Aikman Efficiency Ratings: Week 5
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.)
(Oct. 11, 2006) --
The Colts, Eagles and Chargers remain one-two-three in the Offensive Aikman Efficiency Ratings -- but the Bears' rise to fourth in the NFL's yardage ranking is matched in the Aikman.
"Aikman" offenses that are outperforming their yardage totals continue to include the Bengals, Texans and Seahawks (naturally, since they were all on bye last week). A newcomer to the ranks -- the Jaguars.
Jacksonville rose from 18th to 15th after gaining "only" 312 yards in their 41-0 win over the Jets. But they advanced from an Aikman Offensive rating of 71.8 to 80.5 and from 20th to eighth in the rankings. Playing turnover-free football and scoring 35 of 35 possible points in the red zone will do that.
The Ravens remain ahead through Week 5 in the Aikman Defensive Ratings, but the Bears have closed the gap to just 2.6 points.
The Bears are the new leaders, ahead of San Diego, in the Aikman Combined. Five of the top six teams at the moment, all but Chicago, did not make the playoffs last year.
The defensive trend reflected elsewhere in the NFL in 2006 also shows in the Aikman Efficiency Ratings.
Last year, six offenses and two defenses finished above 85.0 with the league offensive average checking in at 75.6 -- slightly better than the norm of 75.0.
So far in 2006, only one offense and five defenses are above 90.0 with the league offensive average down to 74.5.

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).
