Recent data on professional sports championships underscores a growing predictability in the National Football League (NFL) that eclipses concerns about competitive balance in Major League Baseball (MLB). While fans often lament the dominance of a few baseball clubs, the numbers tell a different story when the NFL is examined over the same period.
Super Bowl Concentration Since 2013
From the 2013 season through the 2025 season, just seven of the league’s 32 franchises have captured the Super Bowl. That translates to roughly 22% of teams winning the championship. Even fewer—only 11 teams—have earned a berth in the title game, representing 34% of the league.
Four franchises account for the majority of recent appearances: the New England Patriots, Kansas City Chiefs, Philadelphia Eagles and Seattle Seahawks. The Tampa Bay Buccaneers, led by Tom Brady, provide the only other recent champion.
Baseball’s Wider Field of Winners
In contrast, MLB’s World Series has been claimed by nine different clubs out of 30, a 30% championship share. Moreover, 17 teams—57% of the league—have reached the Fall Classic during the same span. The disparity suggests that baseball’s postseason remains more open to a variety of clubs.
Regular‑Season Success vs. Championship Odds
One key factor is the gap between regular‑season performance and postseason outcomes. In the NFL, the top teams routinely post winning percentages above 80%, with the best records in the last two seasons standing at 14‑3 (.824). By comparison, the league’s median Super Bowl participant has ranked second in regular‑season winning percentage, and 58% of Super Bowl teams entered the game with the best record in the league.
MLB’s top teams typically win about 60‑61% of their games, and the median World Series participant ranks fourth in regular‑season performance. Only eight of the 26 World Series clubs since 2013 held the league’s best record, a 26% rate versus the NFL’s 58%.
Implications for Fans and Stakeholders
The data suggest that an NFL franchise finishing outside the top three in winning percentage faces a steep uphill battle to reach the Super Bowl. Conversely, MLB clubs finishing well down the standings still possess a realistic path to a championship, as demonstrated by the 2023 Arizona Diamondbacks (13th in winning percentage) and the 2021 Atlanta Braves (12th).
These trends have practical implications for fans, owners, and broadcasters. The NFL’s structural features—such as a shorter regular season, a single‑elimination playoff format, and a scoring system that often produces high‑scoring games—contribute to the predictability. Meanwhile, baseball’s longer season and best‑of‑seven series format preserve greater uncertainty.
Looking Ahead
While the NFL’s dominance by a handful of teams may concern those who value competitive balance, the league’s popularity continues to thrive, bolstered by fantasy football, the Red Zone channel, and expanding gambling markets. Baseball, on the other hand, maintains a broader distribution of championship opportunities, which may appeal to fans seeking more unpredictable outcomes.
Stakeholders in both leagues will need to weigh these dynamics as they consider future rule changes, revenue sharing models, and fan‑engagement strategies.
