Today is a very good day for this article. Why? Well, that is because this past week on Twitter Dave and I have gotten into multiple arguments with people on Twitter about rather OPS is a good stat to evaluate hitters on or not.
In case you were wondering, OPS is not a good stat to evaluate hitters on. OPS is influenced too much by slugging percentage to be a reliable stat. On average, one point of on-base percentage is 1.8 times more valuable than one point of slugging percentage. Yet, slugging percentage carries more weight than on-base percentage does in OPS.
