Why choose OPS instead of OBP? OBP is a great stat, and it's an important skill for a hitter, but it misses out on extra base hits. For the kind of illustration that sveumrules needed to provide, extra base hits should be included. While OPS doesn't give enough weight to OBP, it often comes close enough to being reasonably accurate. Plus, it offers convenience and familiarity. The question that came up involved good months vs. bad months. For monthly splits, you're best off with a rate stat. OPS is an appropriate way to illustrate that. It's to the point, and it's not as cumbersome to read as a string of slash stat splits. If you're comparing two players with similar OPSes, you might be forced to use slash stats, or you could use one of the more advanced rate stats. There are definitely times when people cherry pick around here, and there are times when they don't necessarily choose the best stat to illustrate a point, but this isn't one of those cases.
