A coach's key players, Robinson said, "have to be on your side and willing to cover your back. You have to have good assistants and good people around you. You can't please everybody. There are 23 players and you can only dress 18 and two goalies, so somebody is going to be [unhappy] somewhere along the line.
"It's not an easy job, it took its toll on me and it's taken its toll on other people," said Robinson, who stepped away from the Devils bench consumed by stress and unwilling to put his health at risk. "Unfortunately, a coach is hired to be fired. As they say, it's so much easier to replace one person than it is 18 or 20."
Hockey during his playing days wasn't what it is now, Robinson said, in large part because of the better-educated players of today, the progress of game analysis, agents, endorsements and the like. It all serves to change, and in some ways complicate, a coach's life.
"A lot of players never had agents in my day. A select few did but everybody else didn't know what the heck was going on," Robinson said. "Whatever the GM offered you, you said, 'Yeah, that's great,' as long as you had a job.
"It's not that way now. Everybody knows what everybody else is making and for how long, and there are even restraints on how much you can earn with the salary cap."
What surprised Robinson most about Julien signing on with the Canadiens was that he's landing with a division rival of the Bruins while his chair is still warm in Boston.
"But I guess it all depends on how everything is handled," he said. "The Bruins are getting rid of a salary by letting Claude go to Montreal. It's not always about the person, sometimes it's just about the business."
