* They do not take strength of schedule into consideration. Putting up great numbers against the Ivy League is a lot different from putting up great numbers against the Big Ten.
* They do not consider the college players who never make the pros. Since they include only players who eventually made the NBA, their analysis suffers from survivorship bias.
I hope to develop my own system that addresses these issues. Until then, I’m not convinced that these analysts are as clairvoyant as they claim.
edit: Hickory High does not claim to translate college performance into NBA performance. Instead, it uses similarity scores to compare draft prospects from different years.
