With our history-making season in the books, enjoy these final ratings for 2009.
RATINGS COMPUTATION (must-read for new readers):
At its heart, this is a VERY simple method of calculating ratings, using only two stats. The results aren't meant to be a perfect reflection of the real world; don't focus too narrowly on exactly where each team's totals are ranked. The two components (O and D ratings) are often more revealing than the totals, don't overlook those.
Here's how the ratings are calculated. The first step is to calculate two simple stats: Points For per Game, and Points Against per Game, for each team. These two leaguewide data sets for offense & defense both conform to a "Bell Curve", or Normal Distribution, that can be graphed. Depending on where each team lies on that graph, they have a value between 0 and 1. (This isn't something pulled from thin air. It's a very common, standardized statistical analysis technique. The purpose is to more accurately measure each team's position within the ‘population' of all league teams.) You now have every team rated from 0 to 1, on offense and on defense. Add those two numbers and you've got a total rating for each team. Last, multiply by 50 to convert the ratings onto a 0-to-100 scale, making them more readable and intuitive. There you go. Simple, right?

Several lopsided games made for lots of movement in the rankings. The 49ers moved up 4 spots, Packers and Vikings up 3. Colts and Bengals dropped 4 slots, Cardinals down 3.
It's been fun discussing all manner of numbers with youse guys this year. Cheers!
