Can We 'Solve' Sports?

Is it possible to make a sport too good? Professor Hannah Fry and Michael Stevens explore how science, data, and optimisation are transforming modern sports improving athletes and teams, while quietly changing how games are played, watched, and understood. From the Tush Push in the NFL and defensive

Episode Summary

Executive Summary: The episode argues that sports science and data optimization improve performance but can also make games less entertaining by eliminating uncertainty, athletic flair, and “unnecessary obstacles.” Using baseball, Formula One, football, cricket, basketball, and Olympic running, the hosts explore how rules constantly evolve to preserve competition, spectacle, and the human drama that makes sport feel like sport.

Main Topics: The optimization paradox in sport (Priority: 5/5): The hosts frame a central tension: analytics and engineering help teams win, but over-optimization can reduce unpredictability, beauty, and spectator enjoyment. Baseball and the launch-angle/defensive-shift revolution (Priority: 5/5): Statistical thinking pushed baseball toward home runs, walks, and strikeouts, leading teams to adopt defensive shifts that were effective but often made play less dynamic and exciting. Limits of human performance and Olympic records (Priority: 4/5): They discuss how elite human performance is approaching physiological ceilings, so future improvements are increasingly marginal and dependent on rules, equipment, and conditions. Formula One and dirty air (Priority: 5/5): Aerodynamic optimization created turbulence for cars behind the leader, making overtaking harder and prompting rule changes such as redesigned cars, DRS, and future boost-style systems. Data analysis in football and the NFL (Priority: 4/5): The conversation contrasts the complexity of American football with soccer’s data revolution, highlighting player-tracking models, expected goals, and AI simulations that reshape tactics and recruitment. Cricket, reverse swing, and the spirit of the game (Priority: 4/5): Reverse swing is presented as a physics-based innovation that pushed the game’s limits, but also raised questions about ball tampering and what counts as fair play. Enhanced sports and future rule changes (Priority: 4/5): They consider future leagues that openly allow performance enhancement or extreme biomechanical changes, arguing that sports will keep reinventing itself to preserve competition and spectacle.

Key Arguments: Data-driven optimization tends to improve winning probability for individual teams or athletes, but can flatten the uncertainty and expressive skill that make sports enjoyable to watch. Sports are defined less by fixed rules than by an ongoing need to preserve challenge; when tactics become too automatic, regulators add new obstacles or ban the strategy. Baseball’s defensive shifts show how statistical advantage can make the game less aesthetically appealing even when it is strategically correct. Formula One’s aerodynamic innovations created “dirty air,” reducing overtaking and forcing repeated regulatory resets to restore race drama. Elite athletic records are nearing physiological limits, so future gains are likely to be tiny and increasingly dependent on marginal equipment or environmental advantages. In football and the NFL, advanced tracking data and AI can evaluate players and simulate decisions, but the sport can avoid total predictability because the game is too complex and rules can be adjusted. Cricket’s reverse swing demonstrates that sports can develop ingenious, physics-based techniques that sit on the edge between genius and cheating. Even when an action is statistically suboptimal—like goalkeepers diving on penalties—humans often choose it because sports are also performances and stories, not just optimization problems.

Data Points: Baseball defensive shifts in 2010: 3,323 - Number of team shifts based on batter statistics in Major League Baseball during the 2010 season. Baseball defensive shifts in 2017: 33,218 - Number of shifts in MLB by 2017, showing an order-of-magnitude increase. Rob Deere three true outcomes rate: About 50% - He produced a strikeout, walk, or home run about half the time, compared with a league average of about 25%. League average three true outcomes rate: About 25% - Used as the baseline to show how unusual Rob Deere’s profile was. Formula One downforce loss in dirty air: 20% to 60% - Modern F1 cars can lose this much downforce when following another car, depending on track and corner. Estimated share of potential in world records: About 99% - A cited paper argues current world records are near humanity’s physiological frontier. Marathon world record in 1908: 2:55:18 - Starting point for the discussion of how marathon records have progressed over time. Marathon record improvement over next 50 years: 40 minutes faster - Shows early rapid gains in endurance performance. Marathon record improvement over following 50 years: 10 minutes faster - Shows slowing progress as the physiological limit is approached. Marathon record improvement since then: Less than 4 minutes - Illustrates how marginal modern gains have become. Target 100-meter dash limit: 9.44 seconds - A study’s estimate for the fastest possible human 100m time. Usain Bolt’s world record comparison: 0.14 seconds slower than estimated limit - Used to show how close elite sprinting is to the theoretical ceiling. Cheetah ground contact at top speed: 70% - Used to argue that more continuous ground contact can increase speed. Usain Bolt ground contact at record run: 43% - Contrasted with cheetah biomechanics to motivate four-legged running speculation. Penalty kick goalkeeper dive behavior: 94% dive rate - Goalkeepers still dive almost always despite evidence that standing still stops more shots. Penalty kick save rate when standing still: About one-third - Psychology study result cited as more effective than diving. Penalty kick save rate when diving: 13% - Used to demonstrate action bias and suboptimal human decision-making. Estimated chance of a 7-foot-plus American male age 20-40 being in the NBA: 17% - Statistic cited to illustrate height-based selection in basketball. Number of U.S. men over 7 feet tall age 20-40: About 70 - Used in the basketball optimization discussion. NBA players over 7 feet tall: 13 - Compared against the pool of eligible tall men to highlight scarcity and selection concentration.

Pivotal Quotes: "a game is a voluntary attempt to overcome unnecessary obstacles." — Bernard Suits (quoted by hosts): Used as the philosophical core of the episode to explain why over-optimization can make sport less fun. "We want to watch problems, not solutions." — Hannah Fry / Michael Stevens: Summarizes the argument that spectators prefer uncertainty, struggle, and improvisation over perfect efficiency. "If the Eagles were in a fourth and one situation, they weren't. They were going to be. To get a first down, and it was just like watching a big scrum of people slurp forward." — Hannah Fry: Describing the NFL tush push as an example of an overly effective but potentially boring strategy.

Implications: Sports will keep being reshaped by analytics, engineering, and biomechanics, but leagues must continually add or change rules to preserve uncertainty, fairness, and spectacle. The future may split into optimized, enhanced, and tradition-based versions of the same sport.

About The Rest is Science

Join mathematician Professor Hannah Fry and science creator Michael Stevens (Vsauce) as they dig into the weird scientific questions that often go unexplored. Welcome to The Rest Is Science, a show that sits in the fascinating space between what we think we know, and what we actually know. Why do we assume we understand things like time, randomness, or even gravity? Once you start questioning these familiar ideas, reality becomes astonishingly strange and completely fragile. Whether you're a lifelong science fan or just naturally curious, The Rest Is Science will change your perception of reality, and prove that the biggest questions are always the most fun.
