A multi-dimensional analysis of NFL red zone efficiency

Red zone efficiency often characterizes high-performing offenses in the National Football League (NFL) because it can change the momentum of a competitive game. To succeed in red zone possessions, it is generally believed that teams must be effective in play design, quarterback proficiency, and strategic use of team personnel. These factors can be studied using full play-by-play analysis of the expected points before and after a play, gathered from Pro Football Reference. Central to this exploration is the question of what strategies can be employed to maximize red zone efficiency. We hypothesized that utilizing a conservative style of play is positively associated with red zone efficiency. In our analysis, we defined a conservative style of play by dividing the number of fourth-down and third-down passing attempts by the total number of red zone plays. We performed several analyses by leveraging NFL Savant and Pro Football Reference data and examining correlations between red zone efficiency metrics and team success. Our research revealed that while aggressive play calling was not statistically significantly correlated with the red zone efficiency metric, this style of play showed a strong negative relationship with expected points delta, defined as the change in expected points from before to after a play. This supported our hypothesis that increased red zone efficiency was achieved through a more conservative style of play. The results from this study offered insights to enhance team efficiency by illuminating offensive strategies and tactics that contributed to red zone success.
