## Overview

sports-draft is a Streamlit sports draft-room app: users select leagues and participants, draft teams in a snake-style room, then review standings and pick analytics. The sampled source shows probability refresh, draft-pool setup, pick normalization/commitment, and analytics calls, all within draft.py. The README provides no capability detail, and source excerpts omit parts of the app, so uncertain wiring and persistence are not represented.

Main entry points: [`draft.py`](https://github.com/krishanu-datta/sports-draft/blob/main/draft.py) (Streamlit app)
