Mark Cuban does WOWY/UZR/WPA in basketball

By Tangotiger, 11:37 AM

Here it is:

We have developed and enhanced a player and lineup evaluation system. We have been working on this for the last 8 years. Its far from perfect, and its greatest value is that over a period of years we have been able to identify trends to help us identify up and coming, starring and declining players. It also helps us understand what combinations of players work well together, and which dont.

To give you a basic understanding of the system, at its most basic its a plus minus system. Then we adjust it to take into account who the opponent is, is it home or away, are you playing against the other teams good lineup or bad lineup, what the score and game clock are (scoring the game winner is worth more than the 1st basket of the game. Scoring when up by 30 is worth nothing). If the team scores or gets a stop when the game is on the line, then your impact percentage goes up. We reward for getting the job done when it matters.
