The same down-based success standard as passing success rate, applied to a player's carries.

Inputs: Down, distance, yards gained and touchdown on plays where this player was the ball carrier.

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.

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.
