The New England Patriots and New Orleans Saints both lost this week, but that wasn’t enough to knock either from the top two spots of this week’s power rankings.

Why the lack of turnover at the top despite each team failing to secure a victory in Week 14? Unlike other power rankings, these take into account a team’s actual record, what its record should be based on points scored and allowed — also known as its Pythagorean win percentage — and how much better or worse its opponents are in relation to a .500 team. A good team playing against good opponents will be near the top, while one that struggles 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 Philadelphia Eagles are the third-most efficient team after adjusting for strength of schedule, per Football Outsiders, but will have to lean on backup quarterback Nick Foles after Carson Wentz suffered a torn anterior cruciate ligament against the Los Angeles Rams on Sunday. Those are big shoes to fill — Wentz was the second-most valuable quarterback in 2017 per ESPN’s total Quarterback Rating (74.5 QBR).

The last time Dallas Cowboys center Travis Frederick was responsible for giving up a sack by the game charters at Pro Football Focus was in 2014 during Week 9 against the Arizona Cardinals. He, along with the second-best run-blocking unit in the NFL this season per Pro Football Focus, has helped keep the Cowboys’ playoff hopes alive.

The Buffalo Bills are 7-6, yet after you adjust their margin of victory for strength of schedule they are 4.6 points per game worse than an average team. That’s bad enough to place them ninth in the AFC this season and rank as the 15th worst adjusted point differential in franchise history.

New England Patriots (-3) at Pittsburgh Steelers
Winner: Pittsburgh Steelers, 54 percent
Pick: Pittsburgh Steelers +2

The Patriots score a league-leading 2.6 points per drive while the Steelers allow just 1.6 (seventh best this season). Something’s got to give, with the winner gaining the upper hand on the No. 1 seed in the AFC.

Green Bay Packers at Carolina Panthers (-3)
Winner: Carolina Panthers, 62 percent
Pick: Carolina Panthers -3

The Packers get their star quarterback, Aaron Rodgers, back under center but might find it difficult dealing with the league’s top pass-rushing unit per Football Outsiders. According to their adjusted sack rate, which gives sacks (plus intentional grounding penalties) per pass attempt adjusted for down, distance, and opponent, no team has been better at getting to the passer than the Panthers this season (9.5 percent).

Los Angeles Rams at Seattle Seahawks (-2)
Winner: Los Angeles Rams, 55 percent
Pick: Los Angeles Rams +2

The Rams defense will have its hands full with Seahawks quarterback Russell Wilson. The 29-year-old has accounted for 32 of the team’s 33 touchdowns this season, three of those coming as a result of his ability to run with the football.

Los Angeles should be up to the task — according to Football Outsiders, its defense ranks fourth overall in 2017 and boasts the league’s No. 3 pass defense.
