Three weeks are in the books. We have an exciting, three-team race in the AFC East.
Here's how things turned out in our latest ESPN.com Power Rankings:
New England Patriots (2-1)
Result: L, 34-31 vs. Buffalo
Power Ranking: No. 3 (down one spot)
Walker's vote: No. 3 (down two spots)
Analysis: The Patriots fell one spot after their upset loss to Buffalo. New England had control of the game early -- taking a 21-0 lead -- before quarterback Tom Brady threw four interceptions and the Patriots' defense fell apart. ESPN.com's panel still thinks highly of the Patriots, despite some issues with the defense. The chances of Brady throwing four interceptions in a game again are slim. So there shouldn't be any panic in New England.
Buffalo Bills (3-0)
Result: W, 34-31 vs. New England
Power Ranking: No. 6 (up 10 spots)
Walker's vote: No. 7 (up 10 spots)
Analysis: The Bills continue their meteoric rise in the Power Rankings. Buffalo climbed ten spots after beating New England. The Bills, the only undefeated team in the AFC, have climbed 21 spots the past two weeks. I don't think I've seen any team rise that fast in a short span. The Bills are hungry and they're a fun team to watch. Buffalo's next task is staying focused. The Bills have to guard against a potential letdown Sunday against the struggling Cincinnati Bengals (1-2).
New York Jets (2-1)
Result: L, 34-24 vs. Oakland
Power Ranking: No. 7 (down four spots)
Walker's vote: No. 8 (down four spots)
Analysis: Many people picked Oakland to upset New York, and they were right. The Jets had a poor West Coast trip. New York blew a 17-7 lead to Oakland. Whether it was a blip or a sign of things to come remains to be seen. The NFL schedule makers didn't do the Jets any favors. After traveling to Oakland, New York will travel to Baltimore and New England in back-to-back weeks. That could be major trouble for the Jets if they don't clean up their mistakes.
Miami Dolphins (0-3)
Result: L, 17-16 vs. Cleveland
Power Ranking: No. 29 (down four spots)
Walker's vote: No. 29 (down five spots)
Analysis: The Dolphins were banking on turning things around on the road. That was a dangerous assumption. Miami continued its poor execution in losing to the Browns. The Dolphins couldn't do much in the red zone and allowed the Browns to pull off a late, game-winning touchdown. Many expect the Dolphins to go in the tank with an 0-3 start and a coach now on the hot seat. Sunday's road game against the San Diego Chargers (2-1) will show whether Miami is willing to fight out of this slump.
