About The Box Score
Fantasy football tools that use your league's actual settings.
Who runs it
Nick, who has played fantasy football on ESPN, Sleeper and Yahoo for more than a decade. Most trade calculators ignore superflex, TE premium, dynasty contracts and playoff schedules. This started as his spreadsheet to fix that.
Each tool came from a real problem in one of his leagues. The trade finder came from failed midseason swaps. Manager grades came from an argument over who drafted well.
What it does
Rankings, trade suggestions and manager grades use your league's scoring, roster slots and history. The trade finder ranks deals where both rosters improve. Manager grades weight recent draft, trade and waiver calls more heavily.
Data
Projections blend ESPN's in-season numbers, consensus rankings and nflverse weekly usage data. Manager grades use every season your league exposes through the ESPN or Sleeper API. The trade engine starts from each team's starting-lineup expected points (SLEP).
