NEW YORK—According to a report released Tuesday by the SportsBusiness Journal, not all NFL teams are collecting player data. “Our findings indicate that the vast majority of NFL teams are not actually collecting player data,” said lead researcher David Carroll, adding that the report also suggests that the vast majority of NFL teams are not analyzing player data. “It’s as if there’s a group of people in charge of collecting data, but no one actually knows what they’re doing.” Carroll went on to say that the report also confirms that “almost none” of NFL teams are actually using player data.
