PT-PM numbers for 2015-2016

I am belatedly getting around to releasing the final Player Tracking Plus Minus (PT-PM) numbers for 2015-2016. PT-PM is my version of a statistical plus minus model, that I have developed over the last few years.

I wanted to have a place to reference the numbers for future posts and put them out there for anyone interested. First a quick visualization, that pits the Defensive PT-PM against the Offensive PT-PM, with the color representing the overall score and the size of each player's marker determined by the number of minutes he played over the season. The visualization is filitered for players with at least 300 minutes. Plus I think it looks kinda cool.

 

Finally, here's the table with the O and D PT-PM numbers as well as the total score adjusted for playing time (lower minutes players are regressed more). Table can be filtered by team or minutes played.

 

 

Visualized Coaching

'Cause nothin' beats a scatterplot, or six.

(Update): After playing around with it a little there are some interesting differences by team.  I am glad I kept that filter, the metrics all love how the Spurs and Hawks assigned time.  Philly had the only negative slope I could find with Win Shares, meaning Win Shares thought Doug Collins was slightly more likely to play bad players than good.

Location Visualization

Below is the latest and greatest visualization for shot location, percentages based on percent of all shots taken at the rim or from three.. It defaults to show Wings, but you can change the filter for the Guards types and by year.  One can also see the Bigs, if you include everyone, but (spoiler alert!) they don't shoot many threes so there's less to see.

Guard Location Viz

Below the break is a visualization of Guards' shot location broken out by my cluster analysis groups, Slashing Guards and Stretch Guards based on their percent of attempts at the rim versus from three...
