Stephen Curry’s record-setting month for shooting threes

Steph Curry has been on a tear as of late. In April he made more threes than any NBA player ever has in a month. Ben Golliver and Artur Galocha for The Washington Post provide perspective on just how record-setting Curry’s current play is. I’d be lying if I said it wasn’t satisfying to see half of the comparisons show how Curry has played better than James Harden. Tags: basketball,...

Basketball court designed as a national park map

Kirk Goldsberry, whose basketball charts you might recognize, made the Naismith International Park Map: This map blends two of my passions: cartography and hoops. The elevation surface on the map is derived from the most common scoring areas in the NBA during the 2019-20 season. Higher places indicate the areas where NBA scorers scored the most from. Naturally this includes the areas near the rim and the areas just outside...

Data for all of the referee calls in NBA games

Owen Phillips compiled per game and cumulative foul calls for all NBA referees between the 2016-17 and 2019-20 seasons. On its own, I’m not sure it’s that exciting, but if you’re into basketball analytics, it might be fun to tie in with other data. Tags: basketball, Owen Phillips, referee

NBA playoff win probabilities, animated over time

FiveThirtyEight publishes win probabilities for NBA games throughout the season. During the playoffs, they show chances of winning each round, and with each game, the probabilities shift. Adam Pearce animated these shifts, from the start of the playoffs up to now. Nice. The visualization. Not so much the Lakers. Tags: Adam Pearce, basketball, FiveThirtyEight

Looking for similar NBA games, based on win probability time series

Inpredictable, a sports analytics site by Michael Beuoy, tracks win probabilities of NBA games going back to the 1996-97 season. When a team is up by a lot, their probability of winning is high, and then flip that for the losing team. So for each game, you have a minute-by-minute time series of win probability. Beuoy added a new feature that looks for games with similar patterns a.k.a. “Dopplegamers”. Tags:...

FiveThirtyEight launches new NBA metric for predications

FiveThirtyEight has been predicting NBA games for a few years now, based on a variant of Elo ratings, which in turn have roots in ranking chess players. But for this season, they have a new metric to predict with called RAPTOR, or Robust Algorithm (using) Player Tracking (and) On/Off Ratings: NBA teams highly value floor spacing, defense and shot creation, and they place relatively little value on traditional big-man skills....

Exploration of players’ shot improvement in the NBA

Wondering whether if a player’s shot improves over the course of his career, Peter Beshai shows shot performance for all players from the 2018-19 season: To understand whether or not a player actually gets better over time, we need some kind of baseline to compare their current performance against. On Shotline, the baseline is set after a player completes their first season in the NBA and has shot at least...

Simulation of fan emotions during a basketball game

During a game, the range of emotions can vary widely across a crowd. Will Hipson, making use of some emotion dynamics, simulated how that range can change through a game: What I’m striving to simulate are the laws of emotion dynamics (Kuppens & Verduyn, 2017). Emotions change from moment to moment, but there’s also some stability from one moment to the next. Apart from when a basket is scored, most...
