Being an NHL head coach is among the most demanding jobs in professional sports. It can be rewarding, especially when a team is successful. It can also be highly stressful, especially if the club is struggling. The coach almost always gets blamed when the team does poorly and rarely gets credit when it's playing well.
There's a saying that coaches are hired to be fired, which seems to apply to NHL coaches. Most last only a few years with the same team. Some of the most respected, longest-serving NHL coaches have worked for several clubs throughout their careers.
Coaches can be fired for doing a poor job, but sometimes they become scapegoats for management incompetence. Guiding a team to perennial regular-season success is no guarantee of job security if they fail to succeed in the playoffs.
