21. Bobby Knight
Knight is a Hoosiers icon but it’s safe to describe his coaching style as ‘old school.’ It’s unlikely that he’d earn a coaching job in the modern sport because of his toughness. Knight had an unforgiving personality and was ruthless toward his young charges (via Yahoo). Famously, he threw a chair in one game.

In 1997, he became embroiled in one of his biggest scandals. One of his players accused Knight of choking him. Later, a video emerged that supported this claim. This left Knight on thin ice. Finally, he lost his job after he grabbed another student and verbally abused him.
