Every tool, reading your Yahoo league
The general pages below describe each tool; connect a Yahoo league and every one of them runs on it.
What the Yahoo fantasy football tools cover
- A league analyzer for every Yahoo league on your account: power rankings, playoff odds, team grades, trade grades and a report card
- A trade analyzer and a trade finder that read every Yahoo roster
- A lineup optimizer and start/sit board scored under your Yahoo league's own settings, bonuses and defense scoring included
- A waiver wire ranked by the lift to your lineup, beside each team's waiver priority or FAAB budget from Yahoo
- Your completed Yahoo draft board, every pick named
- Yahoo leagues are read-only here: the tools show the lineup to set, the claim to make and the trade to send, and the move itself is made on Yahoo.
How the Yahoo connection works
Yahoo connects with OAuth, the same sign-in other Yahoo apps use. You sign in to a free StatChasers account, press Connect, and approve read-only Fantasy Sports access on Yahoo's own page. Yahoo then shares the leagues on that account, public or private, and the connection follows your StatChasers account to every device. We never see your Yahoo password, and you can remove access from Yahoo's security page at any time.
What is different on Yahoo
Yahoo leagues are scored with Yahoo's own stat categories, so every analyzer translates your league's exact scoring first (yardage and touchdown points, threshold bonuses and team defense brackets) and runs in those rules. Lineups are the real ones you set on Yahoo, bench and IR included.
What is written back to Yahoo
Yahoo leagues are read-only here: the access you approve is read-only, so the tools show the lineup to set, the claim to make and the trade to send, and the move itself is made on Yahoo.
Yahoo Fantasy Football Tools FAQ
Which fantasy football tools work with Yahoo?
The full analysis suite reads Yahoo leagues: league analyzer, trade analyzer and finder, lineup optimizer, start/sit, waiver wire, playoff odds, rankings, projections and your completed draft board.
Are the Yahoo fantasy football tools free?
Yes. The StatChasers account is free, connecting Yahoo is free, and so is every analysis on your leagues.
Do I need to give you my Yahoo password?
No. You sign in on Yahoo's own page and approve read-only access; Yahoo shares your leagues with us without ever showing us your password.
Why do I need a StatChasers account for Yahoo?
Yahoo's access is granted to an account, not to a browser, so it is stored against your StatChasers account. That is also why your Yahoo leagues appear on every device you sign in on.
Does it work for private Yahoo leagues?
Yes. Yahoo shares every league on your account, public or private, because you approved the access yourself.
Can the tools make moves in my Yahoo league?
Yahoo leagues are read-only here: the tools show the lineup to set, the claim to make and the trade to send, and the move itself is made on Yahoo.
Do these tools work for dynasty leagues on Yahoo?
Season-long only here. For a Yahoo dynasty or keeper league, Dynasty Command is the right half of StatChasers, linked below.
