If you want to know how much run production a guy will help generate, and for some stupid reason you could only know one of his OBP, his SLG, or his OPS, and nothing else about him, then you should ask for his OPS.
But thatâs a ludicrous scenario and not something anyone should care about.
I donât think a statistic should be used if itâs not a good evaluation or comparison tool. OPS just became popularized by sabermetric people who probably got tired of just mentioning OBP and SLG independently.
As far as I know, most teams donât really use result based stats much at all when evaluating players. They use stuff like statcast data. Swing speed, exit velocity, zone rate, etc. for hitters. Spin rate, velocity, vertical approach angle, etc. for pitchers. For projecting forward especially.
I think thatâs overstating it. They use statcast data like that quite a bit, especially when coaching/developing guys, but I donât think itâs accurate to say that performance isnât considered much when deciding which guys to acquire, divest, or where to slot in the lineup.
Itâs hard to find a guy with an .800 OPS with OBP/SLG splits that disqualify him from being considered âuseful.â But your point very much stands; for anyone who wants to perform any analysis deeper than ranking a list of guys by OBP, it loses its value.
Itâs more than coincidental that the best offensive players have the highest OPS. Itâs a useful to stat determine who has the best combined OBP and SLG. I wouldnât use OPS to decide a line up but I would use OBP and SLG to help with that process.
This has long been my issue with OPS. It gives you less information than looking at OBP and SLG and you canât even get OPS without first knowing OBP and SLG. So whatâs the value in adding them together to give a cloudier picture of the player?
About the only time I think OPS serves any real value on its own is as a quick snapshot if the OPS gap is substantial (at least 100 points or more between two or more hitters). That would tell me that one hitter is much more impactful than the others.
