As a wonderful mix of pride and euphoria swirled through the Vikings locker room Sunday evening, a quest for explanations began.
In so many ways, the scene made so little sense. The NFL's most surprising team of 2012 had won the right to keep playing into 2013, upsetting the rival Green Bay Packers 37-34 on a last-second, 29-yard field goal by Blair Walsh.
That provided the climax to a wildly entertaining, often confusing and incredibly stressful day in which the Vikings never trailed but never felt completely safe either.
Walsh's kick triggered fireworks, then provided an even more notable locker room eruption at Mall of America Field.
Somehow, these Vikings are one of 12 teams left with a chance to win the Super Bowl.
"How about those Vikings, huh?" coach Leslie Frazier said with a double fist pump.
Sunday's triumph -- more improbable in its form than in its result -- provided the Vikings a 10th victory and created a playoff rematch with the NFC North champion Packers on Saturday night at Lambeau Field.
So it was worth asking: How in the world did all this happen?
