How Do Win Shares Work?
Offensive Win Shares
OWS = marginal offense / 10.65. Marginal offense = points produced − (possessions used × league pts/poss × 0.92).
Defensive Win Shares
DWS = marginal defense / 10.65. Marginal defense uses steals, blocks, defensive rebounds, minus turnover penalty.
WS/48
WS/48 = (WS / Minutes) × 48. League average ~0.1. Elite players exceed 0.2.
