My point is, you guys are making the correlation between high K rates and the end result of getting more guys out. Then, you are saying that because they are often, but not always related, then high Ks should be used to judge the final output.
I'm saying judge the final output. If someone's got a high LD% and low BABIP number or some other indicator that he is getting lucky or getting away with allowing more balls put in play due to superior defense than who you are comparing him to, then I get it, but that's not the case here.
I brought up the BB/K rate as a stat that can be used and "correlated" the same way Ks are. Most pitchers with great BB/K rates end up with great outputs, so naturally that stat should then be used as part of the judgement of the output. It's nonsense.
Pitchers get guys out in many ways. I get the argument that forcing the defense to help make the out often will lead to more hits, but when it doesn't, why hold it against the pitcher? Plus, Porcello walks less batters, and that more BBs puts men on base without the defense having a say in the matter. It's all on the pitcher (maybe some on the catcher?).
Porcello let up less hits + walks per inning than anyone but Verlander (by 0.01).
Porcello has the best park and opponent adjusted ERA (ERA-)..
That's the output
That's the bottom line. He did it by walking less batters. He did it by allowing less runs than expected by playing in more hitters' parks and facing way tougher teams and offenses (ERA- proves that point).
Maybe If Porcello played on the Guardians, who have a better defense, play in more of a pitcher's park, and face easier opponents, he'd have more Ks, less hits allowed and a better ERA and K/9 rate.
