The records for this study come from multiple seasons of the NFL during which different systems were used to calculate and record a player’s orientation. Within a play, and across plays in a game, an individual player’s orientation will be recorded consistently, but the “geography” (i.e. the actual direction the player is facing) of the reported orientation may not match the “geography” of the direction variable in the same play. For those players that participated in multiple seasons, the geography used to record the orientation variable is not consistent across seasons. The orientation variable can be used to characterize how much a player is turning or pivoting during the course of a play. The “geography” of the direction variable does remain consistent across the study horizon.</p>",
