Who should I start in fantasy football this week?
Start the player with the better projection for your scoring once practice reports and weather are in. Lean on ceiling in a must-win week and floor when you're favoured. This tool compares sportsbook-implied projections, rankings, practice status and kickoff wind for two or three players.
Fill in the prompt
Edit the details in brackets with the two or three players you're choosing between and your league's scoring, then pick the AI assistant to run it in.
Firecrawl Alexandria runs the lookups
Your assistant calls 5 tools in order, from StartWho NFL fantasy projections, Draft Sharks NFL rankings, FantasyData NFL rankings, NFL.com and National Weather Service API (api.weather.gov), and cites the record behind every figure.
Get the answer
You get a side-by-side of projections, floor and ceiling, practice status and kickoff wind, the start call, and the news that would flip it. Anything a source couldn't find is marked, not guessed.

Frequently asked questions
- How does the tool decide who to start?
- It compares each player's sportsbook-implied projection, the floor and ceiling from weekly rankings, an independent site's rank, Wednesday to Friday practice participation and the wind forecast at outdoor stadiums. It favours ceiling in a must-win week and floor when you're favoured.
- When should I run it?
- Late in the week, after Friday's injury report. Run it again before kickoff if a player is questionable, since the call names the news that would change it.
- Is this tool free?
- Yes. The prompt, the steps and the instructions are free to use. When your assistant runs the tool through Firecrawl Alexandria, each data call bills its listed price in credits, and every data source shows that price before it's called.
- Which AI assistants can run it?
- Any assistant connected to Firecrawl with an API key, including ChatGPT, Claude, Claude Code, Codex and Cursor. Pick one in the prompt box and your request opens there with a link to this tool.
- Do I need to sign up?
- You need a Firecrawl account, with your assistant connected through its API key. Firecrawl Alexandria doesn't run in keyless mode. If your assistant isn't connected yet, the prompt tells it how to set that up. Some data providers ask an admin on your Firecrawl team to accept their terms before the first call.
