When hockey fans think of the most hated people in NHL history, the focus is usually on the players.
Occasionally however, it shifts to people on the other side of the game. Coaches, general managers, referees, television personalities and a certain commissioner who has locked out the league three times have all felt the hate from fans.
Whether it's a bad trade by a GM or the way a coach has acted with the media, all these people have done something that has drawn the ire of fans. It could just be from a singular team's fan base or it could be felt league-wide.
Whatever the reason, these people have more than a few people not on their side.
