Different week, new team at the top.
That's how it's went for four straight weeks in our Quality Stats Power Rankings.
Actually, the last four editions (dating back to 2011's final standings) of the CHFF Quality Stats Power Rankings have seen the previous week's No. 2 team overtake the top spot.
Right now, it seems the Texans and Falcons have joint custody of the No. 1 spot. Houston had it heading into Week 3, only to cough it up to Atlanta and drop to No. 2.
Now, Houston has hopped into first once again, with the Falcons back at No. 2. If the trend continues, Atlanta will be right back on top next week.
Here are the biggest movers (and non-movers) after Week 4.
Moving Up: Denver Broncos (+13), San Francisco 49ers (+10)
Standing Still: Miami Dolphins (No. 20), Indianapolis Colts (No.27), Kansas City Chiefs (No. 32)
Moving Down: New York Jets (-16), Dallas Cowboys (-14), Buffalo Bills (-10)
1. Houston Texans (4-0) - There's simply nothing to pick at with a team that ranks in the top five of all but one Quality Stat (No. 1 or No. 2 in five of them) and is outscoring opponents by 17 points a game. Kudos to you, Houston.
2. Atlanta Falcons (4-0) - Atlanta pulls out a 30-28 thriller in the Georgia Dome, but loses their hold on the top spot. Nonetheless, Matt Ryan (for MVP?) and the offense continue to lead the NFL in Offensive Passer Rating.
3. Baltimore Ravens (3-1) - Thursday night's 23-16 win over the hapless Browns saw the Ravens accomplish enough on defense to squeeze into the top five in both Bendability and the all-important Passer Rating Differential.
4. Arizona Cardinals (4-0) - The Cardinals are still undefeated? You bet. Don't credit the O-line, though, which now ranks dead last in our Offensive Hog Index. The defense's unique ability to bend but not break (No. 1 in Bendability) is the reason they're winning these close games.
5. Chicago Bears (3-1) - Da Bears are absolutely rolling on D, having picked off Tony Romo five times Monday night (two returned for touchdowns). Chicago is No. 1 in Defensive Hog Index and No. 2 in Passer Rating Differential.
6a. New England Patriots (2-2) - The Pats are locked in a tie for No. 6, sliding up six places after dropping 52 points on the Bills in Week 4. The bad news: New England is 0-2 against Quality Opponents.
6b. San Francisco 49ers (3-1) - There's nothing quite like a 34-0 thrashing of Mark Sanchez and the Jets to set you straight in the Power Rankings. The Niners dominating performance on D moved them up nine spots to No. 2 in Defensive Real Passing Yards per Attempt, and they even cracked the top five (No. 4) in Passer Rating Differential.
8. Minnesota Vikings (3-1) - The Vikings knocked off the lowly Lions to keep pace with the Bears atop the NFC North. Minnesota is powered by a defense allowing just 18 points per game.
9. Denver Broncos (2-2) - Denver dropped 27 on the defensively inept Raiders in the second half Sunday, turning a close game into a 37-6 rout. The Broncos piled up over 500 yards of offense and converted 10 of their 16 third down attempts.
10. Green Bay Packers (2-2) - After losing just one home game in two years, the Pack nearly lost their second in three tries but squeaked by the win-less Saints 28-27 to avoid an unimaginable 1-3 start.
11. New York Giants (3-1) - The Giants' 19-17 loss to the Eagles didn't just knock them from the top five, but out of the top 10, too. New York's inefficient day on offense vaused a fall from No. 11 down to No. 19 in Scoreability.
12. Philadelphia Eagles (3-1) - Philly's D has been lights out, but the offense can't find the end zone. The Eagles are averaging a measly 16.5 PPG and are No. 32 in Scoreability.
13. San Diego Chargers (3-1) - San Diego capitalized on six Kansas City turnovers to slide up 16 spots in Scoreability (No. 5) and take control of the AFC West.
14. Seattle Seahawks (2-2) - Down goes Seattle. The Hawks' road woes continued in St. Louis and they drop seven spots after coughing up a divisional game to the Rams on Sunday.
15. St. Louis Rams (2-2) - Speaking of those pesky Rams, the No. 1 squad in Defensive Passer Rating has matched its win total from all of 2011 at the quarter mark of the season and they'll host the 4-0 Cardinals on Thursday Night Football in a prime-time divisional battle. Upset special?
16. Washington Redskins (2-2) - Robert Griffin III orchestrated a game-winning drive to down the Bucs in Week 4, and the Redskins move into the top half of the rankings as a result. Washington is No. 5 in Offensive Passer Rating.
17a. Pittsburgh Steelers (1-2) - Pittsburgh drops two spots despite being idle in Week 4. The Steelers are No. 29 in Bendability after finishing third in the Quality Stat for all of 2011.
17b. Cincinnati Bengals (3-1) - The Bengals are off to a great start, although it isn't showing in the rankings. Upcoming games against Miami and Cleveland should help in that regard.
17c. Buffalo Bills (2-2) - The third team in an unusual three-way tie for the 17th spot, Buffalo is also locked in a three-way tie for the AFC East lead with the Jets and Patriots. The Bills need to see more production from the defensive front (No. 26 in Defensive Hog Index), particularly from the under-performing DE Mario Williams.
20. Miami Dolphins (1-3) - Fresh off of two straight overtime losses, the Dolphins are dreaming of what life would be like at 3-1 instead of 1-3. Miami's eight-sack performance Sunday did boost them No. 10 to No. 2 in Defensive Hog Index. So, here's to building on that.
21. Carolina Panthers (1-3) - Cam Newton's big day wasn't enough to knock off the Falcons, but it help move the Panthers from No. 23 to No. 15 in Offensive Passer Rating.
22. Tampa Bay Buccaneers (1-3) - Each of the Bucs four games this season have been decided by a touchdown or less. Unfortunately, they were on the losing side in three of them.
23. Dallas Cowboys (2-2) - The 34-18 loss to the Bears send Dallas into free fall, moving all the way from No. 9 in the rankings, to No. 23. The Cowboys need to get DeMarco Murray and the run game patched up so Romo doesn't feel so much pressure to produce through the air. Hey, just an idea.
24. Detroit Lions (1-3) - It's tough to believe that it was the offense, not the defense, holding the Lions back on Sunday. Well, that and the atrocious coverage in special teams.
25. New Orleans Saints (0-4) - The Saints have allowed 32.5 PPG over their win-less start, and this Drew Brees-led offense just can't keep up.
26. Cleveland Browns (0-4) - Bad QB play has all but doomed the Browns once again. They're right back where they were last year (No. 30) in Real Passing Yards per Attempt and are at the bottom of the barrel in Real Quarterback Rating and Offensive Passer Rating.
27. Indianapolis Colts (1-2) - Indy was idle in Week 4, and they stayed put in the rankings, too.
28. New York Jets (2-2) - The Jets' giant drop in the rankings (16) is the largest one-week slide we've seen this year. That'll happen when you lose 34-0 and manage a measly 145 yards on offense.
29. Jacksonville Jaguars (1-3) - The Jags are 0-3 against Quality Opponents and rank dead last in Real Passing Yards per Attempt.
30. Tennessee Titans (1-3) - Tennessee's three losses have been by margins of 21, 24 and 28 points. The one victory? An overtime thriller over the 1-3 Lions in a game that neither team seemed to want to win.
31. Oakland Raiders (1-3) - The Raiders were just stomped by Denver and head to Atlanta this week. The Falcons are No. 1 in Offensive Passer Rating and Oakland is No. 30 in Defensive Passer Rating. Good luck with that.
32. Kansas City Chiefs (1-3) - The Chiefs haven't ranked higher than 30th all year. Probably a good indicator that they'll be down here awhile.
