When the Minnesota Vikings beat the San Francisco 49ers, it was a nice upset. Then the Vikings beat the Houston Texans, and it grew into a cool early-season story.
After Week 4, 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 NFL 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. The Vikings led the Green Bay Packers 28-0 in the first half and while the Packers rallied in the fourth quarter Minnesota was so dominant though three quarters that it didn't matter.
