Katherine Comer, W’26
Former Editor-in-Chief

Dear Readers,

I’m excited to share with you the Fall 2025 edition of the Wharton Sports Analytics Journal, including our new AI special feature. This semester, we are featuring innovative research in sports underrepresented in the literature such as badminton, junior tennis, and even speed cubing, along with works covering impactful sport business topics. 

We are also excited to highlight the increasing applications of AI in sports research. As Editor-in-Chief, I’m pleased that the journal is continuing to have a strong presence in sports analytics research for young researchers around the world and encouraging creative uses of AI in a variety of research applications. We are continually committed to being a platform where students can showcase research and foster knowledge among others in the sports analytics community.

As always, I’d like to invite any high school, undergraduate, or graduate student doing research in sports analytics to submit their work to the journal. We would love to consider your submission for our upcoming editions.

We hope this edition helps you gain a new perspective on the depth of questions that can be asked about sports and the breadth of new technologies and methods that can help find answers. As always, please let us know your thoughts and feedback as we strive to bring you the best of sports analytics.

Sincerely,

Katherine Comer, W’26

Using Markov Chains and Statistical Analysis to Model Intentional Fouling Situations in NCAA Division 1 Men’s Basketball

Intentionally fouling a team during their offensive possession is a strategy that basketball teams have employed for many years. Though popularized in the National Basketball Association (NBA), the technique has also made its way into Collegiate Basketball in recent years. The purpose of intentionally fouling is often to slow down opponent scoring and expose poor ...Read More

Re-evaluating the Qualifying/Finish Relationship in Formula One: A Replication and Correction of Prior Findings

Prior academic research in Formula One, most notably M¨uhlbauer (2010), concluded that starting grid positions were the strongest determinants of race outcomes while only examining the top eight finishers (fewer than 40%) of the competitors over a shortened sample of 4 seasons (2006–2009). This truncated sample approach limited the generalizability of its findings and likely ...Read More

PRSS: A New Metric to Quantify Pocket Collapses in the National Football League

In the NFL, “quarterback pressure” refers to defensive actions that disrupt a passer’s timing, decisions, and positioning. Numerous quantitative measures have been proposed, with mixed effectiveness. We introduce the Pocket Reduction Speed Score (PRSS), a geometric, tracking-based metric that quantifies how quickly the quarterback’s pocket shrinks. We apply the metric to player-tracking data from the ...Read More

AI Special Feature: AI-Assisted Substitution Decisions: A Fuzzy Logic Approach to Real-Time Game Management

With millions on the line every match, top soccer clubs still make critical substitution decisions based largely on intuition. This paper introduces an AI-powered Decision Support System (DSS) that brings data-driven rigor to one of the game’s most crucial tactical moments. Using fuzzy logic to model expert coaching knowledge, our system provides real-time substitution priorities ...Read More

Forecasting NFL Wide Receiver Touchdowns with a Temporal Linear Regression Model

Forecasting touchdowns for NFL wide receivers is a challenging but valuable problem in football analytics and player evaluation. Touchdowns are notoriously volatile, influenced by red zone usage, quarterback play, and situational variance, making year-to-year outcomes difficult to predict. This study develops a temporal linear regression model to project wide receiver touchdown totals using a feature-rich ...Read More

Quantifying the Drivers of Serve Effectiveness in Men’s Tennis

Tennis is one of the few sports in which the server initiates every point, making the serve the only stroke entirely under a player’s control. A powerful, well-placed serve can create immediate advantages, but identifying which characteristics most effectively translate serves into winning points remains unclear. Read More

Using Injury-Risk Forecasting to Quantify Financial Impact in the NBA

Injuries in the NBA have become consequential not only for team success but for the financial costs those teams suffer. This study develops a machine learning framework that predicts next-game injury risk using publicly available box-score data, player attributes, and injury history, then translates these probabilities into expected financial costs. Combining five datasets from 2010-2022, ...Read More

Modeling Realistic Placement Probabilities in Speedcubing Using Kernel Density Estimation (KDE)

This paper offers a simulation-based framework for predicting placements in official World Cube Association (WCA) competitions. Currently, the WCA uses psych-sheet rankings, which only present a competitor’s best average of five (Ao5) and singular solve. Our goal is to create a simulation framework that uses recent performance to estimate realistic placement probabilities. We construct kernel ...Read More

A Comparative Analysis of Rating Systems in the US Junior Tennis Development Pathway

The United States Tennis Association (USTA) has historically used point-per-round rankings to determine competitive tournament entry and seeding, but this system often rewards participation over quality of play and can be distorted by random draw effects. Alternative systems such as Universal Tennis Rating (UTR) and World Tennis Number (WTN) use algorithmic predictive modeling based on ...Read More
