Win Shares seems to be the Bill James attempt to create the super stat to end all stats, but it really hasn't seem to have caught on. The Hard Ball Times has the most recent data on it and in a very nice format, but it must be too early to put 2006 win shares out there: Hard Ball Times They also link to some good explanations on what all goes into the stat. It's really too complex for mere mortals like me, but I like the concept: "Bill James invented Win Shares as a simple way to compare baseball players. The idea was to develop a statistic that allows you to compare shortstops and outfielders, starters and relievers, relievers and shortstops, etc. Since the win is the ultimate measure of success, James developed a stat that measures each player's contribution to his team's wins, or Win Shares." So why haven't Win Shares caught on? Could it still? Will it ever replace the old school (averages/totals) or even some of the new school (OPS/OBP)?
