23. John Tortorella
Tortorella is infamously volatile. The hockey coach led the likes of the Columbus Blue Jackets and the New York Rangers. His teams often established superb regular-season records. However, this never translated to postseason success. Despite this, he was a two-time NHL Coach of the Year. When he’s not feuding with the media or fans, he’s actually good at his job.

One of the wackiest incidents was his confrontation with Larry Brooks. Here, he threatened to fight the journalist. He also threw a water bottle at Canucks fans. However, his piece de resistance was when he confronted Calgary’s Bob Hartley. Players and staff literally dragged him away as he attempted to attack his opposite number.
