Receiving Success Rate
The same down-based success standard, applied to a player's targets (thrown to him, complete or not).
Inputs: Down, distance, yards gained and touchdown on plays where this player was the targeted receiver.
3rd Down Splits
How a player performed specifically on 3rd down plays this season -- success rate, touchdown rate, and the underlying counting stats, isolated from every other down.
Inputs: Every play on file where down = 3 and this player was involved (passer, rusher, receiver, or a tackle/sack/INT/fumble recovery on defense).
4th Down Splits
The same idea as 3rd Down Splits, isolated to 4th down plays -- the highest-leverage down in football.
Inputs: Every play on file where down = 4 and this player was involved.
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.
Final 2 Minutes of a Half
How a player performed in the last two minutes of either half -- the clock-management, high-pressure stretch at the end of the 2nd and 4th quarters.
Inputs: Every play on file in the 2nd or 4th quarter with 2:00 or less on the clock this player was involved in. Same field-position/clock coverage caveat as Red Zone Splits above -- roughly a third of plays leaguewide carry a usable clock reading, concentrated in FBS/FCS games.
