Build Score

56build score

Build Score grades how you built your teams — the shapes and stacks the data keeps rewarding. It breaks into four measured signals, each scored against the field. For each one: what the research says, where your book lands, and the one number for how well they line up.

Draft Capital

38vs field

Research says how each number of early picks (through Round 6) has actually advanced in Best Ball Mania. The number is what research says; the bar is where your teams land. Line them up: are your bars on the green rows?

Across 2023–2025, early RB carries the steepest advance edge — the curve peaks around 3–4 RBs by Round 6.
WR is a gentler curve: the field's best-advancing count sits near 3 WRs, tailing off on either side.
Every early QB or TE costs advance rate — the field advances most with zero of each through Round 6.
Because the field itself under-drafts early RB, the sweet spot is where an edge is still available.

+1.7ppadvance captured

Advance captured is the one number for how well your build lines up with the research: each count's advance rate, weighted by the share of your teams there. Your early-capital shape earns +1.7pp of advance vs the field. Most of the headroom is RB.

Advance rates: actual Underdog Best Ball Mania results, 2023–2025 — the share of entries that reached the playoffs at each build (field average 16.7%). Faded rows are <500-entry samples.

Your takeawayYour book clusters at 2 RB / 3 WR early. On RB you sit just below the 3–5 sweet spot — the biggest lever in the whole metric. On WR you land right in the spot. QB and TE both sit exactly where the research wants them.

Lineup Depth

56vs field

Lineup Depth values your finished QB-RB-WR-TE shape by how often that exact build has advanced in Best Ball Mania 2023–25 — the positional balance a lineup card can't show you, scored.

Winning final builds cluster tightly at 5 RB / 3 TE.
The 3-5-7-3 shape has the highest advance edge (+2.3); 2-6-8-2 the worst (-1.8).
Drifting from 5-RB to 6-RB (or 3-TE to 2-TE) has cost ~2 pts of advance rate every year.
It's a small move with a big swing — a single roster slot moves you between rungs.

+0.7ppadvance captured

Same idea as Draft Capital: each final shape's advance-rate edge, weighted by the share of your teams that built it. Your shapes earn +0.7pp of advance vs the field, out of a +2.3pp ceiling (the 3-5-7-3 build). Nudging your weaker-rung teams up the ladder is the lever.

Your takeaway30 of your teams hit the +2.3 winning shape (3-5-7-3), but 26 sit on the -0.3 (2-6-7-3) rung — trimming a 6th RB or adding a 3rd TE on those nudges them up the ladder.

Stack Quality · Regular Season

56vs field

Research says teams that stack their QB with his own pass-catchers advance at a higher rate. Each row is a stack pattern, how much the field runs it, its advance-rate lift, and the share of your teams that use it.

The two patterns that carry real lift are the broad ones: any pass stack (+2.8pp) and QB + WR (+2.5pp).
Deeper patterns — QB + WR + TE, QB + 2 WR — add only a fraction of a point on their own.
A QB + RB pairing barely moves the needle (+0.3pp) — that pairing hardly correlates.
Presence is table stakes; the separation is in stack depth and quality, not whether you stack at all.

+2.8ppadvance captured

Advance captured mirrors Draft Capital. You run a pass stack — the umbrella pattern worth +2.8pp — on 100% of teams (field 92%), capturing its full lift. You're maxed on presence; the remaining edge is stack depth, not whether you stack at all.

Your takeawayYou run a pass stack on 100% of teams and QB+WR on 100% — above the field on every pattern. You're maxed on presence; your remaining regular-season edge is adding depth to the stacks you already have.

Stack Quality · Playoffs

66vs field

This blends your regular-season stack spread with your Week-17 game stacks — same-team catchers plus opposing bring-backs — weighted 65% toward the finals. One shared blow-up in the title week is a six-figure score.

Stacking one team is table stakes; titles come from covering several correlated game environments in the finals.
Week-17 is weighted about 65% of this score — the week that actually pays.
A game stack — your QB + catchers + the opposing bring-back — covers the whole game environment.
Coverage value climbs to about 6 finals game-stacked players, then plateaus.
The sweet spot is 4–7 finals game-stacked players per team.

7.2avg finals game-stacks

Playoffs is a coverage signal, not a field advance-rate table — so its summary is where you land, not a captured pp. Your book averages 7.2 finals game-stacked players, right at the top of the 4–7 sweet spot; 48 of 117 teams sit inside it and most of the rest are just above.
