Transparent by design
The short version: start with the market, correct for asset consolidation, then add league and team context when it is available. Here is what each layer does.
Public player pages, rankings, and the free calculator begin with the most recent populated KeepTradeCut rankings cache available to the product. Superflex and 1QB values remain separate because quarterback scarcity changes materially by format. Market values reflect consensus sentiment; they are not performance projections.
Raw addition tends to overrate large packages. The calculator applies a nonlinear adjustment based on each player's value relative to the most valuable asset in the trade. That gives more practical weight to scarce elite starters and helps estimate the value a weaker side would need to add.
The public roster analyzer reads selected Sleeper league transaction history and compares the assets involved on a consistent dynasty-value basis. Filters let the user choose league format and treatment of draft picks. A grade summarizes the evaluated history; it does not know the private reasoning behind each deal.
After a user connects Sleeper, Dynasty Dealmaker can incorporate exact rosters, starters, league settings, draft capital, team strength, and potential trade partners. AI is used to synthesize those inputs and explain options. It does not replace the underlying data or guarantee an outcome.
Rankings and player pages refresh from cached source data on a regular schedule. Values can move quickly after injuries, news, roles, and NFL transactions. Third-party data can be delayed or incomplete. Every result should be treated as decision support, then checked against current league conditions.
Use rankings and the calculator to establish market price. Use the report card to inspect past behavior. Both work without an account.
