NFL Power Rankings, Week 4: 49ers claim first place! Raiders and Vikings enter top 10; Patriots fall to 31 | Latest NFL News, Analysis and Updates

It took three weeks, but the NFL finally delivered on its promises on Sunday.

What a week it was. Twelve of the 16 games ended with a one-score difference, and although the opening and closing prime-time windows produced lopsided results, the chaos of Sunday’s witching hour more than made up for it.

The reigning champions are no longer undefeated. The entire AFC North is 2-1, while the entire NFC South is below .500. Five teams remain perfect at 3-0, including the Raiders (yes, those Raiders).

All of this calls for a big shake-up of the league hierarchy. Let’s see where everyone stands after three weeks of football.
