There is an awful lot of talent on that roster, anyone paying attention can see it. This is how I know the issues are above what's happening on the ice. Like
@Uncle Scrooge said it could be something as simple as them just not having fun anymore. If that's the case Sutter definitely isn't the answer
Time will tell, but I just don't see what Treliving has done to keep his position. Giving him the green light to hire his own coach has he's about to enter his 8th season as GM with his 5th coach (yes I know shit went down with Peters). Like I said, they were better off riding out the season and cleaning house in the off-season. There is too much high-end talent on that roster to be sputtering out like this. Either fix management or trade the lot of them and try a true rebuild, not an accelerated one. We've seen time and time again that those don't work, and although they can bring short term success, that approach won't win you cups.
