Red Zone / Final 2 Minutes splits carry a real, disclosed field-position/clock coverage gap — see “Advanced Metrics Explained” below.
ADVANCED METRICS EXPLAINED (1)
Red Zone Splits
How a player performed once his team's offense (or the opponent's, for a defender) reached inside the 20-yard line.
Inputs: Every play on file within 20 yards of the goal line (`distance_to_goal <= 20`) this player was involved in. COVERAGE CAVEAT: true field position is only recorded for about a third of plays leaguewide, concentrated in FBS/FCS games -- a player whose games come from a source without it will show thin or missing red-zone splits even if he played plenty of red-zone snaps. This is a gap in the underlying play-by-play data, not a sign he didn't play there.
