Welcome to BasketballValue.com
This site is intended to be a source of both advanced statistical analysis of the NBA and the data required to perform such analysis. Hopefully, you'll find this site of value whether you're looking for NBA statistics that aren't available in a box score or you're looking to perform your own analyses.

Currently, BasketballValue.com focuses on calculating the impact an NBA player has when he's on the court. Adjusted +/- overall ratings are presented for the 2007-2008 regular season, the 2008 playoffs (combining those results with the regular season), the 2008-2009 regular season, and the 2009 playoffs (again combining the results with the regular season). These calculations are in the spirit of the work of Dan Rosenbaum. They aim to assess all the contributions a player makes when factoring in the strength of his teammates and opponents. Additional information on how these adjusted +/- ratings are calculated has been published on 82games.com.

These numbers are updated constantly throughout the season. In addition to adjusted +/-, the site also contains net (on court - off court) ratings for overall team performance, offense, defense, and offensive and defensive rebounding. Data going back to the 2005-2006 is available for download by the basketball analytics community. The performance of individual players as well as 5-man units can be viewed on this site. Additional work on the value of holding an NBA draft pick has been published on 82games.com.

If you have any feedback, or download any data, please drop a line at webmaster@basketballvalue.com. You can also post your thoughts on the APBRmetrics forum basketballvalue.com thread.
