About 20-0

20-0 is a free browser game about one of the best arguments in football: who really belongs on a perfect team?

What the game is

Every round, a slot machine lands on a real NFL team and era — the 1985 Bears, the 2007 Patriots, the 1994 49ers — and you pick one player from that roster to fill a position. After twelve picks we simulate a full 20-game season, grade your team from F to a perfect S, and drop your result on a daily leaderboard. There are two ways to play: Classic, where every player's rating is visible, and Gridiron IQ, where the numbers are hidden and you draft on football knowledge alone.

Where the numbers come from

Player ratings are 20-0 editorial game values, not official NFL grades. Historical stat lines are being revalidated source by source after a July 2026 audit found errors in the original dataset; they should not be treated as an official record. Ratings, historical fields, and simulated results are kept separate, and confirmed factual corrections are published.

Who makes this

20-0 is built and edited by Marcus Bennett, who grew up arguing about all-time rosters and got tired of never being able to settle it. It started as a way to turn those debates into something you could actually score, and grew into the daily game it is today.
