Rails app to populate a PostgreSQL database containing every shot attempted in the NBA since 1996.
Blog post with some analysis of the data: https://toddwschneider.com/posts/nba-vs-ncaa-basketball-shooting-performance/
Data comes from the NBA Stats API. As of March 2018, the database contains ~4.5 million shots from 2,000 players, and takes up 1.5 GB disk space.
NCAA data is available via Sportradar on Google BigQuery. The
mbb_pbp_sr table contains men's basketball shot chart data since 2013.
git clone [email protected]:toddwschneider/nba-shots-db.git cd nba-shots-db/ bundle exec rake db:setup
Import all available data (will take a few hours):
bundle exec rake import_all_shots bundle exec rake jobs:work
Alternatively, import data selectively by going into the Rails console and running, e.g.:
lebron = Player.find_by(display_name: "LeBron James") lebron.create_shots(season: "2017-18", season_type: "Regular Season") Delayed::Worker.new.work_off
COPYcommand instead of Rails's
COPYis ~10x faster
player#create_shotsdeletes and replaces data every time it is run.
The original version of this project had a table called
closest_defender_aggregates that included player/season aggregates segmented by shot distance and the distance of the closest defender at the time of the shot.
Unfortunately, as of December 2020 (and perhaps earlier), it seems like the NBA API no longer makes this data available. The
NbaStatsClient#shot_stats_by_closest_defender method currently only seems to work if the
shot_dist_range argument is empty. This means you can get a player's shooting performance segmented by closest defender distance, but you cannot further segment by shot distance.
The BallR shot chart app hits the NBA Stats API directly. In the future, it might make sense to expose an API interface from NBA Shots DB, then have BallR use that API instead of the NBA Stats API. In that world, BallR would be able to support more advanced options like career-long charts, team-level shot charts, etc.
BallR also has a college edition that uses the Sportradar data to make college basketball shot charts.
