Keep the official result
We never rewrite Sleeper's standings and call the alternative “the real table.” Official wins decide the league. Effective records and swaps are comparison lenses that explain how the route to that table unfolded.
Sleeper-first learning centre
Fantasy football numbers, explained without the fog
A win is a win, but it is not always evidence of a good week. These guides explain how Was It Luck? separates results, decisions and schedule context using public Sleeper league data.
Fantasy football compresses a complicated season into a simple record. That record matters—it decides standings and playoff places—but it cannot tell you whether a manager scored well and met the only opponent capable of beating them, or scored poorly and survived because their opponent had an even worse week. Was It Luck? keeps the official result intact and adds the missing context.
Sleeper is our primary provider because its public API exposes league settings, rosters, weekly matchups and season links with enough structure to reproduce the analysis. We do not pretend that one statistic proves who is the best manager. Instead, each metric answers a narrower question and states its assumptions so league-mates can decide what the result means.
Start with the question your league is arguing about
GUIDE 01 · PERFORMANCE
Was the record lucky?
Learn how weekly all-play comparisons create an effective record, how normalized effective wins work, and why “stolen wins” describe schedule outcomes rather than cheating or managerial intent.
Read the effective-record guide → GUIDE 02 · SCHEDULEWhat if we swapped schedules?
See what a Calendar Swap changes, what it deliberately keeps fixed, and how to read the counterfactual without claiming it is a perfect replay of the season.
Read the schedule-luck guide → GUIDE 03 · RIVALRIESWho is your real nemesis?
Follow a Sleeper league across seasons, understand head-to-head samples, and interpret nemesis, easiest-opponent, streak and margin records without overrating one memorable upset.
Read the league-history guide → GUIDE 04 · LEAGUE SETTINGSIs it PPR, Half PPR or Standard?
Compare reception scoring with the rest of the scoring system, learn how Was It Luck? classifies Sleeper leagues, and understand why unusual reception values are honestly labelled Custom.

Compare like with like
Analysis stays inside the same league and week wherever possible. That controls for scoring settings, player pool, NFL bye weeks and the scoring environment better than comparing raw totals from unrelated leagues.
Show the caveat
Fantasy outcomes mix lineup choices, injuries, waivers, trades, opponent timing and randomness. A useful metric names the piece it measures and avoids claiming the rest disappeared.
A practical way to read your league report
- Begin with official wins, losses and points. They describe the season that actually happened and provide the baseline for every other comparison.
- Add weekly performance context. Effective records show how frequently each score would have beaten the rest of that league in that exact week.
- Inspect opponent timing. A Calendar Swap tests how two teams' records change when their weekly scores meet each other's opponents.
- Zoom out across seasons. History and rivalry records reveal whether a supposed nemesis is a durable pattern or one dramatic matchup.
- Check the settings before comparing accounts. Reception scoring and custom bonuses change the scale and distribution of points.
