OPS is nothing but BS

Postby joshheines » Fri Aug 11, 2006 9:18 am

So, I'm sitting here thinking, man, OPS is a BS statistic that has become popular because it's A) simple and B) get's you to magical numbers like 1.00. However, the stat is wholly fallacious, faulty and inaccurate. It's a statistic that attempts to represent a player's overall batting ability; however, OPS rewards those players with gaudy batting averages and hurts those players with pedestrian or below average batting averages. OPS represents a player AVG twice. It gets factored once in OBP and then again in SLG.

In my mind, it's more accurate to take the base OBP and add in (SLG-AVG[isolated power]). This is the true mark of OPS. The present OPS stat inflates guys like Pujols, Manny, Berkman and Dye and deflates guys like Giambi, Dunn and Glaus. For purposes of real baseball don't we want to know how many total bases and player has created? Then why do we count all hits twice? Doesn't make sense.

Under the present OPS system Giambi is ranked 9th, Dunn is 19th and Glaus is 27th. Under my proposed (to no one except the cafe) OPS, Giambi ranks 3rd, Dunn is 11th and Glaus is 13th.

Conversely, those benefitting from the present OPS are Miguel Cabrera(11th), Joe Mauer(14th), Chase Utley(18th) and Nomar(23rd). Under my system Cabrera ranks 18th, Mauer's 34th, Utley is 31st, and Nomar ranks 35th. Mauer's drop is indicative of what is wrong with the present system.

Any thoughts?

OPS is quick and dirty, its easy and its fun. :-B I like it. ;-D

Average is counted twice, but as such it mostly cancels itself out. If Giambi moves up to #3 and Dunn #11, that right there is an indication that all is not right with your system.

And there is a whole additional calculation to be done! My mind is tired already. :*)

Can you present a list of top30 side by side using ops and using isolated power? That would be good for comparison.

I think the theory behind your proposition sounds pretty good. We might need to see a top 25 ranking of current OPS and Proposed New OPS in order to get a better feel for it.

I like it too. Your new list looks like a who's who of baseball studs.

I've been thinking the same thing: OPS factors avg twice

OPS is like any other stat usefull but not perfect. IMO OBP is much more important than SLG or isolated power so I don't think they should be given equal value.

It's a fact. OBP contributes more to run production than slugging. That's always been the problem with OPS.

That why joshheines formula might be better because it increases the contribution of OBP.

Some saber guys can probably respond to this better than me, but there are two main components to producing runs: the on-base factor and the advancement factor. When you hit a single, not only do you get yourself on base, but you move any runners over as well. That's why you "count all hits twice". There isn't any advancement factor to speak of when you take a walk. OPS isn't perfect, but it's somewhat decent because it takes both the on-base and advancement factors into account. I think your stat is flawed because it appears to value a walk is just as much as a single, which isn't the case.

OPS is a joke. I've never understood how it gained such popularity. I hope the big sabremetrics guys do not endorse it in any fashion. You're adding two numbers with completely different denominators, for God's sake! It's got no conceptual meaning. You can't tell a thing about a player by looking at his isolated OPS other than, perhaps, that he's pretty good, or he sucks. If you've got a great OPS, what are you good at? Getting on base? Piling up the bases? Beats me. And everyone else. You don't know. You're good at something, but we don't know what. It's not true at all that it's like any other stat. It's like NO other stat that I've seen. It tells no story. It's a sham.
