This site is about risk management and the large element of chance in the NBA - concepts that are often overlooked by NBA executives, analysts and fans.
In short, this site tries to evaluate how NBA rosters can be built and managed more successfully. Usually, the two most important factors for a team's long-term success are luck and drafting well - in that order.
I recommend you read this to get an idea of the main points this site is trying to bring out. Once you read these core concepts, everything else I say should make more sense. Enjoy.
