The rankings incorporate offensive, defensive and special-teams metrics, with a focus on yardage per play, adjusted per-possession efficiency (including points per possession) and the rate at which teams gain and prevent first downs. Strength of schedule and error rates (penalties and giveaways) are also factored into the calculation.
Possession data is adjusted to eliminate kneeldowns or other obvious scenarios where the offense is not attempting to advance the football.
1. New England Patriots (10-1)
Last week: 1
One loss wasn't going to knock them off the top spot; they are first in offensive per-series efficiency, first in special-teams efficiency and 10th in defensive per-series efficiency.
