It worked, once. That is proof?
He yanked many a pitcher early, when they needed to be yanked, and they were way below 90 pitches.
I agreed on some times I wondered why he pulled a guy that seemed to be doing well, but stated we don't and didn't have all the facts. Maybe, they noticed something we didn't. Maybe even the pitcher said something we didn't hear, or the catcher commented that the guy was losing it. Maybe the guy was on a pitch count for a good reason, we didn't know about. Maybe Bello is still pitching well, precisely because we yanked him early a few times.
We just don't know all the facts and what ifs.
I do know that during the game threads, I see a lot of , "Cora should have yanked ____," said right after a homer of bases loaded walk. We also see many times a pitcher looks horrible, then pitches 3-4 nice innings after some were screaming he be yanked. We forget about those choices made more than we remember the choices that did not work out.
I have no issues with Cora's in game pitching choices. I question some moves, but not any more than other managers, and probably less.
He's had to start our 8th, 10th and 12th slotted SP'ers way too often. He was handed a highly questioned pen, and they have the 4th best fWAR in MLB. To me, how he's handled the staff is his strongest point in favor of not being terminated.
We just have to agree to disagree. Yes, he's made mistakes. He'd agree, too.
To me, he's done more good than bad, and the team just hasn't responded, key players were hurt or traded away. If I gotta blame someone, it's the players, JH and then maybe Brez. Cora is way down on my blame list.
