A program which measures team chemisty and analyzes a player's impact on his team's ability to produce points. WINVAL is the labor of Jeff Sagarin and Wayne Winston, who are both graduates of MIT.

WINVAL's most unique characteristic is that it measures individual and team performance after every lineup change in every game. WINVAL's ratings also factor in who each individual is playing with and against at all times. The WINVAL scouting reports also include data on referees.
