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. And the Vikings have arguably played the tougher schedule.

But that's not how we operate. We do know history. We know that the Chiefs are the standard of the NFL and in the midst of a dynasty. And it's not like they've beaten a bunch of nobodies this season either. That's why the Chiefs take back the top spot in this week's rankings, even though the Vikings can claim the title of the best team thus far based solely on results.
