If you paid attention to only results of four games and not past history, like a few shiny Lombardi Trophies, there isn't much doubt the Minnesota Vikings have been the best team in the NFL this season.
The Vikings are 4-0 with three impressive wins over some of the best teams in the NFL. They've made the 49ers, Texans and Packers look bad. Minnesota has played well in every phase, Sam Darnold looks like a potential MVP candidate and their point differential of +57 is almost triple that of the Kansas City Chiefs, the other 4-0 team that is +20.
