WHAT IT DOES - Next Pick — your top recommendations at this exact pick, with projected points, value vs. ADP, and stack pairing suggestions - Value Board — every available player ranked by your own tiers, with real-time vs-ADP deltas updating as the board moves - Build Health — live roster grade tracking position balance, stack correlation, bye coverage, and what you need next - Tier Alerts — fires the moment a tier is about to break so you never miss the last receiver at a quality level - Exposure Tracking — import your Underdog exposure CSV and see your ownership % on every player, right on the board YOUR RANKINGS, NOT OURS Draft Logic doesn't have house rankings. It reads whatever CSV you upload or our default rankings. The recommendations come from your own tiers and rankings, not an algorithm you can't see. DESIGNED FOR UNDERDOG BEST BALL Built specifically around Underdog's best-of-5 format, half-PPR scoring, and the stack theory that actually wins Best Ball Mania — QB-WR correlation, bring-back logic, and positional scarcity by tier. PRIVACY Draft Logic reads visible player data from the Underdog draft page. It does not automate any actions, intercept any network requests, or access any data beyond what's visible on screen. Your rankings file stays on your device.
