Leaguenomics
Analytics aimed at how the managers in your league actually play, borrowing from finance: overtrading, selling winners early, risk-adjusted scoring.
About
The premise is that a league is not a liquid market of rational players, so the tool measures behaviour instead of predicting what a given player will do — lineup efficiency, draft alpha over time, waiver wire efficiency.
The second bet is social. The creator's framing: the NFL plays on Sunday, your league plays all week, and the platform is built for the group chat around it.
