Rook
Builds its own player valuations from raw data instead of averaging everyone else's projections, hunting for what the market undervalues.
About
A year's work after a smaller draft assistant did not pan out. Rook reasons over a range of variables to land on a number, and flags dependencies between players — who gets capped when someone else arrives.
Live draft help comes through a Chrome extension that reads your draft room, covering Yahoo, ESPN and Sleeper in both auction and snake formats. In-season tools include a trade tool that proposes reasonable trades.
