Coaching Shuffle in NHL

This week, heads rolled in the NHL. The Capitals fired their bench boss, who replaced the Ducks head coach, who was fired after the Hurricanes fired their coach, who was replaced by an AHL coach...Lets slow down for a second. After underachieving and losing his locker room, the Capitals fired former coach of the year Bruce Boudreau. On that same day, the Hurricanes fired (again) Paul Maurice. Boudreau was replaced by former NHL-er Dale Hunter, Maurice was replaced by Kirk Mueller and Boudreau ended up taking the Ducks job in Anaheim two days later after they fired long time coach Randy Carlysle. Theres a shelf life for NHL head coaches, so its a good thing Pittsburgh's coach wont be expiring anytime soon.
