The practice of estimating the percentage of Daily Fantasy Sports (DFS) contests in which a National Football League (NFL) player will be selected is a critical component of successful lineup construction. These estimations forecast how popular a particular player will be among other DFS participants. For example, if a projection indicates a player will be in 30% of lineups, it suggests that approximately 3 out of every 10 entries will include that player.
Understanding the expected popularity of players is vital for differentiating a DFS lineup. A lineup consisting solely of highly-owned players is less likely to win large-field tournaments due to the shared prevalence of that specific player combination across numerous entries. By incorporating less popular, yet potentially high-performing players, a lineup can gain a significant edge. The development of these predictive models has evolved alongside the DFS industry, becoming increasingly sophisticated with access to more data and advanced analytical techniques. This evolution has led to a greater focus on nuanced game theory in lineup construction.
