How FantasyDomain Values Dynasty Assets

Every number should be checkable: what it was built from, which format it assumes, and when it last moved. No black box, no hand-waving.

1. League audit context

The differentiator is the league layer. A roster audit should understand scoring format, contracts, contender windows, depth, schedules, and manager incentives before it assigns a value or line. A player is not worth the same thing in every league.

2. The baseline model

Values start from a documented model rather than a gut feeling: projected production above a positional replacement level, adjusted by an age curve and discounted for future seasons. That model is written out in full on the how values are calculated page, and it is what keeps the board internally consistent instead of swinging on the latest highlight.

Be clear about where the current board comes from: it is a curated set of baseline values, versioned and dated, not a number recomputed on every page load. The illustrative sample board shipping today is marked as such on every tool.

3. Market inputs

Models miss context. Real trades, ADP movement, and aggregated community rankings are the obvious next layer, and the gap between the market and the model is usually where the edge is. None of that is ingested today — no trade feed, no ADP feed, no rankings feed. When it lands, the intent is to show the disagreement rather than quietly average it away.

4. Format multipliers

A player isn’t worth the same in every football league, so we don’t pretend otherwise. Two toggles adjust the board. Superflex — a flex slot you’re allowed to fill with a quarterback — roughly doubles QB value (1.7× for a streamer, up to 2.15× for an elite arm) to reflect that scarcity, and lifts rookie firsts 18% because a pick can become a quarterback. TE-premium adds 35% to tight ends. Strict 2QB leagues, where two quarterbacks are mandatory rather than optional, sit slightly above the Superflex setting — use it as the closest available approximation.

5. Arena-ready probabilities

Rankings are the starting point, not the end product. FantasyDomain is building toward a prediction surface a league can actually use: matchup lines, audit notes, and transparent probabilities tied to your own league's context. None of that ships today — what ships is the valuation model above and the free-play market tools built on it.

The principle is fixed regardless: a number nobody can inspect is a guess with a decimal point. Any league-approved side challenge should rest on a published model people can check, not on a black box. Public markets are free-play only, have no cash value, and have no connection to real securities, sports betting, or wagering.

Dated snapshots when boards go live

Official boards should be dated and versioned, so you can see when a number changed and why. We would rather show you a value that moved than quietly pretend it never did.

What this isn’t

It isn’t a guarantee, and it isn’t advice dressed up as certainty. Fantasy is a game of probabilities. Our job is to give you a defensible starting point and the reasoning behind it — then your league makes the call.
