Week 4 saw an AFC East showdown that started out with the Bills and Dolphins trading blows, but ultimately saw the Bills remind the Dolphins who was boss.

Tough to see the Bills losing their stranglehold on the division if Josh Allen continues to play as well as he did against the Dolphins during Sunday’s 48-20 win.

Elsewhere, one of the best games of the week happened at the Meadowlands, with Taylor Swift once again watching her beau Travis Kelce.

The Chiefs sure seemed like a slam dunk against the Jets, but then stumbling, bumbling Zach Wilson morphed into a stud, showing off his titanic arm, and making plays all over the field.

Of course, Wilson wound up fumbling a snap, and losing the game late, but the Jets might not be toast without Aaron Rodgers after all.

The Patriots? They were crushed by the Cowboys, and at 1-3, losing by 35, may have hit bottom.

Here are the power rankings headed into Week 5:

1. 49ers (4-0): Who needs George Kittle and Deebo Samuel when you’ve got Christian McCaffrey and Brandon Aiyuk?

2. Eagles (4-0): They’ve been pushed, poked, prodded and pressed by opposing teams hellbent on beating them the first four weeks. And they haven’t blinked.

3. Bills (3-1): Allen & Co. simply reminded everyone they aren’t going to surrender the AFC East without a fight.

4. Chiefs (3-1): Is Swift a good luck charm? The Chiefs are 2-0 with her in the crowd, and needed every edge to take down the Jets on Sunday night.

5. Dolphins (3-1): The Bills served Mike McDaniel and the Dolphins a huge dose of humble pie, burying the team that’s been blowing everyone out.

6. Cowboys (3-1): They handed Bill Belichick the worst beat down of his coaching career. Enough said.

7. Ravens (3-1): Lamar Jackson almost single-handedly took down the Browns’ menacing defense.

8. Lions (3-1): They jumped into first in the NFC North by beating the Packers, and may never look back.

9. Seahawks (3-1): Are we witnessing a Legion of Boom redux? Monday night against the Giants, Pete Carroll’s defense had 11 sacks, three takeaways and two turnovers on downs.

10. Chargers (2-2): Hard to believe they would win with Justin Herbert completing just 13 passes and throwing a pick. But they did.

11. Rams (2-2): Cooper who? Puka Nacua’s legend continues to grow, as his overtime TD secured another win for the Rams.

12. Buccaneers (3-1): Surprise, surprise. They continue to win, and sit atop NFC South.

13. Packers (2-2): They can’t expect Jordan Love to dig them out of two-score deficits every week.

14. Jaguars (2-2): The UKs favorite sons played their best game of the season, dominating the Falcons early in the London opener.

15. Browns (2-2): Without Deshaun Watson, the Browns seem rather pedestrian.

16. Commanders (2-2): Love the resiliency of Sam Howell. After a forgettable performance the week before, he nearly pulled off an upset of the Eagles.

17. Colts (2-2): Anthony Richardson kept his team in the game with some second-half heroics, but still fell short.

18. Titans (2-2): Who knew the Titans had a 27-point game in their back pocket?

19. Jets (1-3): Wilson was on his way to being the unlikely hero. Then he fumbled a snap. And that was that.

20. Steelers (2-2): All of the offensive momentum they gained against the Raiders the previous game? It’s gone.

21. Saints (2-2): After being questionable with a shoulder injury, Derek Carr wound up playing. Given all the boos raining down in New Orleans, quite a few wish he didn’t.

22. Bengals (1-3): Is it time for the panic button? Joe Burrow still isn’t right.

23. Texans (2-2): Life with C.J. Stroud is off to a promising start. They took down the Steelers for the first time since 2011, and finally seem to have their answer at quarterback.

24. Falcons (2-2): After a hot start, the Falcons have come back to earth. Ditto Desmond Ridder.

25. Patriots (1-3): The Pats were awful across the board against the Cowboys. Coaching staff included.

26. Raiders (1-3): Hard for any quarterback to win, much less a rookie making his first start, if he’s running for his life. Aidan O’Connell was sacked seven times in his debut.

27. Cardinals (1-3): They’re better than their record suggests, and better than what most imagined. They’ve been in every game.

28. Vikings (1-3): The Vikes appeared headed for 0-4, but saved themselves some embarrassment after waking up in the second half.

29. Giants (1-3): The offensive line is a disaster.

30. Broncos (1-3): The best thing you can say is they won despite their woeful defense, which has given up 98 points the last two weeks.

31. Panthers (0-4): Given how underwhelming Bryce Young has looked, you have to wonder when, or if, the Panthers will win a game this season.

32. Bears (0-4): Justin Fields had a career day against a pathetic Broncos defense. The problem. Their defense was just as pathetic, unable to hold a 21-point lead.
