Aikman Efficiency Ratings: Week 2
By Troy Aikman
Special to NFL.com
NOTE: In 2004, Pro Football Hall of Famer Troy Aikman devised a formula for measuring the efficiency of NFL offensive and defensive units. While the league ranks these units based on total yards per game, Aikman wanted to create a more comprehensive ranking similar to the QB passer rating. Each week during the season, Aikman will post his updated ratings on NFL.com. (See below for an overview of the factors that contribute to the Aikman Efficiency Rating.)

Aikman Efficiency Ratings Formula
The Aikman Efficiency Ratings measure offensive and defensive performance using a combination of seven key statistics identified by Troy, and then measured against league norms (and extremes) established over the last 10 years. An offense or defense performing exactly at league norms in all categories will achieve a score of 75. The better the offense or defense, the higher the score on either scale.
It will take a truly exceptional unit to score more than 90 during an entire season on either the offensive or defensive scale. Higher scores are possible in individual games.
In 2005, AER scores ranged on offense from 92.6 (Seattle) to 60.9 (San Francisco) and on defense from 89.3 (Chicago) to 61.1 (Houston). The seven categories measured are:
Adjusted Points (20%) -- Total Points Scored or Allowed minus Points on Returns and Safeties
Turnovers (20%)
Red Zone Efficiency (20%) -- Measured by Percent of Possible Points (see below)
Yards Per Play -- divided into Yards Per Rush (10% of total) and Yards Per Pass Play (10% of total). Yards Per Pass Play includes yards on plays involving sacks.
First Down Achievement -- divided into Total First Downs (10% of total) and 3rd Down Conversion Percentage (10% of total)
Percentage of Possible Points in the Red Zone is figured by taking the number of Red Zone Chances times 7, then dividing it by the number of Points Actually Scored (defined as TDs times 7 plus FGs times 3).
