So much of a coaching career is tied up in opportunity and timing. I don't think Maurice was any kind of failure here, the sands just shifted under him and it was time to move on. Good on him for finding another NHL gig; I expect we'll be seeing him in the league for a long time, in one capacity or another.
I was mostly neutral to Maurice, just as I am Muller, but I just don't understand what makes Maurice so much worse than Laviolette and/or Muller. Can't really compare him to anyone else, since no one else has ever coached a JR-conceived roster.
