Your roster skews old at the top. Here is the win-now asset to move and what a rebuild-friendly return looks like:
| Path | This year | 2-year outlook |
|---|---|---|
| Hold Whitfield | Stronger | Declining |
| Trade for 2 firsts | Weaker | Stronger |
Based on your roster needs (thin at RB, aging WR core), top rookie fits available at your pick:
Looking at your Fantrax contracts against expected production, here is the hold-versus-cut read:

Why League Loom
Multi-year roster brains for dynasty leagues
A dynasty decision needs both your current roster and the rules that shape future value. League Loom retrieves supported rosters, standings, draft results and available players.
Fantrax may also return salaries. Confirm future pick ownership, keeper costs and contract terms yourself when they are missing.
Ask the assistant to compare your lineup and depth before and after a move, separating league facts from player forecasts. Current tools retrieve or analyze data; you make all moves yourself.
FAQ
Questions
Is there an official dynasty AI plugin, and is League Loom safe to use?
League Loom is an independent MCP connector, not an official product of ESPN, Sleeper or Fantrax. All current tools retrieve or analyze data and cannot submit roster moves. Provider credentials are sealed in your encrypted connection, with an optional encrypted email recovery backup.
Can it see contract and keeper values for my dynasty league?
Fantrax may return player salaries, but complete contract terms, future costs and keeper rules are not guaranteed. Supply any missing details before comparing a trade or keeper. ESPN and Sleeper provide supported roster, standings, draft and player data; do not assume every dynasty-specific field is available.
Does it cost anything or require API keys?
No. League Loom is free and needs no API keys. You add the connector in your AI tool, pick your team, and start asking. There is nothing to install on your computer and no developer setup.
Which platforms and sports work for dynasty football?
For NFL dynasty, League Loom supports ESPN, Sleeper, and Fantrax. It connects over MCP, so it works with Claude, ChatGPT, and other MCP-capable AI tools. You can also connect multiple leagues and ask the AI to compare your dynasty rosters across all of them at once.
