Has any NFL team ever gone undefeated?
Once. Miami went 17-0 in 1972 — fourteen regular-season wins, two playoff wins and the title game, none dropped — and it has not happened again. New England came closest in 2007, winning all sixteen regular-season games before losing the Super Bowl to finish 18-1. That rarity is the whole point: most boards here fall short.
What do 17-0 and 20-0 mean?
Both are a perfect season. The modern NFL regular season is 17 games, so an unbeaten one is 17-0; add the three-round playoff and a perfect run to the title is 20-0. In this game a full run is those seventeen games plus the playoffs — win every one and the board reads a perfect record. Every seat contributes to the position-weighted team score, and one loss ends the run.
How do I build an all-time NFL team?
Each round spins one real franchise era — a city and a window of years, anywhere back to the 1960s — and lays out that squad with real season statistics on every card. You pick a player, choose his seat, and move on. Twelve seats later the season simulates week by week.
Which eras can I draft from?
Sixty years of pro football, city and years only — from the leather-helmet greats to last season’s contenders. Every player-season is rated on how good it actually was, against its own era, so a 1970s front seven and a modern spread offense meet on level ground.
Is this a 17-0 team generator?
Effectively, yes — each spin generates a real franchise era with its actual roster, and your picks build the team. It goes one step past a randomizer or filter: the season then simulates week by week, so the generator comes with a scoreboard. Build well and it reads 17-0.
Do I need an account?
No. Open it and play; your rosters and streaks live on this device rather than behind a login.
