The science behind Value Add Basketball is laid out in Cracked Sidewalks pieces between May 2011 and now. A massive effort to upgrade the system and pinpoint the impact each player had on his team's Offensive and Defensive Efficiency Ratings culminated at the end of 2015 with Value Add Version 3.0, 1000 lines of code, a series of improvements detailed here, and a simple explanation with illustrative tables to make the impact of each player easy to understand.
Others such as the Basketball Prospectus took the formula and suggested additional calculations based of the system, and Version 4.0 was introduced at the outset of the 2016-17 season to measure the potential value of players based on how valuable they could be if they played 67% of the minutes and had 24% of the possessions during that time on the court.
Articles on the Value Add Basketball system appear in places such as the University of Arizona basketball site, Big Apple Buckets, Bleacher Report, Breitbart (700+ articles), ESPN (another ESPN draft guide), ESPN the Magazine, Fox News, Fox Sports, Northwestern State University, the Times-Picayune, Sports Illustrated the Washington Post, blogs like Xavier Hoops Rumors and TV stations such as this one.
The system is similar to baseball WAR. However, while WAR measures one "replacement player" taking the place of a start player, in Value Add pin points the number of POINTS each college player is worth due to the "domino effect" of the impact on the entire game rotation when the player is lost.
