The game has changed a lot in the past century, and some of the men on this list are reasons that the game has changed the way that it has. But there's one thing that will never change in the NHL, and that's that you won't be able to consistently compete -- or win a Stanley Cup -- without a great coach.
Now, some of you might be surprised that you won't see Toe Blake or Punch Imlach on this list, and while they and a few others were tremendous coaches in the Original Six era, they didn't have the same impact. None of them changed the game or revolutionized it the way the guys on my list did.
Here are my top five greatest coaches in NHL history:
5. Roger Neilson -- Many people will say Neilson didn't win much, and it's true he never won a Stanley Cup as a head coach -- he only reached the Final once -- but Neilson changed the way coaching was done. He was incredibly influential and innovative in ways the game had never seen. He was the first guy ever to study film, his practices were well thought out and much more organized than practices had been at the time, and the guys that played for him, Darryl Sittler, Dan Maloney, guys I played with in Toronto that had played for Roger loved him. They all talked about how creative he was.
One of the best things about Roger was how he would always look for ways to exploit the rule book, like when he famously had his goaltender leave his stick on the goal line after being pulled for an extra attacker because there was no explicit rule against it. They had to make rules to combat Roger's thinking. He was influential for workouts, nutrition and a number of other things, but really his use of video might be his greatest legacy. If you go into an NHL dressing room you can't imagine the money and time tied up in video, and that all started with Roger Neilson.
