The goal: Draft a fantasy football team capable of a perfect, undefeated 17-0 season. You're picking real players' real seasons (1999–2025) and trying to build the highest-scoring, most well-rounded roster possible. Scores use real season fantasy points (PPR).
Play at 17-0.sleeper.com or in the Sleeper app.
How to Play
1. The Roll
Each round, you're assigned a random NFL team and season (1999–2025). Draft one player from that team/season into an open roster slot. There are seven rounds — one per roster spot.
2. The Roster
Your starting lineup is 1 QB, 2 RB, 2 WR, 1 TE, and 1 FLEX (any RB/WR/TE).
Desktop: drag a placed player to another eligible slot to rearrange.
Mobile: tap a player on the roster bar to move them.
For example, you can shift a flex RB into an open RB slot to free up the flex for a receiver.
3. The Re-rolls
You get one team re-roll and one year re-roll for the entire game, available on the draft screen.
4. Optional: Connect your Sleeper username
You can add your Sleeper username before you start to attach your run to your account. This is optional.
Chemistry
Each player brings their real fantasy points per game (FPPG). Pairs of players earn ⚡ chemistry that boosts FPPG, and each bonus applies to both players in the pair:
Bonus | Connection |
+1 | Past Teammates |
+1 | Same Draft |
+2 | Same Team |
+2 | Same College |
+1 | Elite connection (bonus) |
+2 | Legendary connection (bonus) |
Elite and Legendary connections are a curated list of great real-life duos. A more connected roster scores higher than a collection of unconnected stars.
Scoring
Total FPPG = Team FPPG + chemistry.
Each starter brings their real season FPPG (PPR).
Chemistry between pairs adds to each player's FPPG.
The higher your total score, the better your projected record.
A perfect 17-0 takes an elite lineup with real chemistry on top — going undefeated is the hardest stretch by far.
