Game quality
What each result was worth beyond the score. Every play is graded by EPA (expected points added), then adjusted for who it came against: a defence's rating is what it allowed to everyone else that season, so a big day against a bad defence counts for less. Season views include playoff games.
Games
Adj margin = offence minus defence EPA per play after the opponent adjustment. Win exp = how often a team with that adjusted margin wins; a 55% win was a coin flip that landed. Win prob range = lowest and highest in-game chance, which is where blown leads and comebacks show.

Quarterbacks this week
Click a column to sort. Schedule = what the opponent adjustment added (+ = faced a tough pass defence). Turnover and sack EPA are what those plays cost; sacks are shared with the line.

Win expectancy is a logistic fit of wins on EPA margin over 6,036 completed games (it names the winner 86.5% of the time). These describe what happened; one game is not a forecast. Play-by-play credits the quarterback with every sack and dropback, so a bad line shows up in his numbers. Seasons 2016–2026, built 2026-09-14 01:25 UTC, from nflverse. Write-up:
