
