Stats 101 Part 4 (early access)
Added 2019-09-28 18:46:11 +0000 UTCHere's an early look at the fourth installment of the Stats 101 series on YouTube. Many of you have asked for a video on my playmaking metrics, and here it is. More details can still be found on backpicks under "metrics." Additional sources:

Box Creation updates that incorporate spacing for better historical accuracy: http://www.backpicks.com/2019/07/13/box-creation-update-improving-accuracy-across-eras-patreon-only/
A slightly different involvement rate that incorporates screening but counts all assists equally: https://fivetimesfive-blog.com/2017/05/22/new-statistics-involvement-rate/
An early-tracking involvement rate that uses FT assist data and foul drawing: https://fansided.com/2014/08/08/re-imagining-offense-multiple-credit-possessions-true-usage/
More on assist:turnovers:
Including all of these stats (box creation, passer rating and offensive load) to many models has improved performance, including my own version of BPM. I think (hope) in the near future that we'll be able to leverage more tracking data to have even better playmaking metrics, both as a one-number summary and as conditional metrics (eg transition passing performance given context X).
