Win Shares

This table shows the offensive, pitching, and defensive Win Shares for each team. It then breaks down the defensive Win Shares into each position. Win Shares are a Bill James creation described in his excellent book, Win Shares. To quote James (p. 2),

    "Win Shares are, in essence, Wins Created. . . or actually, thirds of a Win Created. Win Shares takes the concept of Runs Created and moves it one step further, from runs to wins. This makes it different in essentially two ways. First, it removes illusions of context, putting a hitter from Yankee Stadium on equal footing with a hitter from Colorado, and putting a hitter from 1968 on equal footing with a hitter from 2000. Second, the Win Shares system attempts to state the contributions of pitchers and of fielders in the same form as those of hitters."

A detailed explanation of Win Shares is beyond the scope of this document. For more information, I encourage you to check out Win Shares by Bill James.
