Naahhh pointing out the facts is not bashing.
As I said, using ERA is a solid stat when you use it in career samples. Using ERA for short samples and even in year samples for relievers is terrible specially in order to predict future. I used as well career WAR, career run prevention stats, career peripherals, etc. He was mediocre at most of them based on fangraphs charts.
You were the one who made a bizarre chart that doesn't make sense, not me.
Also, in Barnes' case you can not use SV% ratios because he hasn't been a full-time closer. Common sense.
