too few snow games league-wide to say; QB rushing yards +43% in them
The line at the bottom of each card is the league-wide pattern for QBs (starters, 2005–25, each player vs. his own other games), for context against this player's own numbers.
Weather is the observation at the stadium's nearest NOAA station in the kickoff hour. Splits under 8 games are shown faded: a couple of blowouts move them a lot. Cold, windy and snowy games are also disproportionately late-season, at home in northern stadiums, and against specific opponents, so a difference here is a starting point, not a cause.
