NFL Power Rankings: Week 7

Unbeaten at 6-0 and holding the top spot, the 49ers are carried by one of the league's best offenses against a middling defense that has still been enough to win every game so far.

A perfect 5-0 record puts Kansas City near the top of the league, backed by a top-eight offense and an above-average defense. The Chiefs have outscored opponents 140 to 83 this season, winning their last outing over the Chargers 22-6.

Sitting third overall at 5-1, the Bills carry one of the league's best offenses — though a below-average defense keeps them from climbing higher.

A top-eight defense has held opponents to 125 points while carrying a middling offense — the Broncos sit 4-2 but have scored just 114 points themselves, a gap that will be tested on the road against Arizona in Week 7.

A 2-4 record undersells a team that carries both a top-eight offense and a top-eight defense, and the season scoring totals are nearly dead even — the standing looks worse than the underlying strength.

A 26-19 win over the Jets keeps New England at 4-2 and holding steady at the same spot in the rankings. An above-average offense and a middling defense describe a team without a glaring weakness or a standout edge — they head to Chicago in Week 7 to face the Bears.

One of the league's best defenses is carrying one of the league's weakest offenses to a perfect 5-0 start — Minnesota has allowed just 64 points while scoring 109. The Colts come to town in Week 7.

Up eight spots to sit at No. 10, Houston's rise is driven by one of the league's best defenses — the unit has held opponents to 143 points while the offense, middling by nature, has managed just 144 points for at 2-4.

A 23-13 win over the Cowboys moved them up three spots to 11th, and at 4-2 the Packers look like a quietly solid team with an above-average offense and a middling defense. They head to Detroit in Week 7 for a divisional road test that will say a lot about where they actually stand.

A road win over Atlanta keeps the Bears at 4-2 and holding steady in the rankings. An above-average offense and a middling defense host New England at home in Week 7.

Jumped 12 spots on the back of a 4-2 record built almost entirely by a top-eight defense — most recently a 13-10 win over Baltimore. The offense remains one of the league's weakest, so the margin for error stays razor thin heading to Tennessee in Week 7.

Dropped six spots to 14th after a loss to the Browns left them at 4-2, with a middling defense allowing 132 points already this season doing most of the damage.

A 25-14 road win over the Eagles keeps Carolina at 3-2 and holding steady at 15th. The Buccaneers come to town in Week 7, a winnable home date for a team with an above-average offense and a below-average defense that has been balanced enough to stay afloat.

Dropped 7 spots to 16th, the Lions carry one of the league's best offenses but a below-average defense has allowed 148 points — the clearest drag on their standing at 3-2.

A 26-19 road win over the Buccaneers keeps Pittsburgh at 4-2, with an above-average defense doing the heavy lifting for a below-average offense. They head to New Orleans in Week 7 for a game that should stay close.

A top-eight offense paired with one of the league's weakest defenses has produced a lopsided 2-4 Cowboys squad — 151 points scored against 159 allowed tells the story. They dropped 3 spots this week and head to Philadelphia next.

Lost to the Titans at home last week, falling 3 spots to 20th in these rankings with a 2-4 record. A middling offense and a below-average defense head to Minnesota in Week 7.

A 23-31 home loss to the Bears dropped Atlanta a spot to 21st, and the offense — already below average on the season — will need to find consistency against the 49ers in Week 7.

A home loss to the Saints — allowing 34 points with a below-average defense and a middling offense — drops them two spots to 23rd. At 3-2-1, they head to Houston in Week 7 with little margin for drift.

A narrow road win over the Rams — 18-16 — pushed Arizona up three spots to 24th, and the Cards sit at 2-4 with a middling offense and a below-average defense. The Denver Broncos come to town in Week 7.

One of the league's weakest offenses is dragging down an above-average defense, leaving Philadelphia at 2-4 after dropping three spots this week. The Eagles lost at home to the Panthers, 14-25, and host the Cowboys in Week 7.

A 34-27 road win over the Giants has the Saints up three spots despite a 2-4 record, and nothing about this team screams danger — below-average offense, middling defense. The Steelers come to New Orleans in Week 7.

Dropped four spots to 28th after a home loss to the Steelers left them at 1-5, with a below-average offense that has managed just 119 points for the season dragging the team down despite an above-average defense.

A loss to the Patriots dropped them a spot to 29th with a 2-4 record, both sides of the ball sitting below average. The Dolphins come to town in Week 7.

At 0-6, the Chargers carry one of the league's weakest offenses into a season that has produced only 90 points — while even a top-eight defense has not been enough to compensate.

Winless at 0-5, the Dolphins have been sunk by a below-average offense paired with one of the league's weakest defenses — a combination that has them allowing 132 points while scoring just 70 through five games.

At 1-5, the Titans own one of the league's weakest offenses and one of the league's weakest defenses — a combination that explains the 84 points scored against 129 allowed. They held steady at the bottom of these rankings after a narrow win over the Colts.
