What it is

A Python script scrapes ESPN rankings and depth charts and builds one self-contained HTML file to open on draft day.

Highlights

  • Type-ahead pick entry, with tier dividers and chips showing how many players are left at each position and depth-chart role.
  • Depth-chart panels, so you can see a team’s backfield before taking a running back.
  • Undo and state that survives a page refresh, saved in localStorage.

Methods

Python, Web scraping, HTML, Vanilla JS, localStorage.
