There are some well-reasoned, cogent explanations of WAR's value and shortcomings in this thread. In particular, I believe jay, kab21 and drjim have all provided some insight for those who might be interested in learning more about WAR and advanced statistics. Some important kernels that bear repeating: -No metric is perfect- each statistic carries its own blind spots. Some statistics have more blind spots than others. -All statistics are susceptible to misuse when small sample size or confirmation bias exist. Look at this thread for an example: http://twinsdaily.com/topic/10150-fun-with-numbers-2014/ -Some statistics are better for describing what happened in the past, while others have more predictive value. -------- The present clamoring against WAR's defensive component is not at all unfounded. For those of you who are frustrated with the difficulty of comparing player defense and WAR, consider another statistic I believe is much simpler-- wRC+ wRC+ is a metric used to measure offensive production. wRC+ considers individual events (how much value a single has compared to a double or home run) and weights them accordingly. Finally, wRC+ measures a player's offensive output against LEAGUE average, not replacement level, and presents it as x% better or worse than league average. A player with a wRC+ of 140 is currently producing runs at a rate 40% better than league average. It is a rate stat rather than a counting stat, so be wary of SSS. wRC+ accounts for park factors and is a reliable way to compare players' offense from different eras. wRC+ is absolutely my go-to when I need to figure out how good a player's offense really is. Of course, a SS with a wRC+ of 120 is probably more valuable than a first baseman with a wRC+ of 120. In conjunction with other stats, wRC+ is a great way to measure player value. I think it's a good starting point for anyone interested in sabermetrics. See link for a thorough yet accessible explanation of wRC+: http://www.fangraphs.com/library/offense/wrc/
