Fantasy Football Tool

Helps suggest relevant players to you during your draft.

A browser extension tracks the players that have been picked so far. It sends this information to a Python script, which filters the remaining player options. This lets ChatGPT give its opinion on the current state of the draft.

Usage:

Pre-draft setup:

Get the data

I used two files:

1. ADR.csv = Abusing Draft Rankings, from JuiceBoxOne Reddit
2. ECR.csv = Expert Consensus Rankings, downloaded from FantasyPros

Run parse.py to generate combined_with_depth.csv

Get the analysis

Put your analysis files in the analysis directory Run not_found.py to generate a list of all the players not in the analysis directory, not_found.csv I got the analysis mostly from reddit comments.

Setup your ChatGPT API Token

You need to get an OpenAI API Token Put it in .env, e.g. OPENAI_API_KEY=your_api_key

Setup your browser

On Firefox, go to about:debugging, click "This Firefox", and "Load Temporary Add-on" Then select the extension/manifest.json file Make sure its running/reload it if necessary. Can check its log with "inspect"

During Draft

1. Run python3 main_http.py & This receives responses from the browser extension, and records the current picked players & pick number in log/pick.txt and log/player_$timestamp

2. Run python3 filter.py && python3 ask_gpt.py This prints ChatGPT's response to your console. filter.py removes picked & irrelevant players so the correct files can be fed to ChatGPT.

3. Update log/current_team.txt during your draft

Note you can change the model, I currently have it as GPT_MODEL = "gpt-4o"

Notes/TODO

I couldn't figure out how to get Depth.csv from FantastyPros, so I just rank the players WR1, etc. based on their ADP rankings.

I try to log all relevant the files with a timestamp in case something crashes.

I can see it being very hard to use this if you aren't familiar with python, I'm not sure how to make it easier. Compile an exe with a GUI?

The code is pretty simple/self contained, but definitely not the best organized thing.

I've only tested it in Firefox/ESPN. I put a sample chrome manifest.json but haven't tested it. Modifying it to use other platforms would involve changing the const playerElements = document.querySelectorAll('.jsx-2093861861.pick__message-information .playerinfo__playername'); query in content.js to whatever those platforms use to identify pick information.
