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).
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.
What is "garbage time"?
A 7-tier rule (bigger lead required as the clock runs down) that flags plays happening in a game that is no longer competitive -- e.g. a 30+ point lead right after halftime, or a 12+ point lead inside the final 3 minutes.
Inputs: Quarter, game clock, and the score of both teams at the time of the play. Garbage-time plays are not thrown out -- they count for 35% of a normal play in every "garbage-time-adjusted" figure, so a player who pads stats once a game is decided shows up as such rather than being invisible.
