If you throw the word “luck” into a sports conversation you’re gonna anger some people because people don’t like to ever chalk up their own success or their team’s success to anything apart from their own skill, worthiness and merit. What we usually refer to as “luck,” however, is not meant to detract from one’s merit. It’s more about outcomes that were not necessarily predictable or expected given all of the known variables.
Thing is, we really don’t have a concise and compact word that captures the notion of “unreasonably underperforming or unreasonably outperforming one’s statistical expectations,” so the word “luck” is about as good as we can do. Sorry if that offends, but focus more on what we’re getting at when we talk about sports luck and less about how you feel about the concept of luck in general, OK?
With that in mind, know that, according to Rob Arthur of FiveThirtyEight, the Cubs have been the unluckiest franchise in baseball history in terms of turning success into championships. Given how much they’ve won over the years, they should have had six or seven championships and not the two they have (with none for 108 years, of course).
The luckiest? The Yankees. While they have obviously been immensely talented throughout their history, the numbers suggest that they should “only” have 19 or 20 World Series titles. They have 27. They’d still have the most if everyone performed at their level of statistical expectations, but their 16-title lead over the next most successful World Series team — the Cardinals — should not be as great as it is.
