NBA Trade Analyzer
Prices any trade in free-market dollars: player surplus (projected production value
− salary, with aging, durability and a new-team adjustment), draft picks as E[surplus] over landing
distributions (protections priced as options), and championship equity from wins + star
concentration. Players are rated by Marginal Plus Minus (mPM), points per 100 possessions against an
average player; production is Marginal WAR (mWAR). Tax money is a footnote, not wins.
