wRC+ and other "Park Adjusted" stats

[bpj]

Well. since wRC (weighted Runs Created) and we expect one WAR for 10 runs created, it would be silly to think it doesn't affect WAR.

It doesn't matter though, that those who wanted Trea Turner who has a lower OPS than JP, those people were wrong about Trea Turner, or CC improving the offense.

I would say anything relying on "park adjusted" numbers has an obvious problem currently.

And, absolutely, the way to improve the offense the last couple years was definitely in the 1B/DH market, not the highest paid position on the field.

I try to use multiyear stats when comparing players for acquisitions. Front offices probably use more advanced stats. I can imagine something similar to xwOBA with adjustments.

Absolutely, they could make wRC+ (and I assume most other park adjusted stats) much more accurate.

I think what they're doing isn't just comparing apples and oranges.

They're slicing up the apples and oranges and putting them in a ziplock bag together.

If everyone knows that parks affect right handed and left handed batters differently, and that using multiple years can be much more reliable and accurate, why wouldn't they do it that way?

It wouldn't be any harder for them to use LH park factors for LH batters and RH park factors for RH batters. And switch hitters would obviously be perfect for using the overall blended number.

They will probably say there isn't enough data by using just one or the other, but it's not doing anybody any good by using the blended number and skewing everybody's results, and that would be another good reason to use multiple years of data.

This is perhaps the biggest condemnation of wRC+ imaginable

Because you think it's being utilized for that?

Well be are listed 4th in the tweet and here are our offensive AL rankings:

wRC+ 4th
Runs 7th
BA 9th
OPS 9th

I don't know, it seems like a stretch. Maybe they do something similar to how the individual Silver Slugger Awards are given out. Have you seen something on individual Silver Sluggers being based on wRC+?

I remember reading somewhere that they used a rolling or multiyear park factors.
