I think this would work well if the recruiting rankings weren't also focused on NBA potential or if players were evenly dispersed across teams of equal abilities. I'm sure if Alan Griffin's bro played for Kent State, he could have put up even more ridiculous numbers than playing for Duke. And now he's a one and done after not playing a full season. His WAR probably would show he was a bust but he'll be a lottery pick. You'd somehow have to factor in the post college life of a player potentially. And the draft slot may not be good evaluation tool either. You have guys like Skal Labissière getting drafted on potential they never quite reach (sigh for another blown Kings pick). So, I think it would be very hard to do just on numbers alone. You'd probably need a qualitative element.
