Challenges in Predicting Upsets: Lessons from Underdogs in Sports

Challenges in Predicting Upsets: Lessons from Underdogs in Sports

Published on 12/12/2024 13:35:01

As football fans, we watch thousands of games, and only a handful of those give us a memory for a lifetime. Of course, on top of our list are those when our favorite team won a title or just beat the local rival, but witnessing historical football upsets is often more exciting.

 

Even if we have never done a data-driven sports analysis, just based on our experience, we are aware that now and then there will be some underdogs in sports beating a top-level team like North Macedonia eliminating the European champion Italy from the 2022 World Cup Playoffs.

 

Still, there is no football predictions model that can come up with an assumption that a team like Leicester City would win the Premier League like the “Foxes” did back in 2016. Given that, one of the key lessons from football underdogs is that low-predictable events will happen no matter how impossible they may seem, and the real question is how we should analyze historical upsets and adapt them to predictive models.

 

What is an upset in sports?

One of the main reasons why we follow sports is competitiveness. However, there are many events when one team is an absolute favorite to win, and when things do not go as the majority expects, we call that an upset. A team is labeled as an underdog based on the team rankings, budgeting, history, recent form, injury report, and many other factors that should be taken into consideration when we make our betting tips. Again, no matter how detailed a statistical analysis in sport can be, there will always be events when David beats Goliath.

 

Historical Upsets Over the Decades

There have been numerous epic upsets in recent history, both in team and individual sports.

 

The English Premier League is widely considered the top football league in the world. Going into the 2015-16 season, only five teams have won the title since its foundation in 1992. The year before, Leicester City returned to the top tier of English football after ten seasons competing at the lower level. Out of nowhere, the “Foxes” had an impressive season, losing only three games and winning the league with a 10-point advantage over the closest one in the standings, Arsenal.

 

Back in 2009, Rafael Nadal arrived at the French Open as a winner of the last four editions. Going into the fourth round of the tournament, Nadal was on a 31-game winning streak and has never lost a match at Roland Garros. On the other side of the net was Robin Soderling, ranked No. 25 in the world, who had won a total of three ATP titles by that point of his career. Somehow, the Swede pulled out one of the greatest upsets in tennis history, beating Nadal in four sets.

 

In the first case, a team just built a chemistry that was able to beat all the talent in the league, and their consistency was unprecedented. In the second one, an inspired player showed up ready for the challenge and just refused to go down. In both instances, no betting tips could have seen that coming.

 

Why Predictive Models Struggle with Upsets

Sticking to a data-driven sports analysis when it comes to sports betting may be the right strategy for many. Still, over-reliance on historical data and trends may lead you to a dead end, so sometimes we should go with Bayesian models in sports since, at the end of the day, there is a human factor in every event.

 

Just like any other person, an athlete can have a bad day at work; there can be behind-the-scenes events that can impact the performance of an individual or a team, and often there are “black swan events” in sports on any level.

 

One of the greatest football games in history took place in the 1950 World Cup when the home nation, Brazil, faced Uruguay in the final in front of almost 200,000 fans. The Brazilians took the lead, but the visitors turned things around with a pair of goals in the second half, which many consider the greatest upset in sports history.

 

At the 1992 EURO, Germany was coming as a world champion, winning the trophy two years before in Italy, while Denmark failed to qualify but still found themselves at the competition after Yugoslavia was suspended. These two teams met in the finals, and it is still hard to believe how Denmark won that one.

 

Adapting Predictive Models to Account for Upsets

With the advancement of technology around us, sports betting also benefits from implementing AI predictions. You don’t need to be an expert to look at the team form, standings, and previous head-to-head matchups, but incorporating contextual variables like injuries and team morale can make the difference between a bet and a winning bet.

 

The use of dynamic data sources is what gives the advantage to AI predictions over anything we’ve seen before. Social media sentiment analysis, real-time performance tracking, the team schedule, and the distance covered between two games are all factors that make the difference, and using AI can bring us an advantage like we never had before.

 

Lessons for Teams, Bettors and Analysts

It takes a while to put all the pieces of a puzzle together and create a winning team, and even when it seems like we have a favorite to win a game or a competition, it all can come down in the blink of an eye.

 

Every collective faces its challenges, and every game demands a specific preparation. Keeping the same focus and form for an entire season is almost impossible, and that is when the bettors need to rely on their intuition. There is nothing better in football prediction than winning while going against the odds, so regardless of how reliable the date-driven models look, sometimes we should just trust our gut.

Sports betting is much more than math, so continual model refinement and recognition of unquantifiable factors have to be implemented as well.

 

The beauty of sports lies in its unpredictability

The predictive modeling in sports betting may seem like the right path when it comes to sports betting. Still, it comes with a lot of challenges. The beauty of sports lies in its unpredictability, and we should always keep in mind that the human element often trumps the numbers.
