I can publish a google doc at some point for people to take a look at. I'll also post lists sorted by PDIFF when I have the 2023 data set complete.
The inputs go beyond raw stats and do already include elements of athleticism and birth date. I'll summarize these at a high level:
Birth date - The database produces an average age. If a player is below that average age (more theoretical time for development), they get more credit for their production. If they are above that average age, they get less. This is meant to more marginally tip the scales between like prospects and also places a handicap on older players, that they need to play through. So it isn't that you shouldn't take older players......it is that you should only take older players, that generate truly unique production through an age handcuff.
RAS - it isn't exactly NFL RAS........but there is a single number input that is generated based on (ideally) testing from the combine. An average NBA athlete is a 7.5 on a 10 scale. So think, Luka Garza is like a 5 out of 10. Being a 5 out of 10 doesn't disqualify you, it just means that your production needs to hit a higher output threshold than someone who is a 10 out of 10.
In the end, these elements are a mixed average and are then used to either marginally increase or decrease their relative production vs. their peers. So in an ideal world, we want young, athletic guys who produce......but there's a short supply of those guys and if that is all we cared about......we'd be missing the Draymond Green's, Desmond Bane's, etc, etc of the world.
The model I have put together over the years is flexible.......it handcuffs players in specific ways, like described above and sees which players on various points of the age / athletic spectrum still produce at unique levels relative to their peers. So that teams have a better chance of evaluating who are the likely producers from a much larger bucket (any age, athletic, production profile).
Sorry if this was too in the weeds but that is what my model is attempting to do with draft prospects.
