FeaturesAuction draft values, calibrated to your league
Generic rankings tell you what a player is worth on average across every league. Auction Analyzer reads your league's own draft history and tells you what that player is worth in your draft room — where budget, team count, scoring, and how your managers actually spend shape every price. Here is everything the product does.
League-Calibrated ValuesPlayer Values Built From Your League's History
A two-phase engine turns your past auction drafts into a custom set of values for this year — not the same generic numbers every other league sees.
Market structure from your history
We read every auction draft your league has run and build a price for each positional slot — what QB1, RB2, WR3, and so on typically cost in your room — weighted across recent years so the structure reflects how your league spends today.
Current-year player mapping
This year's players are lined up against those slots in ranking order, so each player inherits a price that's calibrated to your league instead of a one-size-fits-all auction value.
Prices that match your draft room
Every other tool gives the same values to every 10-team, $200, superflex league. Auction Analyzer builds a market from your league's behavior, so a position your managers overpay for is priced like they overpay for it.
Settings-aware
Budget, team count, roster slots, scoring format, keeper rules, and superflex all feed the model. Change leagues or years and the structure adjusts to that league's settings.
Recalibrates as rankings move
Player rankings firm up as the season approaches. When the underlying data shifts, your values update with it, so the cheat you carry into the draft reflects the latest information.
Slot-by-slot pricing
See the full positional price curve — every QB slot, every RB slot — not just a single number per player. The curve is the backbone of every other tool in the workspace.
Connect Your LeagueConnect ESPN, Yahoo, and Sleeper Leagues
Link your league once and we pull its full settings, managers, and auction draft history automatically.
ESPN, Yahoo & Sleeper
Connect ESPN with secure cookie credentials, Yahoo through official OAuth, and Sleeper through its public API. We sync your league settings, managers, and full auction draft results from each.
Full multi-year history import
We walk each platform's season chain — ESPN's multi-year league id, Yahoo's renew chain, and Sleeper's previous-season links — to import your draft history back to the league's beginning, not just last year.
Cross-platform league linking
Moved your league from one platform to another over the years? Link those leagues together so their combined history feeds one continuous market — Yahoo years and ESPN years calibrating the same valuations.
Manager tracking across seasons
Managers are tracked as people, not team names. A manager who renames their team or switches platforms is still the same owner, so spending tendencies follow them across every season.
Automatic player matching
Players are matched to a universal identity built from nflverse data, so the same player lines up correctly across platforms and seasons even when names are spelled differently.
Secure, read-only connections
Credentials are stored encrypted and never shared or shown back to you. We only ever read your league data — Auction Analyzer never makes changes to your league on any platform.
The Market PageYour League's Auction Market, Adjustable
The price of every positional slot and the spending behind it — with controls to model how the market shifts.
Positional slot prices
What each slot costs — QB1, QB2, RB1, RB2 — derived from your draft history and weighted across recent seasons. The full curve, laid out position by position.
Position allocation controls
Adjust how much of the league's total spending flows to each position and watch the slot prices recompute. Allocations are league-wide shares, so the number describes the whole league, not one team.
Carve-outs for dead money, K & D/ST
Account for budget tied up in kickers, defenses, and unspent money so the dollars that actually chase skill players are priced accurately.
Preview before you commit
Try out allocation and carve-out changes in a preview, see the effect on every price, and commit only when the structure looks right for this year's draft.
Recalculation tracking
When you commit a new market, the rest of your workspace knows. Affected strategy values are flagged for review rather than silently overwritten.
See the historical baseline
Every adjustment is anchored to what your league has actually done, so you're tuning a real market rather than inventing one from scratch.
Positions Deep-DiveCompare Every Player Across Every Source
A position-by-position table that puts your league-calibrated value next to the major reference sources, so mispricings jump out.
Multi-source comparison
See each player's league value alongside FantasyPros rankings, your own expert or custom rankings, and platform draft-room values (AAV) — all in one row.
Consensus & deltas
A blended consensus and a signed delta against your chosen baseline make it obvious where a player is cheap, expensive, or roughly fair in your league.
Spot mispricings
The whole point: find the players your league's market values differently than the field, so you know where the value and the traps are before draft night.
Target & avoid tags
Tag the players you're chasing and the ones you're fading. Tags follow that player everywhere they appear in your league workspace.
Per-position notes
Leave notes on each position that persist for your league — your read on the position's depth, sleepers, or who to wait on.
Bring your own rankings
Upload custom rankings to use as your baseline. Your numbers slot into the comparison so the values reflect how you see the player pool.
Strategy BuilderBuild Your Draft Plan Slot by Slot
Turn your values into a plan: name the players you want, set the budget you'll spend, and stay flexible when the draft doesn't cooperate.
Ideal mode
Name the specific player you want for each roster slot and build a complete dream-team plan with a running budget.
Tier mode
Target a band of tiers per slot instead of one name, so on draft night you grab the best available player in your range rather than reaching for one guy.
Cornerstones & targets
Mark the anchor picks you're committed to building around, line up backup targets and candidates for each slot, and keep your fades visible throughout.
Custom dollar overrides
Disagree with a value? Override it. Your number sticks, and the running budget reflects the plan you actually intend to execute.
Change review
When the market or rankings shift, the rows tied to affected players are flagged with the old and new value side by side, so you can adopt the update or keep your number — one row at a time or all at once.
Multiple plans & notes
Build several strategies, copy one as a starting point for another, and leave notes per position group so the reasoning behind the plan lives with it.

Multi-year view
