The Panthers gain 94 fewer adjusted yards per game relative to an average offense against an average defense.What about defensive rankings?1) Calculate each team's offensive ANY/A for each game. Compare each team's ANY/A to the league average -- as of now, 5.88 -- and give each team a grade for each going. If a team had 28 pass attempts and 2 sacks, and averaged 6.88 ANY/A for the game, they'd have 30 pass plays and averaged 1 more ANY/A than average. That's a grade of 30. If a team has 46 pass plays, 4 sacks, and a 3.88 ANY/A average, that's a grade of -100. Calculate an offensive grade for each team in each of the 176 games each season.
2) Give each defense the opposite score of the offense. If an offense scores +50, the defense scores -50. By grading each offense and each defense in each game, that gives us 704 game-scores for the season. All game scores, of course, sum to zero.
3) Then, we can use the Simple Rating System to adjust each game score for strength of schedule. So passing offenses are adjusted based on the strength of the defenses they faced, which are adjusted based on the strengths of the offenses they faced, which are adjusted based on the strengths of the defenses they faced, and so on. After several hundred iterations, the ratings converge, and we receive true ratings for each teams.
Those ratings are presented below, in terms of adjusted net yards each offense produces above average per game:
