I've always found it interesting that habits like yelling and losing your temper that would get you fired if you were a manager/coach/instructor in any other field are considered a positive trait for athletic coaches.
If you were teaching medical students would you scream in their faces while they worked on a cadaver?
You're rightly labeled a socoiopath and ushered out the door if you're a banker or law partner who berates their associates in front of a client.
And you would be looked at like a crazy person if you threw a clipboard or headset during a meeting in any office in america.
Critical review is one thing. But the theatrics and yelling wouldn't be acceptable in any other field. Sports doesn't exactly pick from the cream of the management crop though so I'm not exactly surprised.
Kinda comparing apples to oranges. Doctors, lawyers, and businessmen aren't relying on physical performance and adrenaline to do their job. Yelling can be a way to motivate these things in people.
I.E. - If you're weightlifting and Betty White is calmly asking you to try a little harder to lift that weight, is that going to help as much as Conor McGregor screaming in your face that if you don't lift that ****ing bar he will literally ram it down your throat?
