I think Bill James has thought deeply about how to do this for a long time, dating back to the "Defensive Winning Percentage" methodology from his early Abstracts -- in fact, he's recently published some similar stuff on his website.<br /><br />However, I think that the weaknesses of the Win Shares system are such that even if you decided that James' approach to fielding was something you wanted to incorporate, you would be better off converting it to a runs above average metric that could then be integrated into a WAR implementation, rather than using the entire Win Shares sytem.<br /><br />My apologies for neglecting to post your comment in a timely manner -- appreciate you reading!phttps://www.blogger.com/profile/18057215403741682609noreply@blogger.comtag:blogger.com,1999:blog-12133335.post-22721496046038099002020-01-10T11:01:07.145-05:002020-01-10T11:01:07.145-05:00I'm a baseball fan in South Korea.

In Korea, WAR is considerated inaccurate and useless because of inaccuracy of fielding stats, replacement level, etc. In Korea, fielding stat exists which is called FSR (like TZ), but people don't trust that much due to doubts about its accuracy. So could Win Shares be an alternative to WAR? I know it is actually dead, but stats in Korea are unreliable. I want to know your opinion.
