Week 4 of the NFL season is in the books, and with it, a fourth week of 2016 grades in the PFF database. With a quarter of the season now behind us, the Pro Football Focus analysis team is excited to release our NFL Power Rankings, listing all 32 NFL teams in order by overall grade to this point in the season.

You can check out the complete Power Rankings here.

Each team’s overall grade is a cumulative metric that takes into account the grade of every individual player on a team’s roster—which can be even further broken down to a snap-by-snap level.

We’ll be updating our Power Rankings each week through the remainder of the 2016 season.

Heading into Week 5, the Denver Broncos top the list, with their well-balanced defense doing most of the heavy lifting to this point. It’s certainly worth noting, however, that Gary Kubiak’s offense is a top-four graded unit this season, due largely to impressive receiving and run-blocking.

At No. 10 overall, the Dallas Cowboys have impressed thus far in 2016, trailing only the Philadelphia Eagles in the NFC East by half a game. Rookies Dak Prescott and Ezekiel Elliott, along with strong O-line play from Zack Martin and Travis Frederick, have the offense currently grading among the league’s five best units. On the defensive side of the ball, however, there’s certainly room for improvement, with Dallas earning the ninth-lowest defensive grade thus far, largely due to issues along the front-seven.
