Despite popular perceptions and complaints about competitive balance in other professional sports, the National Football League (NFL) has become the most predictable league in America, according to recent analysis. Over the past 13 seasons, a significantly higher percentage of NFL regular season results have accurately predicted which teams would reach the Super Bowl compared to Major League Baseball (MLB) regular season performance predicting World Series participants.
Between the 2013 season and the present, just seven out of 32 NFL franchises have won the Super Bowl. Furthermore, only 11 organizations have reached the championship game. A concentrated group of teams, including the New England Patriots and Kansas City Chiefs, have dominated Super Bowl appearances, making up a substantial portion of the participants over the last decade and a half. This means only 22% of NFL teams have won the Super Bowl, and 34% have reached it in this period.
In contrast, MLB has demonstrated greater variability. Since 2013, nine different MLB organizations have won the World Series, representing 30% of the league. Additionally, 17 MLB teams, or 57%, have reached the World Series in the same timeframe. This data suggests that MLB, often criticized for its own competitive balance issues, has been less predictable than the NFL.
Regular Season Performance Predicts NFL Success More Strongly
The NFL's predictability is further underscored by the strong correlation between regular season performance and Super Bowl appearances. The best teams in baseball typically win around 60-61% of their games. In the NFL, top teams routinely exceed 80% winning percentages, with recent seasons seeing the best records at 14-3 (.824 winning percentage).
Since 2013, the average Super Bowl participant ranked second in the NFL's regular season winning percentage, with the median rank being first. This indicates that more than half of Super Bowl participants had the best regular season record in the league, and 58% of teams that reached the Super Bowl had the league's top record. In total, 23 out of 26 Super Bowl participants had a top-five record in the regular season, with 20 being in the top three.
This contrasts sharply with MLB, where the average World Series participant ranked 4.5 in regular season winning percentage, with a median rank of four. Only 26% of MLB teams reaching the World Series had the best regular season record. Moreover, several MLB teams that finished with lower regular season rankings, even outside the top ten, have reached the World Series. For instance, the 2023 Arizona Diamondbacks, who had the 13th best winning percentage, reached the World Series after sweeping the Dodgers in the National League Division Series. The 2021 Atlanta Braves, with the 12th best winning percentage, won the championship after defeating the Dodgers.
Factors Contributing to NFL Predictability
The analysis suggests that the NFL's structure, combined with factors like the schedule, the popular Red Zone channel, scoring trends, and the rise of fantasy football and sports gambling, contributes to its perceived predictability. While the NFL has structural benefits that create excitement, such as a concentrated schedule and high-scoring games, these elements may inadvertently mask a more predictable outcome for those who follow the league closely.
The perception that any team can win in a given season is challenged by historical data, which shows a heavy reliance on a few dominant teams and quarterbacks. Quarterbacks like Patrick Mahomes and Tom Brady have been involved in a significant portion of Super Bowl appearances over the last 13 seasons. The focus on point spreads in NFL betting also allows for engagement even when outcomes are more certain, further complicating the perception of predictability versus reality.
