My friend (who I previously believed to be a knowledgeable baseball fan) were having a discussion about Greg Maddux (I claimed that he was the best pitcher of the past 30 years, but that is neither here nor there). To supplement my argument I cited his 120+ fWAR as something that made him great. He then responded with, "Don't give me that sabermetrics bullsh-t, Joe." "What's wrong with sabermetrics?" I replied. "It's stupid," he quipped, "It's things like: his batting average on day games played on the road on Tuesdays." I just sat there stunned at how stupid that was. Me not being very well versed in sabermetrics myself (I have a basic understanding of the simple ones, like xFIP, WAR, and UZR, but have no idea what constitutes a good ISO, for example), but I digress. I was wondering if you guys (and girls?) could help me help my friend see the light and embrace sabermetrics as I am slowly coming to. Thanks.
