How the Taco Risk score works
A league doesn't die in one dramatic moment — it dies quietly, one checked-out manager at a time. The detector reads your league's public Sleeper activity and grades the seven things that actually kill leagues: a tyrant who wins every year until nobody else bothers, the most lopsided trade, a waiver-wire hog, ghost-town teams that stopped making moves, a dead market with no trades, blowout-heavy weeks, and — the one thing working in your favor — how many seasons the league has survived.
It's meant to be funny, not scientific. But the signals are real: a league full of tacos really is a league on the way out.
Want to not be next year's taco?
The detector tells you who's checked out. The SharperSunday app keeps you from being them — an AI co-manager that reads your roster, your league, and the waiver wire and tells you exactly what to do each week. Start free and let the AI carry your lineup so nobody screenshots you next season.
Frequently asked questions
What's a “taco league”?
A “taco” is fantasy slang for a checked-out owner who never sets a lineup, makes no moves, and barely knows the rules — the term comes from the clueless Taco character on FX's The League. A “taco league” is one riddled with them, which is exactly the kind of league that quietly dies. This tool measures how taco-fied your league is.
How is the Taco Risk score calculated?
We read your league's public Sleeper data and score seven “death factors”: a historical tyrant who wins every year, the most lopsided trade, a waiver-wire hog, abandoned “ghost town” teams, a dead transaction market, blowout-heavy weeks, and — working in your favor — how many seasons the league has survived. They blend into one Taco Risk percentage.
Who's the “biggest Taco”?
It's the most checked-out manager we can find — the one leaving empty starting slots and making no moves all year. It's all in good fun and grounded in real Sleeper activity. Screenshot it, drop it in the group chat, and let them defend themselves.
Do I need an account?
No. Type any Sleeper username (or paste a league ID) and you'll get a verdict in seconds — no login, nothing to install. If you want the AI to actually fix your roster so you're not next year's Taco, that's what the app is for.
