FIVE YEARS OF BEST BALL MANIA  ·  THOUSANDS OF SIMULATED SEASONS  ·  ONE SCORE
You drafted your book — but is it actually good? And now that the season's live, which teams are advancing and which are quietly sinking it? That's what the data answers. We borrow concepts from finance to grade every team, track your whole book through the season, and tell you exactly where you stand — every week.
What we measure

Three scores do the work.

No dashboards to decode. Every roster and every player reduces to a score you can act on.

Build Score
How every roster was built — draft capital, positional structure, stacks, and breadth, all graded against the winning shape.
0–100 · PER TEAM
Exposure Score
How your whole book is spread — bet-sizing by round, player availability into the finals, and how many truly independent title shots you hold.
0–100 · YOUR BOOK
Upside Score
The ceiling you drafted — how high your teams can score, how often they spike, and how cheaply you bought it.
0–100 · 50 = THE MARKET
