Three moves. Whole toolkit.
Everything on Offseason runs through three moves: connect your Yahoo league, come armed to draft season, then argue with receipts. Here's each one in detail, from the first sync to the artifact you drop in the group chat.
Connect your Yahoo league
Create an account with an email, then link your fantasy football league (Yahoo today, ESPN on the way). The connection is read-only: Offseason reads your league and never writes anything back. In a couple of minutes the whole history walks in with it, standings, champions, drafts, rivalries, keeper math, manager profiles. Your leaguemates join from a single invite link, with or without their own Yahoo account, and claim their team.
Come armed to draft season
Mock draft against personas built from what your leaguemates actually did in past drafts, with your keepers pre-applied and traded picks honored. Check every keeper against its round cost before the deadline. Price any trade in your league's exact scoring, and find out whether the other manager is likely to say yes before you send it.
Argue with receipts
The record book settles the old arguments: champions, last places, all-time head-to-heads, draft report cards. The Almanac writes up each season, the Gazette recaps each week, and every mock, trade verdict, and record posts into league chat as a card. Timestamped proof, printed for the chat.
What a synced league unlocks
Sync once and every tool lights up for everybody in the league. Each one scores in your league's own settings, not a generic average. Yahoo today, ESPN on the way.
Mock Draft
Draft against personas learned from your leaguemates' real drafts, keepers pre-applied, graded recap at the end.
Trade Machine
Two data planes, seven layers, 5,000 paired season sims, and an honest read on whether they'll say yes.
Record Book
Every champion, last place, rivalry, and draft grade your league has ever produced, in one place.
Keeper Advisor
See which keepers beat their round cost before the deadline, priced against your league's own board.
What-If Machine
Replay the season that wasn't. Undo a trade or reset a lineup and watch the standings move.
The Almanac
Every season written up: luck, regret, all-play records, and the weeks that decided it.
The Gazette
A weekly recap and preview for your league, written from real results and posted to the chat.
The Wire
Waiver receipts. Every add, drop, and FAAB bid your league has made, graded after the fact.
The Charter
Your league constitution, with an amendment history so nobody can rewrite a rule quietly.
How receipts work
Every tool ends in an artifact you can post: a graded mock, a trade verdict, a record that just fell. What happened, who did it, and exactly when. Timestamped proof, printed for the chat.
Receipts land in the group chat and stack in your league's record book. Over time they become the league's memory, the reaches, the steals, the trade somebody still defends. Nobody ever pays out. The receipt is the payout.
Draft season is coming.
Come armed.
Connect your Yahoo league in a couple of minutes, share one invite link, and the whole toolkit lights up for everybody in it.
