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.

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.

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.
