I was going to start a series updating the ability of the different NBA productivity metrics to predict future outcomes today, but then I remembered that if certain bills were passed by Congress, I could very easily have my website shut down in the future if I said anything even interpreted as negative about one of them. Did I say something mean about APM again? Maybe basketballvalue wants to exercise a copyright. Is PER kind of useless? Maybe ESPN has had enough. Am I completely ignoring NBA Efficiency but I have it in my publicly-available database? The NBA may decide that I don’t have written consent. I think many of us take the internet and its resources for granted, but it doesn’t have to be that way.
On a more positive note, enjoy these graphs about correlation and causation.
