In the NHL, it seems as though coaches come and go as often as rule changes.
Coaching changes offer a much-needed jolt to the team and sometimes even a change in identity.
A perfect example of this is Pittsburgh Penguins head coach Dan Bylsma, who was hired because the team needed a different look. This change was an instant success, and the team went on to win the Stanley Cup that season.
The trend seems to be that coaches are hired from within the team's organization, commonly the team's AHL head coach (Bylsma, Joe Sacco, Bruce Boudreau and Cory Clouston are examples).
This trend has left many established veteran coaches either without jobs or starting over with minor-league teams.
Here is a list of the top seven head coaches currently without jobs in the NHL.
