We came up with a new metric based on opponents’ shooting data.
Unsurprisingly, the highest-rated defender over the past five seasons according to DRAYMOND is Draymond Green. Last season it was Derrick Favors.
Lowest-rated defender over the last five seasons according to DRAYMOND: Rajon Rondo. Lowest-rated last season: Collin Sexton (followed somewhat surprisingly by Trevor Ariza).
Haven't really had time to ponder their methodology — I'm generally somewhat skeptical of Nate Silver, and of defensive metrics that are based on things other than plus-minus over the largest possible samples (ideally regressed for quality of teammate but not for boxscore stats). But of course I love the name, and am always curious to hear what the MBPC crew think.
