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).

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.

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.

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.
