All-Play Record and Luck in Fantasy Football, Explained
Updated October 13, 2026
Every fantasy league has a manager who scored the second-most points in the league and missed the playoffs, and another who backed into a title. Your weekly matchup is a coin flip you don't control: you can't play defense. All-play record takes the schedule out of it, and the gap between your real record and your all-play record is the closest thing fantasy football has to a luck number.
What is an all-play record?
Your all-play record is what your record would be if you played every other team every week. In a 10-team league, each week counts as 9 games:
- Highest score of the week: 9-0.
- Second-highest: 8-1.
- Lowest score: 0-9.
Add up the weeks and you get a season (or all-time) all-play record. It rewards only one thing: how many points you scored compared with everyone else that week.
Luck = win % minus all-play %
Turn both records into a winning percentage and subtract:
Luck = actual win % − all-play win %
- Positive luck: you won more than your scores deserved. Your opponents tended to have bad weeks against you.
- Negative luck: you scored well and lost anyway. The schedule did you no favors.
- Near zero: your record is about what your scoring earned.
A worked example
A 10-team league plays a 13-week regular season. Two managers:
| Manager | Record | Win % | All-play | All-play % | Luck |
|---|---|---|---|---|---|
| Manager A | 5-8 | .385 | 78-39 | .667 | −.282 |
| Manager B | 9-4 | .692 | 55-62 | .470 | +.222 |
(13 weeks × 9 opponents = 117 all-play games.) Manager A beat two-thirds of the league in an average week and finished 5-8. Manager B scored below average and went 9-4. Multiply all-play % by games played and you get expected wins: Manager A "should" have won about 8.7 games, Manager B about 6.1.
What luck can't tell you
- Lineup decisions aren't luck. If you left 40 points on your bench, that's on you, and it's already baked into your score.
- Small samples swing. One season is 13 or 14 games. Over five or ten seasons, luck tends to drift toward zero, which is exactly why all-time numbers are more telling than one year.
- It doesn't count the playoffs. Titles are decided in a few single-elimination games. A strong all-play team can still go out in the first round.
Related numbers worth knowing
- Points against (PA): how much your opponents scored against you. High PA per game is the usual cause of negative luck.
- Points for per game: the simplest measure of team strength, and comparable across seasons with different schedule lengths.
- Average finish: where you end up after the playoffs, averaged across seasons. More in the stats glossary.
