I know I'm going to make myself look like and idiot for asking this, but how is the win-share number determined, and how useful is it in evaluating a player?

A lot of people don't know what this means or what it is for, but here is an explanation.

A Win Share determines how much you are responsible for your team winning. It basically says who is the most important player on the team giving the production for your team to win.

James made team Win Shares directly proportional to team wins. In his system, a baseball team that wins 80 games will have exactly 240 Win Shares, a baseball team that wins 90 games will have exactly 270 Win Shares, etc. In my system, a basketball team that wins 50 games will have about 50 Win Shares, give or take.

James did not allow for the possibility of negative Win Shares. In his system, the fewest number of Win Shares a player can have is zero. In my system, a player can have negative Win Shares. I justify this by thinking about it in the following way: a player with negative Win Shares was so poor that he essentially took away wins that his teammates had generated.



So if a team wins 60 games, it spreads across the team to determine how much each player is reponsible for the team winning and thus each player gets a win share.

Take for example the Lakers.

Rk Player WS
1 Pau Gasol 14.7
2 Kobe Bryant 10.3
3 Lamar Odom 10.1
4 Andrew Bynum 6.6
5 Ron Artest 4.4
6 Derek Fisher 3.7
7 Shannon Brown 3.1
8 Matt Barnes 3
9 Steve Blake 1.8
10 Devin Ebanks 0.4
11 Derrick Caracte 0.3
12 Trey Johnson 0.1
13 Theo Ratliff 0
14 Joe Smith -0.1
15 Sasha Vujacic -0.1
16 Luke Walton -0.2
Total Win Shares = 58.1


Expected W-L: 58-24 (3rd of 30)
Actual Record 57-25, 1st in NBA Pacific Division

So your win shares of the entire team usually equals the Expected W-L record.
