Most football simulators hide a random number generator behind the scoreboard: run the same team twice and you get two different seasons. This one refuses. Draft your twelve starters and the simulation returns the record that roster mathematically deserves — the same team always finishes with the same result. If you go undefeated, nobody can say you got lucky.
▶ Simulate your first season — freeYour season is 17 regular-season games followed by three playoff rounds, mirroring a modern top-seed's path to a title. The simulator rates your roster position by position and converts that strength into wins along a calibrated curve. Two things matter more than everything else:
Position weight. Your quarterback counts 1.5× in the team rating. Edge rusher and cornerback count 1.2×. The other nine spots count evenly. This mirrors how the real league prices talent — and it means a simulator-savvy drafter budgets re-rolls for those three positions.
No compensating luck. There is no injury dice, no fumble variance, no schedule mercy. A 14-win roster wins 14. The only way to change the outcome is to build a better team.
The player pool spans eight decades — over 9,000 real player seasons across all 32 franchises. Raw numbers from 1965 and 2024 aren't directly comparable, so ratings are normalized within each era: a legend is measured against the elite of his own decade, then eras are balanced so no decade quietly dominates the simulation. A 1970s pass rusher next to a 2020s quarterback is a fair pairing, and the simulator treats it as one.
When the final whistle sounds you get more than a record. The report grades your offense and defense separately, so you can see precisely which unit left wins on the table — a 96-rated offense dragged to 16-4 by an 81-rated secondary is the most common autopsy. Each game in the 20-game reveal is derived from your roster too, so replaying the same team shows the same season story, loss for loss.
Because results are reproducible, every score is comparable. The seasons you create can be handed to a friend as a link — they draft from the identical spins and the better roster-builder wins, provably. And on the daily board, the entire world simulates against the same slate. A simulator with randomness can't offer that; this one is built on it.

Not in the outcome. Your twelve players fully determine the final record. Only the cosmetic order of the win/loss reveal is drawn from your roster's own seed, so even that replays identically.
More than 9,000 real player seasons from 1952 to today, organized into 189 franchise-era squads across all 32 teams.
A perfect 20-0 — seventeen regular-season wins plus three playoff wins. Fewer than one expert draft in two hundred reaches it. See the perfect season simulator page for what it takes.
