Usage and True Shooting Tracker

I made a web app that allows you to see how the players on each team rate according to usage and true shooting. You can quickly get a sense for how players compare to one another and can sort by team or position.  The points are also sized and colored according to a player’s offensive rating, so you can see how much better (or worse) the team’s offense has been while they are on the court. The app will be updated as the season progresses so you can always see current stats.

As a bit of explanation, usage percentage is a measure of the percentage of possessions that a player “uses up” when they are on the floor. True shooting percentage is a measure of how efficient a player is shooting the ball.  It takes into account free throw shooting and the fact that 3’s are worth more than 2’s. High usage, high true shooting players are obviously really valuable.

Threes and Layups Season Simulator

By clicking on “Try it out here!” at the top of this post, you will be directed to what I am calling the Threes and Layups Season Simulator.  As a bit of background, Dean Oliver coined the term “Four Factors” in his revolutionary book Basketball on Paper. The four factors are, shooting, turnovers, rebounding, and free throws and these factors can completely describe a game of basketball. My Threes and Layups Season Simulator allows you to not only see how any team is currently doing on the year in terms of the four factors, but also tells you  what would happen to their efficiency (as measured by net rating) and their expected wins if you adjusted a part of their statistical profile!

Three Point % Predictions (Nov 27)

Have you ever wondered how seriously we should take hot or cold early season three point shooting? How many attempts would it take for a player to convince us that they have reached a new level in their outside shooting?

I was wondering the same thing, so I built a simple model using the 2016-17 season three point data. If you want to read a little more about the model, go here.

Below are the current three point percentage projections for all players with at least 20 attempts, as well as how the projection has changed from the beginning of the season.
