In preparing the numbers for this piece, I ranked every category for every season for every player in my database, going back to 1979-80. There were 15,035 player-seasons in the data. In that step of the analysis I included scores for turnovers, so there were nine categories per player. So that means there were 135,315 category scores in the rankings.
My thought before the exercise was that even though 3-point shooting is so much more prevalent in today's NBA, Curry's dominance in that one category would be so overwhelming that he might well have the highest marginal value in that one fantasy category than any other player has had in any other category in any other season. He did not. Curry's 3-point score ranks 18th among all categories, as his off-the-charts 3-point shooting this season simply can't overcome the marginal value gained by outliers in years past who had high 3-point totals in league environments where those shots were still rare.
However, I found a surprise at the bottom of the rankings, where a score from this season stood out as the absolute worst of the worst, ranking No. 135,315. That score belongs to Detroit's Andre Drummond for his free throw shooting. The bottom of the board is populated entirely by terrible free throw shooters like Drummond, DeAndre Jordan and Shaquille O'Neal. But once you account for league factors, Drummond's percentage and the volume of his free throw attempts so far in 2015-16, no one's ever done it worse.
