Can you go 82-0?
Draft an all-time NBA starting five — spin a team reel and an era reel, pick your five, and let the engine find every hole in your lineup. Going undefeated is achievable. It's also brutally hard.
No other version explains why your five wins or loses.
Most all-time lineup builders just add up box-score averages. That gets it backwards.
Five 30%-usage stars, one basketball — on paper it never breaks down.
That's backwards.
Curry, Jordan, LeBron, Giannis, Jokić — and it still docks them −13.2 for usage overload.
The engine gets it right.
One basketball can't feed five ball-dominant stars. Our engine knows that. A box-score adder doesn't.
An orange TEAM reel and a violet ERA reel land on a franchise and decade. Lock one and re-spin the other to hunt the player you want.
Browse that era's roster and slot a player at each position — PG, SG, SF, PF, C. Eligibility is enforced: five point guards is not a lineup.
The engine simulates all 82 games and returns a record, a letter grade, and a plain-English breakdown of what helped and what hurt — and in Daily mode, ranks you on a server-verified leaderboard.
An engine that plays real basketball
SweepSzn is fit to 1,170 real NBA team-seasons — not hand-tuned. It tracks finite possessions, era-normalizes every player, gives defense equal weight with offense, and scores spacing and fit. The result punishes exactly the lineups a box-score adder adores — the difference between a 74-win team and a 40-win one.
