When we judge the quality of a player, we tend to look back on past performance. That can be great as a retrospective, but past performance isn’t always the greatest indicator of future success. Knowing the numbers is good, but knowing which numbers can be volatile from year-to-year is better. A lot of that centers around touchdowns. Whether it’s quarterbacks, running backs, or wide receivers, touchdown rates typically regress to the mean from one season to the next. This is a useful thing to know for fantasy because touchdowns are king, the biggest point getters. Regression to the mean works both ways, even though the term is mainly used in a negative light.
