Fantasy Premier League
Fifteen players, one free transfer, a hard deadline.
Fantasy Premier League is a weekly exercise in decision-making under uncertainty with a hard deadline — pick fifteen players on a budget, one free transfer, prices moving overnight. I treat it as a small data problem, which is either the right way to play it or an elaborate excuse for the spreadsheet.
It's also how the world-cup-fantasy tracker in my projects happened: my four-manager league kept arguing about who was actually winning over the course of a tournament, so I built the thing that keeps receipts.
