You don't win in MLB by pissing off your players by calling them out in the media. Knorr will learn that if he becomes the manager.
The below quote on Harper from today's piece by Kilgore shows a particular heavy handedness. And I'm a Knorr guy
“That’s just him,” Knorr said. “He’s just 20, and sometimes, he just pouts. Sometimes, he pouts. I don’t know why. That’s the thing about him. You can’t be this guy who says you’re going to play hard every time out and then not do it. You can’t do that. He’ll learn that. He’ll get better with it. He’s 20 years old. He’s still a kid, and sometimes kids pout if things don’t go their way.”
