Fantasy baseball dashboard that treats source disagreement as the primary signal.

Strengths
  • Visualizing source divergence instead of consensus reveals actionable market inefficiencies.
  • League-specific calibration (Z-scores, VORP) beats generic rankings for actual drafts.
  • xStats section identifies buy-low candidates based on hard contact vs. outcomes.
Weaknesses
  • Dependency on ESPN/Yahoo API stability could break core league synchronization features.
  • Niche appeal limits broader developer interest beyond fantasy sports enthusiasts.

Post Description

Most fantasy tools hand you a list. One source, one opinion, presented as settled fact. This one shows you the argument behind the list: where your sources agree, where they diverge, and what the divergence means. Source disagreement is the feature. A player ranked 40th by consensus but going in the 70s in ADP is a market inefficiency. A player ranked 40th by consensus but 90th by Statcast projections is a question worth asking. The tool surfaces those gaps rather than collapsing them into a clean number.

Rankings and xStats work without a league connection. The xStats section identifies hitters whose surface stats diverge from their expected stats, players whose hard contact has been finding gloves at an unsustainable rate, and gives you the buy signal before the correction happens.

Connect your league and it builds around your actual scoring context. Z-scores calibrated to your draftable pool. VORP measured against real positional replacement levels scaled to your league size. Tier clusters sized to where the projection uncertainty actually lives.

No subscription. No premium tier. No account. The analysis is accountable only to whether it's right.

Demo mode is available if you want to explore before connecting. Midseason mode generates a full simulated season so every feature has real data behind it.

The FAQ is at leaguedonation.com/faq.html. The colophon covers the methodology in detail if that's your thing.

Zenhub Analytics for Multiple Workspaces

This nails a small but painful gap: multi-workspace ZenHub analytics with live velocity and burndown charts plus per-team performance breakdowns. The landing is clean and confident, but there aren’t enough signals about data sync reliability, security, or export/reporting features — adoption will depend on those operational details more than the UI.
