People who have never led or managed people tend to believe that yelling all the time is effective for some reason.
I don’t even care about the yelling although you are right that would never fly now (as evidenced by his lack of sucess).
But it is annoying to hold him as the gold standard even though he had 2 amazing years but 3 bad and/or rebuilding years. And people want prohm fired for 1 rebuild/bad year.
