Last week's rankings in parentheses.
1. Rams 4-0 (1): Wide receivers Brandin Cooks, Cooper Kupp and Robert Woods are all averaging more than 80 yards per game and then there is running back Todd Gurley. It's a machine.
2. Chiefs 4-0 (2): Patrick Mahomes used his left hand to complete a pass to Tyreek Hill on the game-winning drive, but he beat the Broncos with his right arm and legs against a top-notch pass rush.
3. Saints 3-1 (3): Running back Mark Ingram returns from a four-game suspension and should give the offense a boost.
4. Titans 3-1 (13): Wide receiver Corey Davis, the fifth pick in the 2017 draft, is beginning to emerge. He had nine catches for 161 yards in a win over the Eagles.
5. Jaguars 3-1 (6): The Jags need to find a way to win without Leonard Fournette for a while after running back reinjured his hamstring. The defense faces a challenge in Kansas City.
6. Patriots 2-2 (12): Josh Gordon debuted in the offense in a blowout win over the Dolphins and Julian Edelman returns from suspension this week, so things are looking up in New England.
7. Ravens 3-1 (14): Marlon Humphrey, their first-round pick a year ago, is turning into a really good player and the cornerback did a commendable job on Steelers star Antonio Brown on Sunday night.
8. Eagles 2-2 (4): They host the Vikings in a rematch of the NFC championship game. Neither team is playing at the level it was last year. The Eagles have scored only seven points in the first quarter.
9. Bengals 3-1 (17): Andy Dalton led a 16-play drive to win 37-36 in Atlanta on a 13-yard pass to A.J. Green with seven seconds remaining and the Bengals are playing with a lot of emotion.
10. Bears 3-1 (15): Mitch Trubisky's six touchdown passes and an offense with a wide array of skill-position players have given fans plenty to talk about after the defense carried the first two victories.
11. Packers 2-1-1 (16): The defense shut out the Bills, but QB Aaron Rodgers called the offense "terrible" and "not acceptable" following a 22-0 victory. Dropped passes have been an issue.
12. Dolphins 3-1 (5): Which was an aberration: the 3-0 start or the no-show performance in New England? We'll find out when the Dolphins visit Cincinnati to face a Bengals team that is playing well.
13. Panthers 2-1 (10): Right guard Trai Turner has been cleared from concussion protocol, which is good news for an offensive line still missing the starting left and right tackles.
14. Chargers 2-2 (18): Kicker Caleb Sturgis has missed two field-goal tries and three extra points, and that's a concern for a team that employed five players on field goals, extra points and kickoffs last season.
15. Steelers 1-2-1 (7): Running back Le'Veon Bell will reportedly show up for work during the Week 7 open date. That means two more games without the main cog in the offense starting with Sunday's visit from the Falcons.
16. Broncos 2-2 (19): The defense did a nice job corralling Patrick Mahomes for three quarters Monday night but couldn't finish off the Chiefs.
17. Vikings 1-2-1 (11): Questions about the previously vaunted Vikings defense are piling up for coach Mike Zimmer.
18. Falcons 1-3 (9): Atlanta was 11-for-15 on third down and did not have a turnover and still managed to fall 37-36 at home to the Bengals. That's mind-boggling.
19. Redskins 2-1 (20): A Monday night date in New Orleans begins the toughest stretch of schedule for the Redskins, who at least are rested after a week off.
20. Cowboys 2-2 (23): So much for putting together a trade for Seahawks safety Earl Thomas.
21. Buccaneers 2-2 (8): Legend has it when former Bucs coach John McKay was asked about his team's execution, he replied, "I'm in favor of it." Current Bucs coach Dirk Koetter can relate.
22. Seahawks 2-2 (28): Earl Thomas wasn't saluting the organization he has spent his entire career with when he was carted off with a broken leg Sunday. He was bidding goodbye with his middle finger.
23. Giants 1-3 (24): Coach Pat Shurmur admits he probably should have given running back Saquon Barkley more than 16 touches in a loss to the Saints. Through four weeks, Barkley has 56 carries, tied for ninth in the league.
24. Lions 1-3 (22): A defense that struggled mightily rushing the passer a year ago is improved as the Lions have 13 sacks, tied for fourth in the league. The new problem? The Lions are 32nd against the run.
25. Browns 1-2-1 (21): When you have a 14-point lead in the third quarter, end up scoring 42 points and you still lose, you're the Browns.
26. Texans 1-3 (30): After getting a gift from the Colts in overtime, the Texans have to beat the Cowboys on Sunday to get their season back on track.
27. Jets 1-3 (26): Pressure is building on coach Todd Bowles amid a three-game losing streak, and that's life in the NFL, even if you're playing a rookie quarterback.
28. Raiders 1-3 (32): They rolled up 565 yards offense in Jon Gruden's first victory, the fourth-most in franchise history.
29. Colts 1-3 (27): The gambler Frank Reich _ he went for it on fourth-and-4 from his own 43-yard line in overtime _ says he'd do it 10 times out of 10. It didn't work against the Texans, and now it's on to New England.
30. 49ers 1-3 (29): They could be without three starting offensive linemen for Sunday's meeting with the Cardinals.
31. Bills 1-3 (25): Kelvin Benjamin was critical of the Panthers after they traded him to the Bills last year. Now he's openly questioning his new team's meager passing game, the worst in the NFL.
32. Cardinals 0-4 (31): Josh Rosen actually looked pretty good in his first career start, but he didn't get help from the Cardinals receivers, who dropped five passes.
