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!
