Passing yards and the tyranny of game script

Passing yards is the most-taken NFL stat and the one most tied to something outside the player's control: whether their team is winning.

Game script, explained once

Football teams pass when they need yards quickly and run when they want to consume clock. A team that's behind throws more, because throwing stops the clock and covers ground faster. A team that's comfortably ahead runs more, because running does the opposite.

So a quarterback whose team trails for most of an afternoon accumulates attempts almost automatically, sometimes against a defence content to allow short completions while protecting the sidelines. A quarterback whose team leads throughout may put up a modest number and have played excellently.

This inverts the naive read. "I think this team wins comfortably, so I'll take More on their quarterback's yards" is a bet that quietly works against itself.

What to look at instead

That last one is under-appreciated. If a team's lead back is out, the pass-run balance shifts before the game even kicks off.

Who is available to throw to

A quarterback's yardage depends on receivers getting open, and a depleted receiving corps compresses the whole passing game. A missing primary target does not simply redistribute — defences can commit more attention to what is left, and throws get shorter.

The inverse is a genuine edge. A receiver returning from injury restores something the line may have been set without, and that information usually arrives in the days before kickoff rather than on the morning of the game.

Weather is real, and mostly about wind

Rain and cold get talked about most; wind matters most. Sustained high wind disrupts the deep passing game specifically, which is where yardage comes from in chunks. A team can complete plenty of passes into a stiff wind and still finish well short of a normal yardage day.

Cold on its own does less than people assume. A dome removes the question entirely — worth knowing when the line looks like it's priced for weather that won't exist.

Garbage time counts

Yards accumulated late in a decided game count exactly the same as yards in a tight fourth quarter. A quarterback whose team is buried can pile up production against a defence playing soft coverage and running the clock out.

This is a genuine source of edge for More, and a genuine risk for Less. If you take Less on a quarterback, you're also implicitly hoping the game doesn't get away from their team in a way that opens the floodgates.

The reframe

Don't ask whether the quarterback plays well. Ask how many meaningful pass attempts this game produces for them, and how far each one is likely to travel.

Both of those are mostly questions about the game, not the player — which is why the best NFL reads usually start with the matchup and only then arrive at the name on the card.
