Welcome to Nickknowsball

Nickknowsball is built around three ideas:

  1. You spend more time analyzing trades than you should. The Trade Finder
  2. surfaces every mutual-benefit deal in your league in one click. Both sides improve their starting-lineup expected points (SLEP) — no lopsided lowballs.

  1. You don't actually know who's good in your league. Every manager gets
  2. a recency-weighted grade across draft, trade, waiver, and luck-adjusted record. The "Trade?" badge tells you who actually responds to offers.

  1. Off-the-shelf rankings ignore your scoring. Switch to half-PPR or
  2. superflex and most sites' rankings break. Ours recompute on every league setting change.

The trade calculator works without an account

Drag any two players to either side of /calculator. The pool comes from our default-scoring rankings. League-size slider penalizes 3-for-1 stacking. Use it, share the link, no signup.

When to connect your league

The connect flow needs your ESPN league ID and (for private leagues) your SWID + espn_s2 cookies. Once connected, every tab becomes league-aware: trade suggestions use your roster, the calculator pool comes from your league's players, manager grades pull from your league's history.
