Aikman Efficiency Ratings

10

AIKMAN RATINGS (Week 1 Commentary)

Although the Aikman Ratings were devised by Troy Aikman in 2006 (and have been administered in that period by Stats, LLC), this is in effect their 20th anniversary season, as the Aikman Ratings database goes back to 1995 when “Inside the 20” information became reliably available.
 
The ratings came about as Aikman noticed that the NFL’s “official” method of measuring offensive and defensive performance consisted exclusively of total yards gained.  While yards gained is an important, and sometimes critical, measure, other vital factors of offensive performance, such as actually scoring points and controlling the ball without turnovers so that the opponent doesn’t score are irrelevant as the NFL pronounces its top offenses and defenses.
 
Aikman believed this to be too simplistic a method towards determining whether an offense or defense achieves its true goal – contributing to winning.
 
The goal therefore was to create a system that measured factors related to winning without becoming subjective or too intricate.  And so in 1996, the Aikman Ratings came to be – a measurement of seven key, but easily obtained, statistical measurements (yards per rush, yards per pass play, turnovers per game, first downs per game, third-down percentage, points per game (unit on field) and points per red zone possession) combined and expressed in one simple number.  
 
At the time, that average number for an offense or defense was 75 on a scale that extends roughly to 100 or 50 in normal situations.  As a practical matter, the expansion of offense in the intervening nine years has produced an offensive average above 80 and a defensive norm below 70.
 
Here are our first ratings of the year, which as a practical matter only express a team’s performance in one game.  The Vikings dominated the Rams more thoroughly than any team this week, the Falcons offense dominated the Saints defense completely, and the Eagles defense had the best day relative to the Jacksonville offense.
 
As the weeks pass, we’ll learn more about the true nature of each team’s offensive and defensive units and we invite you to check us out here throughout the season.
