Whose 4-0 start has been more impressive? When it comes to the Broncos and Seahawks, our voters (John Clayton, Ashley Fox, Dan Graziano, Jamison Hensley, Mike Sando and Kevin Seifert) choose the former.

Buoyed by four first-place votes, Peyton Manning & Co. have gained the No. 1 spot for the first time this season. Seattle falls to No. 2, ahead of the unbeaten Saints, Patriots and Chiefs.

Even though the Seahawks beat a 2012 playoff team (Houston) on the road in Week 4, the Broncos' season-long dominance is ringing more loudly. After a 52-20 pasting of Philadelphia, Denver is now averaging an amazing 44.8 points per game with a 22-point average margin of victory.

Does that mean the Broncos' reign is built to last? Most of the signs say yes, but the schedule will soon get tougher. Seattle likely isn't going anywhere, either. Right now, though, it just doesn't have the style points to stay on top.
