Welcome to FSPI

FSPI stands for Final Score Power Index. Generically, it's any method for assigning a numerical power value to teams in a league, based on the final score(s) of the games each team has played. One example is the "Simple Ranking System", described in this blog post on pro-football-reference.com.

Once each team has a power index, teams can be sorted from most to least power to yield a power ranking. If the power index is predictive, it can also be used to predict winners of upcoming games.

This blog will use various power index algorithms (including some variant of SRS) to follow teams over the course of the NFL season. That means most of the traffic will be from August to February. But I didn't want to wait until August to figure out how to drive blogger, and this will give me an incentive to get my software ready to go.

So welcome, and thanks for reading.
