The Broncos maintain an unblemished record and their hold on the No. 1 spot in this week's ESPN NFL Power Rankings. Convincing Week 4 victories by Seattle and Pittsburgh pushed ESPN's power panel (a group of more than 80 writers, editors and TV personalities) to move both teams up to No. 2 and No. 3, respectively.

Check out the rest of the league and where each team ranks.

Previous rankings: Week 4 | Week 3 | Week 2 | Week 1 | Preseason

ESPN Stats & Information contributed the following information, which this week focuses on the numbers to know for each team.

2016 record: 4-0

Week 4 ranking: No. 1

38.4: You can run but you really can't hide from this Broncos pass rush. Denver has pressured opposing quarterbacks on a league-best 38.4 percent of dropbacks. Next highest? 32.3 percent (Bills).

2016 record: 3-1

Week 4 ranking: No. 3

20: The Seahawks have played four games this season and in each game, their opponents have failed to score 20 points. If this pace keeps up, Seattle could allow the fewest points for the fifth consecutive season.

2016 record: 3-1

Week 4 ranking: No. 9

30: The Steelers' offense wanted to average 30 points per game this season, and a 43-point effort in Week 4 will help erase the three-point effort from the week before. The Steelers are currently averaging 27 points per game.

2016 record: 3-1

Week 4 ranking: No. 2

12: If Tom Brady, who dons No. 12, had an entrance song, it'd be time to cue his music. The Patriots are 3-1 as Brady returns to their lineup and the rest of the league is on notice. The Patriots have a .771 winning percentage under Brady since 2001.

2016 record: 4-0

Week 4 ranking: No. 4

+10: The Vikings are 4-0 for the first time since 2009, and they are doing it behind a combo of solid offense and defense. The Vikings have committed one turnover with 11 takeaways, good for an NFL-best plus-10 turnover differential.

2016 record: 2-1

Week 4 ranking: No. 6

1.8: So much of the talk surrounding the Packers revolves around QB Aaron Rodgers or the offense, but has anyone noticed what the defense has been doing? Specifically, the 1.8 yards per rush allowed so far? Every other team is allowing at least 3.1 yards per rush.

2016 record: 3-0

Week 4 ranking: No. 7

27: Rookie QB Carson Wentz has been great, but don't forget the defense in Philadelphia, which has allowed 27 points in three games. The last Eagles team to allow that few points in the first three games was the 1992 squad that went 11-5.

2016 record: 3-1

Week 4 ranking: No. 18

152: The Falcons have scored at least 35 points in three straight games and have now scored 152 points on the season. The 2013 Broncos, 2002 Raiders and 2000 Rams are the only teams in the past 20 years to score that many points in the first four games of the season.

2016 record: 3-1

Week 4 ranking: No. 14

2002: The Raiders sit 3-1 through four games and you can't blame Raider Nation for being excited. The Raiders haven't been 3-1 or better through four games since the 2002 season, which also happens to be their last Super Bowl appearance.

2016 record: 2-2

Week 4 ranking: No. 13

468: A.J. Green is somehow getting better. He has caught 76 percent of his targets this season and his 32 receptions and 468 receiving yards are his most through four games. He does have two drops though, so he is technically human.

2016 record: 3-1

Week 4 ranking: No. 11

131: It might be time to start believing the hype on Dak Prescott. We've all heard he hasn't thrown an interception this season, but according to Elias Sports Bureau, his 131 attempts are tied with Warren Moon for second-most without a pick to start a career and trail only Tom Brady (162).

2016 record: 2-2

Week 4 ranking: No. 15

5: Odell Beckham Jr. hasn't found the end zone since Dec. 20, 2015. That's five straight games played for Beckham without a touchdown, the longest streak of his career. In fact, prior to this stretch he had gone two games without a touchdown only once.

2016 record: 3-1

Week 4 ranking: No. 16

-4: The Texans are 3-1, but do they feel like a team with a winning record thus far? They are one of two teams with a winning record and a negative point differential of minus-4 this season.

2016 record: 3-1

Week 4 ranking: No. 10

18: Can the Ravens avoid playing such close games? Since the start of the 2015 season, Baltimore has played 18 games decided by eight or fewer points, including all four games this season. The Ravens have come out on the winning end three of four times, but it's a slippery slope.

2016 record: 1-3

Week 4 ranking: No. 8

831: Cam Newton is going through concussion protocol this week after he continued to take big hits. In his career, he has been sacked, hit while throwing or hit while rushing 831 times, which is 298 more than the next closest quarterback.

2016 record: 3-1

Week 4 ranking: No. 24

6-2: There are five quarterbacks who have posted a 6-2 record since Week 14 of last season: Ben Roethlisberger, Russell Wilson, Alex Smith, Kirk Cousins and ... Case Keenum. He might not be doing a lot, but he's doing enough.

2016 record: 1-3

Week 4 ranking: No. 5

5: Committing five turnovers in a game once is bad enough, but doing it in back-to-back weeks? You'd have to go back to 1992, when they were called the Phoenix Cardinals, to find the last instance of back-to-back five-turnover games for the franchise.

2016 record: 2-2

Week 4 ranking: No. 12

70.9: With Jamaal Charles back in the mix and a mobile quarterback to utilize, the Chiefs are a team that's built to run. But Andy Reid has had QB Alex Smith drop back to pass 70.9 percent of the time this season, tied with the Jaguars for highest in the NFL.

2016 record: 2-2

Week 4 ranking: No. 20

80 percent: Jordan Reed has been quiet this season, but when he gets involved -- like he did in Week 4 -- good things happen. Washington is 10-0 under QB Kirk Cousins when he completes at least 80 percent of his passes to Reed in a game (2-8 in all other games the two have played).

2016 record: 2-2

Week 4 ranking: No. 22

1: After falling to 0-2 to start the season, the Bills made a shake-up and we questioned it. Since then, the Bills have beaten the Cardinals, who entered their game No. 1 in NFL Football Power Index, and the Patriots, who entered their game No. 1 in NFL FPI.

2016 record: 1-3

Week 4 ranking: No. 19

10: The "Fitz-magic" is waning in New York as Ryan Fitzpatrick has been intercepted 10 times this season, including nine in the past two games. Vikings QB Daunte Culpepper in 2005 (10) was the last quarterback with as many picks through four games.

2016 record: 1-3

Week 4 ranking: No. 21

-32: The Chargers have led in the fourth quarter in each of their three losses this season. San Diego has outscored opponents by 51 in the first three quarters this season (second best) but has a league-worst minus-32 point differential in the fourth.

2016 record: 1-3

Week 4 ranking: No. 29

8,532: It's about an 8,532-mile round trip from Jacksonville to London, but maybe the Jags should consider doing it more? The Jaguars are 2-0 in London the past two seasons, 3-6 in Jacksonville and 1-8 in road games.

2016 record: 1-3

Week 4 ranking: No. 27

28.5: The Saints have scored 30 points in three games this season and have lost two of them. Only three teams have a higher scoring average than the Saints (28.5), yet New Orleans is 1-3 overall. The Saints badly need a defense.

2016 record: 1-3

Week 4 ranking: No. 17

7: Dating back to last season, the Lions' past five losses have all been by a touchdown or less. Through four games this season, the Lions have been outscored by seven points total but still sit 1-3.

2016 record: 1-3

Week 4 ranking: No. 23

15: No player has been sacked more than Andrew Luck this season. The Colts QB had never taken more than 10 sacks through the first four games of the season prior to 2016. How does he have 15 now and how has his protection only gotten worse in his career?

2016 record: 1-3

Week 4 ranking: No. 26

32.9: Marcus Mariota was selected second overall in the 2015 draft and while the team he plays for doesn't help, it might be time to start questioning his play. Mariota has a 32.9 Total QBR this season, second worst in the NFL.

2016 record: 1-3

Week 4 ranking: No. 31

15.5: The Bears won their first game in Week 4, but if they want more wins they'll likely need a stronger defense. The Bears are averaging 15.5 points per game this season, tied for worst in the NFL with the Titans.

2016 record: 1-3

Week 4 ranking: No. 28

8: Jameis Winston's eight interceptions are tied for second most in team history through four games, but the strange thing is that he has thrown all eight when not pressured. When he is pressured, he has five touchdowns to no picks. That's ... not typical.

2016 record: 1-3

Week 4 ranking: No. 25

24:58: The Dolphins are off to a 1-3 start and have averaged just under 25 minutes of possession time this season (worst in the NFL) despite playing an overtime game! A league-worst third-down conversion rate doesn't help matters.

2016 record: 1-3

Week 4 ranking: No. 30

29: Blaine Gabbert has some speed, but is it the best idea to have him run so much? His 29 rushes this season are tied for most in the NFL with Cam Newton, but Gabbert is averaging only 3.5 yards per rush.

2016 record: 0-4

Week 4 ranking: No. 32

0: The winless Browns have to play host to the Patriots in Week 5 for Tom Brady's return. Stranger things have happened, but the Browns are very likely to remain the only winless team through Week 5.
