Cleveland fans have always wanted a hot head on the sideline to turn into angry dad and reflect how they’re feeling when things are going badly. They think that cartoonish football coach blowing his stack cliche is what real leadership looks like. Personally I don’t want the general of my army ever drunk on his emotions. I’ll always take a level headed cool cucumber, Tom Landry type thank you very much. Especially when things are going badly. You need the center to be steady.
Those people just want to be entertained by the idiot box. Their coach needs to fit their desire for the character in the show they're imagining.
It doesn't matter, at all, in any way, whether the coach shows fire or is the most silent & stoic statue you've ever witnessed. The ONLY thing that matters is whether or not he is a leader and how the players respond to his leadership.
