The Kansas City Chiefs remain undefeated and take over the top spot on this week’s power rankings, which take into account a team’s actual record, what their record should be based on points scored and allowed — also known as their Pythagorean win percentage — and how much better or worse their opponents are in relation to an 8-8 team. A good team playing against good opponents will be near the top while those who struggle against mediocre or poor teams will trend toward the bottom. A more detailed description of the method can be found in the Week 1 rankings.

The Chiefs looked like a Super Bowl contender before the regular season started and have done everything to prove the believers right. According to Football Outsiders’ Defense-adjusted Value Over Average, which measures a team’s efficiency by comparing success on every single play to a league average based on situation and opponent, Kansas City boasts the league’s No. 1 offense supported by the No. 11 defense, making it one of the most well-rounded teams in the league.

Two wins over the Carolina Panthers and Miami Dolphins help push the New Orleans Saints up the rankings, with the former looking better after the Panthers beat the New England Patriots on Sunday. Defense is still an issue for the Saints, but opponents are converting only 44 percent of their red-zone opportunities, which is a below-average rate (54 percent) in 2017.

The Ravens are in a free fall after back-to-back losses to the Jacksonville Jaguars and Pittsburgh Steelers. After adjusting their scoring margin for strength of opponent, Baltimore is being outscored by more than 11 points per game, the fifth-worst differential in the league this season.

Green Bay Packers at Dallas Cowboys (-2)
Winner: Green Bay Packers, 60 percent
Pick: Green Bay Packers +2

Dallas will have its hands full this week. The Packers are No. 1 in red-zone efficiency (11 touchdowns on 14 drives, 78.6 percent) and are only forced to go three-and-out less than a third of the time (29.5 percent). Defensively, meanwhile, Green Bay is one of only six teams that has held opponents to fewer than 300 yards a game (299.5).

New England Patriots (-5.5) at Tampa Bay Buccaneers
Winner: New England Patriots, 63 percent
Pick: New England Patriots -5.5

The Patriots’ struggles on defense are well-known by now: They allow the most net yards per pass attempt, the second most rushing yards per carry and the most points per drive this season. But one bright spot has been the play of defensive end Trey Flowers.

Flowers has been credited with 20 total sacks, hits and hurries by the game charters at Pro Football Focus, with almost an equal split coming from the right and left sides of the defensive line. He also has six stops against the run at or behind the line of scrimmage, including a forced fumble against the Panthers in Week 2.

That will be a problem for Buccaneers guards Kevin Pamphile, J.R. Sweezy and Evan Smith, who rank 49th, 35th and 29th, respectively, for their pass-blocking ability among 75 qualified guards, per Pro Football Focus.

Minnesota Vikings (-3) at Chicago Bears
Winner: Minnesota Vikings, 68 percent
Pick: Minnesota Vikings -3

The Bears will start rookie quarterback Mitch Trubisky, the No. 2 pick in April’s NFL draft. Since 1999, the earliest data available, there have been 48 quarterbacks 24 years old or younger that made their debut during the first half of the season. Just a third (16) of them had an outing that resulted in an above-average rate of adjusted yards per pass, which gives a bonus for touchdowns thrown and a penalty for interceptions.
