Draft Express released an article this week that elevated draft models based on algorithms to a higher status than they had previously enjoyed among many scouting communities. The article gave insight into the machinations of 5 different models, then looked at them in aggregate, by seeing how these models graded players on average.
These predictive models take a players numbers from whichever league they are currently ply their trade in, and attempt to translate them to the NBA based on how previous numbers have or have not translated. The accuracy of any single model is certainly up for debate, but ignoring their conclusions seems like folly in the modern era of NBA analysis.
