The Basics

I got tired of including this in each and every post. So, from now on, I'll pull an Arturo and this will be its own page that I will link to at the top of every post.

This article uses the Wins Produced metric to discuss the productivity of NBA players. This metric is based on box score statistics that are adjusted for other factors including pace, position and team. A general scale is given for this, and links to advanced explanations are listed at the bottom of the page.

Wins Produced per 48 Minutes (WP48) – The number of wins a player produces in 48 minutes of play. 0.100 is average and 0.250 is considered the “superstar threshold”. A player a WP48 of 0.000 produces no wins, and any player with a negative WP48 produces a negative number a wins (or, if you prefer, a positive number of losses)

For more information on the terms used in this post, please consult the Glossary of Terms.
