The Bengals' 31-24 upset win over the Packers at Lambeau Field really shook up the rankings, as Cincinnati jumped from 25th to 13th in front of Green Bay.
Then Pittsburgh lost to Chicago, dropping the top-ranked Steelers all the way down to 16th, behind the Bears, who lost to the Packers in Week 1.
The big winner in all this was 2-0 Denver, which leaped from 24th to 12th, thanks to its miracle victory over Cincy in Week 1.
1. Baltimore Ravens (2-0)
Baltimore's impressive 31-26 win at San Diego, combined with Pittsburgh's loss, leaves the Ravens atop the rankings this week. Baltimore has the best rushing defense (41 yards per game) and fourth-best rushing offense (164 ypg).
2. New York Giants (2-0)
3. Indianapolis Colts (2-0)
Against Miami, Indy had the ball for only 14:53, the lowest time of possession for a victorious squad in 32 years.
4. Minnesota Vikings (2-0)
The Vikes have opened the season with two road wins, albeit over Cleveland and Detroit.
5. New Orleans Saints (2-0)
Scoring 45 on Detroit is one thing, but putting up 48 at Philly is another. The Saints have the best offense (468 ypg) in the league.
6. Atlanta Falcons (2-0)
You think Matt Ryan likes having Tony Gonzalez on his team? The two hooked up for more than 70 yards and a score for the second straight week.
7. San Diego Chargers (1-1)
Even without LaDainian Tomlinson, the Bolts hung tough with a strong Ravens team. It was a far better performance than their game against Oakland in Week 1, even though they won that contest.
8. Dallas Cowboys (1-1)
Did anyone else catch those "Cage Girls" dancing above the cheap seats at the new Cowboys Stadium? Bravo, Jerry Jones.
9. New York Jets (2-0)
I guess those seven points the Jets allowed the Texans in Week 1 was no fluke, especially since Houston went out and scored 34 on Tennessee. Rex Ryan has the best defense in the NFL (241 ypg).
10. New England Patriots (1-1)
Not sure how some people had the Patriots among the top two in their power rankings last week after they barely snuck by the Bills, which those same people had ranked some 20 spots lower.
11. Philadelphia Eagles (1-1)
There's no shame in losing to the Saints when you don't even have Donovan McNabb available, but McNabb doesn't play defense and giving up 48 at home is never a good thing.
12. Denver Broncos (2-0)
I think this is the biggest surprise so far this season. The seven points the Broncos held the Bengals to in Week 1 is looking a lot more impressive after Cincinnati scored 31 at Green Bay on Sunday. Denver has the second-best defense in the league (253.5 ypg).
13. Cincinnati Bengals (1-1)
A lot of knockout pool participants were cringing at around 4 p.m. on Sunday.
14. Green Bay Packers (1-1)
Aaron Rodgers has been sacked 10 times in two games: more than any other quarterback in the league.
15. Chicago Bears (1-1)
After a 43.2 QB rating at Green Bay in Week 1, Jay Cutler turned in a 104.7 performance at home against the Steelers.
16. Pittsburgh Steelers (1-1)
A loss to Chicago, combined with the fact that their Week 1 win over Tennessee doesn't look as good anymore, drops the Steelers 15 spots.
17. San Francisco 49ers (2-0)
Since Week 13 of last year, the Niners have won six games. By comparison, the Patriots have won just five.
18. Buffalo Bills (1-1)
The Bills have the sixth-best rushing attack in the NFL (154 ypg).
19. Arizona Cardinals (1-1)
Kurt Warner's record-breaking 24-for-26 performance led the Cards to a nice bounce back win at Jacksonville, despite the east coast 1 p.m. start for a West Coast team.
20. Houston Texans (1-1)
After a disappointing home-opening loss to the Jets during which they scored just seven points, the Texans put up 34 at Tennessee.
21. Tennessee Titans (0-2)
The Titans have the second-best rush defense in the league (49.5 ypg) but the worst pass defense (339 ypg).
22. Seattle Seahawks (1-1)
Seahawks fans could be looking at a repeat of 2008 if Matt Hasselbeck isn't able to recover quickly from a rib injury he suffered against San Francisco.
23. Carolina Panthers (0-2)
At least Jake Delhomme only threw one interception this game.
24. Miami Dolphins (0-2)
I feel a little better about taking Ronnie Brown over Brian Westbrook in my fantasy draft now.
25. Washington Redskins (1-1)
I don't care if they win, scoring only nine points on the Rams will get you dropped three spots in my rankings.
26. Jacksonville Jaguars (0-2)
The Jags are 5-14 since beating the Steelers in the 2007 wild card playoffs.
27. Oakland Raiders (1-1)
The Raiders beat the Chiefs despite only having 176 yards of offense and holding the ball for just 21:21.
28. Tampa Bay Bucs (0-2)
The Bucs have the second-worst defense in the league (450 ypg).
29. Cleveland Browns (0-2)
Disappointing start for the Eric Mangini era in Cleveland.
30. Kansas City Chiefs (0-2)
Even with Matt Cassel back, the Chiefs can't win.
31. St. Louis Rams (0-2)
Fifty-eight players have scored more points than the Rams this year, including Olindo Mare and Shayne Graham.
32. Detroit Lions (0-2)
Even Ernie Harwell couldn't get the Lions a win.
