Rough Draft Football site
It's not fantasy focused (yet) but I built a webapp (Edit: it is largely vibecoded) that is basically an interactive NFL draft board showing all the picks dating back to 2000. You can filter on year, team, position or college and inspect each player, showing not just their career stats but the stats for each team they've played for and how they rank against other players of the same position and draft class.
The gimmick is that you can vote on whether a player is a bust or a success. It's a tongue and cheek measurement, as each player is different but it drives conversation
Anyway, the site is https://roughdraftfootball.com/ if anyone is interested in checking it out. As hinted above, I plan on adding a fantasy element (a fantasy draft board driven by ADP) but that's coming later.
