Now through Week 6 of the 2019 NFL season, we at PFF have updated our power rankings using PFFELO. The top-10 has shifted significantly after the top-two spots, including two new teams moving their way in..
Like any ELO system, it adjusts the ranking of a team after each game based on what happened in the game and the perceived strengths of the team and its opponent prior to the game. As opposed to most other ELO systems, PFF ELO doesn’t use the final score to update the rankings. Instead, we compute what the final score should have been based on the player grades.
