Hello. For those new to this blog here are the basics. I will keep updating this post in the future as I deem appropriate.

The Basics
All articles use Wins Produced and WP48 [Wins Produced per 48 minutes] to evaluate player’s performance.* This measure uses three key components to evaluate a player:
- The player’s per minute box score statistics
- The player’s team’s per minute box score statistics
- The average performance at the player’s position (PG, SG, SF, PF or C)
A full explanation can be found here. To give a general scale, an average player has a WP48 score of 0.100. The very best players in the league usually have a WP48 over 0.300. To put this in perspective; an average player who plays a full season at 40 minutes a game would generate around 6.83 wins for their team. In contrast, a player posting a 0.300 WP48 would generate about 20.5 wins at 40 minutes a game over an 82 game season.
I typically consider 400 minutes in a season a significant sample
I consider:
- a <.000 WP48 player a waste of a roster spot
- a .050 WP48 player a bench player
- a .100 WP48 player a starter
- a .200 WP48 player a star
- a .300 WP48 player a superstar
I may also talk about the half-baked notion and Wins over replacement Player (WORP).
The Stats
Stats used
- All basic NBA stats, including play time and salary are from Basketball-Reference
- The Player Efficiency Rating (PER) metric is the work of John Hollinger. The exact numbers are taken from Basketball-Reference. (***Warning***: Read this before attempting use
- The Win Shares (WS and WS48) metric is based on the work of Dean Oliver and Bill James. It is implemented by the fine folks at Basketball-Reference.
- The Wins Produced (WP and WP48) metric is the work of Berri and Schmidt. I use the Automated Wins Produced site (thanks Andres!!!) which is powered by data from Basketball-Reference and Yahoo Sports.
The Rules
- As long as you’re polite and don’t swear (excesively :-)). I will let you comment.
- I will make snarky and innapropiate comments. If you laugh great. If not, deal with it.
- Keep in mind that I will be wrong many many times in this space. I will also be right (hopefully at a higher frequency).

Arturo,
I am a student writing a paper analyzing NBA free agent movement and hoped you could give me some ideas as to how to find the data I need. I can’t find an email address for you, but please email me at the address I used to post. Thanks.
