Three steps from a CSV to a data-backed read on your portfolio — and a personalized plan to win the big one.
No account, no manual entry, no re-typing a single roster. Export the CSV your platform already gives you, drop it in, and every team you drafted is in the system in seconds. Underdog is live today — DraftKings is next.
Your book stays private — we never share it, and you don't need to create an account to get scored.
We run your real rosters through the same engine that studied five years of Best Ball Mania, then hand it back as three levels of analysis — the player, the team, and the whole portfolio — each built to answer one question.
Every player you drafted, scored on upside relative to ADP — his real ceiling, not his floor. See where you are over- and under-exposed, and where your exposure and a player’s upside disagree.
Every one of your teams gets a Team Upside Score, 0–100, where 50 is an average roster drafted at ADP. Higher means further above the field. See your Draft DNA — how you build by position — and your stacks.
Your whole book in one view. The headline is Effective Teams — how many of your entries are truly independent title shots after correlation takes its cut — plus exactly where you’re over-correlated.
A score tells you where you stand. Your Recommendations tells you what to do about it. Set how many teams you’re building this season and we show what that book buys you — then hand you the highest-leverage, most-diversifying targets to get there.
Every recommendation is tuned to your book — designed to add independent upside where you’re thin and diversify away from your over-concentrated bets.
Score every team you drafted and get the exact targets to draft next — in about a minute.
