As data analysis and NFL data becomes more and more available, information and analysis regarding flashy positions and plays constantly teach us new things about the game of football. While we have a pretty good idea of how the relationship between air yards and EPA works for instance, few analytical efforts have paid attention to the optimal kicking distance for a field goal. Kicking a field goal in the NFL is a very specific and straight-forward task, and KOE was built specifically to evaluate it as fairly as possible.
