You start saying that ERA is not a good stat for relievers but in the very next paragraph you point out that his ERA+ was very good. You are a mass of contradictions lol
Do you know what ERA+ even is?
One reason I don't like ERA for any pitcher is that it does not factor in park factors as well as others (like team defense). ERA+ does just that. It is way more accurate than just plain ERA.
Another other reason I don't like ERA is that RP'ers often come in with 1-2 outs, so their ERA will be skewed in those games.
I provided ERA+ numbers to show his ERA was not as bad as it looked. It was your stat of choice, so I countered your point with a similar stat.
Before 2021 his standard and advanced stats weren't very good as you are suggesting.
I gave you the numbers of several highly regarded stats, and his ranking among the top 200 RP'ers from 2017-2020 was very good in many of the stats and so-so in a couple others, like WHIP. Did you bother to look at the numbers?
If you want o evaluate a RP you have to see his run prevention estimators, because in the end you want to hold and/or minimize the damage when a RP comes in.
Yes, OPS against is proven to be one of the best run prevention stats available. Barnes had very good OPS Against numbers from 2017-2020. Are you saying those numbers are wrong or don't relate well to run prevention?
The fac is Barnes was one of the top set up men in MLB from 2017-2020 combined. If you don't think that means "very good," I'm not sure what else I can say.
His SIERA last year which considers balls in play was 4, very close to his ERA. His 2020 xFIP which normalizes HRs was 4 as well. His FIP? almost 5. His peripherals weren't good as well.
2020 was shortened season. If that's all you are going by, then you have a point. Most GMs do not go by a pitchers most recent 23 IP alone. Even in 2020, his OPS Against was .705, and that was his worst from 2017-2020. Most of teh time he was near or under .680, which is very good, right?
In my book before 2021 Matt Barnes has been an average to just above average RP at best. Never very good as you are suggesting.
Now, it's "never very good?"
He was clearly very good from 2017-2019. Three years of 65+ IP very good set-up pitching.
BTW, I never said he was elite pre-2021, just very good from 2017-2020.Maybe we disagree on what very good means. He clearly was much better than average.
Is .680 very good, or not? How about .660? .650?
Here are his OPS Against numbers since 2017
.655 Very Good
.624 Fantastic
.666 Very Good
.706 Okay (2020 40% season)
Broken down by half seasons:
.629 Fantastic
.688 Good
.509 Spectacular
.844 Bad
.607 Good
.639 Very Good
.706 Okay (2020)
In the playoffs:
0.87 ERA (Your stat of choice not mine- and "clutch")
1.161 WHIP
You seriously think he was "never very good?"
