About

Shoulda Started reviews your Sleeper fantasy football lineup against the best one you could have set, and calls every mistake like a penalty, with the points it cost you.

What you get

• A weekly penalty report for every team in your league, shareable as an image.
• League awards each week: high score, biggest blowout, robbery, unluckiest.
• A season report with true standings, luck, and a schedule swap.

How it works

Your browser reads your league from Sleeper's public data, and all the maths runs on your own device. There are no accounts and nothing is stored on a server. You can read exactly how each number is worked out in the guides.

Why it is free

It is free to use. If ads are ever added, they will be limited and will never appear inside the image you share.

Not affiliated

Shoulda Started is an independent project. It is not affiliated with, endorsed by, or sponsored by Sleeper or the NFL. Team and player names come from Sleeper's public data.
