Overview
This document presents a comprehensive view of an ADP tracker tool used for fantasy football research. It compares several major drafting platforms—ESPN, Sleeper, Yahoo, and Underdog—across a large roster of players, capturing values such as per-player ADP, platform deltas, and round differentials. The dataset is intended as a decision-support tool for pre-draft analysis, highlighting where values may shift depending on the platform and where there are notable discrepancies between sources.
Key context and notes from the source material include:
- Yahoo ADP data may cut off early in some exports, which can influence perceived player value if interpreted without guardrails.
- Sleeper ADP data sometimes lags behind other sources; this lag is a known limitation of the data pipeline used to populate the ADP file.
- The content credits FantasyLife for their extensive ADP data and mentions the importance of using this tracker as one of several research tools rather than a definitive source.
- Underdog is described as a 3-WR platform, which can cause WRs to be drafted earlier relative to a 2-WR environment; this bias should be considered when interpreting value and round-differential signals.
- The narrative emphasizes that the tool is designed to aid, not replace, broader draft strategy and research.
【Note: The source includes long-form, multi-table data and explanatory notes that accompany the ADP comparisons. This section captures the core purpose and contextual warnings provided in the document.】

...Note: This is a representative excerpt from the original dataset. The full dataset contains many more rows and columns across players, teams, and multiple platform comparisons. The values shown above illustrate the format and types of data included (ADP values per platform, platform differences, and round differentials).
How to Read the Data
- Columns explain per-player ADP across four platforms: ESPN, Sleeper, Yahoo, and Underdog.
- The “Difference” columns show how a given platform's ADP compares to Underdog or another reference point, typically expressed as ESPN - Underdog, Sleeper - Underdog, Yahoo - Underdog, or ESPN - Sleeper, depending on the row and data block.
- “Round Differential” indicates the change in value when converting ADP into rounds (e.g., 12.04 means 12th round or a 12th-round projection depending on the scoring context). The numeric values reflect the magnitude and direction of the difference.
- The section labeled Values on ESPN and similar notes show how ESPN’s base ADP would translate into the other platform’s directionality when comparing to that reference.
- This dataset emphasizes that platform biases may affect perceived value, especially with Underdog’s 3-WR platform dynamics and Sleeper’s data lag tendencies.
Important interpretation guidelines:
- Positive numbers indicate a platform or metric is ahead (ahead of Underdog or Sleeper as the reference), while negative numbers indicate the opposite.
- The presence of large differences often signals potential draft value opportunities or caution flags depending on your drafting strategy and roster composition.
- Use this tracker as a supplementary tool to inform, not decide, your overall draft plan.
Notes & Observations
- Underdog is a 3-WR platform, which can inflate WR ADP relative to a two-wide-receiver setting; consider this when evaluating WR values across platforms.
- Sleeper ADP data can lag behind other sources; cross-check with live app data when possible.
- Yahoo ADP exports may truncate early on some datasets, which can skew early-round comparisons; treat such data as indicative rather than definitive.
- This tracker credits FantasyLife for extensive ADP data; it’s designed to be one of several tools used in pre-draft research.
- The table also includes per-player “Round Differential” values, offering a quick sense of how many rounds apart players may be across platforms.
- The notes emphasize using the tracker for context rather than as a sole decision-maker and remind readers of platform-specific drafting biases.
Appendix: Representative Rows

Conclusion
This ADP tracker provides a multi-source look at player values across ESPN, Sleeper, Yahoo, and Underdog, highlighting where platform biases create differences in ADP and round differentials. Use the data to inform draft strategy, but always corroborate with live data from your preferred platforms and tailor your approach to your specific league rules and roster needs. The document notes caution about data lag, platform biases, and the need to view this as one of several tools in your pre-draft research workflow.

Thank you for using this ADP Tracker Tool. If you would like to get updated when I make changes to this sheet or if you have any questions, follow my Twitter @Beardahn54. A few notes about the spreadsheet: Yahoo ADP cuts off early, so remember that before drawing broad conclusions about player value. The data is a tool for research and should be used alongside other sources. Sleeper ADP can lag behind other sources. The data source credits FantasyLife for extensive ADP data. Underdog is a 3WR platform, so WRs will often appear earlier than in a 2WR format. Enjoy!
