Crowd9 is a community-driven dynasty baseball valuation tool. Instead of one analyst handing down rankings, we ask the crowd a simple question over and over — “who’d you rather have?” — and turn thousands of those head-to-head picks into living player values.
Every pick in the Player Picker feeds an Elo rating system, the same approach used to rank chess players. When you choose one player over another, the winner gains rating and the loser drops. Beating a consensus favorite moves the needle more than beating a deep sleeper, so the board sharpens toward what the community actually believes.
Those ratings map to the 0–10,000 values you see across the Rankings and the Trade Calculator. Top Risers and Top Fallers track how a player’s value has shifted over the last 30 days.
Dynasty and keeper-league managers who want a fast gut-check on player value and trade fairness — grounded in the wisdom of the crowd rather than any single ranker’s bias.
