Fantasy Player Valuation Methods: ADP, VBD, and Projected Points
Three frameworks sit at the center of nearly every serious fantasy draft decision: Average Draft Position, Value Over Baseline Differential (commonly called VBD), and projected points. Each one answers a different question about a player's worth, and understanding how they interact — where they agree, where they conflict, and why — separates managers who draft by feel from those who draft by design.

Definition and scope
Average Draft Position is the mean pick number at which a player is selected across a large sample of real drafts. Platforms like ESPN, Sleeper, and NFFC track ADP from thousands of completed drafts and publish the aggregated results. It functions less as a projection and more as a market price — a measure of collective expectation.
Value Based Drafting, introduced by fantasy analyst Joe Bryant at FootballGuys.com in the early 2000s, reframes player value not as raw output but as surplus production above the replacement level at each position. A player's VBD score is calculated as their projected points minus the projected points of the baseline player — typically defined as the last starter rostered in a standard league — at the same position. A running back projected for 280 fantasy points in a 12-team league where the RB24 is projected for 160 points has a VBD of 120. A wide receiver projected for 240 points against a WR36 baseline of 130 points has a VBD of 110. The running back is more valuable by this method, even though his raw point total is higher only by 40.
Projected points are the foundational input: statistical forecasts translated into fantasy scoring. Sources range from site-specific models (FantasyPros consensus, ESPN projections) to sharp independent operations like PFF (Pro Football Focus) and The Athletic's beat reporters who provide usage signals that feed quantitative models.
The scope of all three methods covers redraft formats primarily, though dynasty draft strategy requires additional adjustments for age curves and multi-year windows.
Core mechanics or structure
ADP mechanics. ADP is computed as a rolling arithmetic mean of pick numbers. A player drafted at picks 8, 11, and 7 across three drafts has an ADP of 8.67. Sample size matters — ADP figures drawn from fewer than 200 drafts carry substantial noise, and early-preseason ADP (drafted in May or June) reflects far less informed market consensus than late-August ADP just before rosters lock.
VBD mechanics. The formula is straightforward:
VBD = Player Projected Points − Baseline Player Projected Points (same position)
Baseline selection is the contested variable. Three baseline conventions exist:
- Last starter: The last player at that position who would be a weekly starter across all league rosters (e.g., RB24 in a 12-team, 2-RB league).
- Last drafted: The last player likely to be drafted, regardless of starter status.
- Replacement level: A waiver-wire calibration point — the best player available for free on any given week, typically approximating the RB36 or WR48 in standard leagues.
Each baseline shifts the resulting rankings. Replacement-level baselines, championed by the analytics community around sites like RotoBaller and numberFire, tend to depress the relative value of elite positions and elevate scarce ones — a dynamic explained further in the value over replacement player framework.
Projected points mechanics. Projections are built from volume inputs (carries, targets, snaps), efficiency rates (yards per carry, catch rate, touchdown rate), and schedule strength. PFF's projection models, for example, weight positional snap share as one of the highest-correlation predictors of fantasy output.
Causal relationships or drivers
ADP is caused by projections and VBD assessments — it is the downstream output of market participants applying (or misapplying) both frameworks. When a consensus projection for a running back rises, his ADP tightens within days on platforms with active draft activity.
Projected points are caused by team context: offensive line quality, target distribution, coaching scheme, and injury history. An offensive coordinator who ran 14-personnel (1 receiver, 4 tight ends) in the prior season affects tight end and running back projections differently than a pass-heavy spread coordinator would.
VBD scores are causally sensitive to two inputs: the player's projection and the baseline player's projection. A change in either moves the VBD independently of the other. If a baseline RB24 suffers a training camp injury and his projection drops from 160 to 140, every running back above him gains 20 VBD points without their own projection changing at all. This interdependency is what makes positional scarcity a live drafting concern rather than a theoretical abstraction.
Classification boundaries
The three methods occupy distinct analytical categories:
| Method | Type | What it measures | Primary input |
|---|---|---|---|
| ADP | Market signal | Collective draft behavior | Aggregated draft data |
| VBD | Relative value score | Surplus above replacement | Projected points + baseline |
| Projected Points | Absolute forecast | Expected raw output | Statistical modeling |
ADP and VBD can diverge significantly at tight end, where positional scarcity compresses into 2–3 elite players (Travis Kelce-tier, in the parlance of the fantasy community) while the replacement level collapses sharply. The market often ADP-prices a top-3 tight end below their VBD ranking because managers anchor to positional convention — a known systematic bias.
Projected points and VBD can also diverge: a quarterback throwing for 380 projected points may have a lower VBD than a running back projected for 240, because the quarterback baseline is far higher (the QB12 in a single-QB league is typically projected around 300 points, leaving only 80 VBD points for the elite QB versus potentially 120+ for the elite RB).
Tradeoffs and tensions
ADP as a mirror vs. a guide. Using ADP as a draft guide creates a circularity problem: if every manager drafts by the same ADP, the market never corrects its own mispricings. ADP is most useful as a reference point for identifying divergence — cases where a manager's projection model assigns meaningfully higher value than the market consensus, which constitutes a draft strategy edge.
VBD's sensitivity to projection quality. VBD is only as accurate as the projections that feed it. A 10% error in a baseline player's projection propagates upward to every player at that position. Managers who treat VBD outputs as precise rather than directional overfit to projection noise.
Projected points in non-standard scoring. Raw projected points are format-specific. A tight end projected for 900 receiving yards is worth dramatically more in a league awarding 1.5 PPR for tight ends (a modifier used on platforms like Sleeper) than in a standard 1-PPR league. Failure to adjust projections to actual scoring system settings is one of the more common and consequential draft-room errors.
Recency bias in ADP. ADP reacts to news — a single beat reporter's training camp observation can move a player's ADP by 8–12 spots within 48 hours on active platforms. This responsiveness is a feature when the news is signal; it is a liability when the news is noise.
Common misconceptions
Misconception: Higher projected points always means higher draft value. Not true across positions. A quarterback projected for 340 points may be a worse pick in Round 3 than a running back projected for 230, because the baseline QB12 is projected at 295 (VBD: 45) while the baseline RB24 is projected at 155 (VBD: 75).
Misconception: ADP is predictive. ADP is descriptive. It describes where the market placed a player historically. In formats where managers are using data from prior months, early ADP can embed stale injury information or outdated depth chart assumptions that have since changed.
Misconception: VBD works the same across all league sizes. In a 10-team league, the RB20 is the baseline; in a 14-team league, it shifts to RB28. The entire VBD rank order reshuffles because baseline projections change. A player optimal in a 10-team context may be dramatically undervalued or overvalued by 14-team VBD standards.
Misconception: Projected points from different platforms are interchangeable. FantasyPros consensus projections aggregate from 20+ individual forecasters, which smooths extreme views but can also dilute sharp signals. PFF's individual model weights snap share differently than ESPN's staff projections. Treating all sources as equivalent inputs discards meaningful variation.
Checklist or steps
Steps for building a position-adjusted valuation before a draft:
- Identify divergences: players where VBD rank is 12 or more spots higher than ADP rank are candidates for early targeting; those where VBD rank is 12 or more spots lower than ADP are candidates for avoidance or fade.
