When the Minnesota Vikings beat the San Francisco 49ers in Week 2, it was a nice upset. Then the Vikings beat the Houston Texans the following week, and it grew into a cool early season story.
Now there's no mistaking what is happening with the Vikings anymore. They're not just one of the best teams in the NFL, they might be the best team in the league based on the early returns.
If there was any wonder about the Vikings' standing in the NFL's hierarchy after a 3-0 start, they erased it after what happened at Lambeau Field.
