The problem of shot selection in basketball
Brian Skinner

TL;DR
This paper develops a theoretical model for shot selection in basketball, determining when players should shoot based on shot quality and remaining opportunities, and compares predictions to NBA data.
Contribution
It introduces a model linking shot quality thresholds to remaining shot opportunities and turnover rates, providing insights into optimal shot timing in basketball.
Findings
Optimal shot quality threshold increases with fewer remaining opportunities.
NBA players tend to shoot too late, undervaluing turnover risks.
Model predictions align with observed NBA shooting behaviors.
Abstract
In basketball, every time the offense produces a shot opportunity the player with the ball must decide whether the shot is worth taking. In this paper, I explore the question of when a team should shoot and when they should pass up the shot by considering a simple theoretical model of the shot selection process, in which the quality of shot opportunities generated by the offense is assumed to fall randomly within a uniform distribution. I derive an answer to the question "how likely must the shot be to go in before the player should take it?", and show that this "lower cutoff" for shot quality depends crucially on the number of shot opportunities remaining (say, before the shot clock expires), with larger demanding that only higher-quality shots should be taken. The function is also derived in the presence of a finite turnover rate and used to predict the shooting…
