My uncle was a successful high school basketball coach from the late 70s to early 00s. When he had two of his sons (who he had coached) become high school basketball coaches, he took them aside and explained to them that "you cannot do some of the things I did as a coach in this day and age."
You are lying to yourself if you think there were not times K or huckleberry or even Knight (and even going back to the Nose) did not get technicals (or did and wasn't thrown out) when they were warranted for going after refs? And rightly or wrongly, there are things 40+ year head coach can say or do to a team and not only get away with, but motivate a team, that a first year head coach would say or do and could have the opposite affect as intended. K was in this place 40 years ago. He had to earn how much of a hard @ss he could be with his words and actions. He had to earn how much he could really get on officials. Sheyer, or anyone just a new head coach, is going to lose the team or lose respect from officials a lot quicker than from a veteran coach.
Aristotle pointed to three elements of speech to persuade a person: logos (logic), pathos (emotion), and ethos (persuasion simply by who is giving the speech). Sorry, Sheyer (or any first year head coach, save maybe a Bill Guthridge-type who has been an assistant for a long time under a legendary coach) does not have the ethos yet.
Remember 1994-95. Duke lost A LOT of close games. Was it all Gaudett's fault? No. It comes down how do people respond in a close game if they look over and see K versus they don't. How many people could have pulled off "We will win this game" against UK in 1992 or "I don't coach losers" at Louisville in 2019?
Sheyer will find himself. Some of you need to tone it down a bit on him. And remember, a lot of times K going after officials was him picking his moments and it trying to be motivation to the team as much or if not more than bad calls.
