Yes it is. If the players supplied by the GM aren't that good, it's totally possible. The players could reach their low potential, the coach could get the most out of them, and the GM would subsequently be at fault.
It would be like giving a jockey a donkey and yelling at both of them for not winning the race.
Ultimately I don't think it's that simple, though. We have players on this team that aren't meeting expectations, the new coach has yet to string together consistent offense, and the general manager has left a gaping hole on the blueline for years. You can't isolate and change one thing that would flip everything around. There's a synergistic relationship.
If I'm Ken Holland though, I look at the blueline and go from there. If you get the blueline to where you think it should be and things are still rough, then you start moving down the line of other potential issues.
If only we had a comparison to go off of as a base line
Babcock and Holland seemed to have fundamental disagreements on how the team should be run. Babcock is definitely better off being where he can do a rebuild around his philosophy. As for Detroit? Who knows, this is Babcock and Holland's team, not Bashill's.
For someone who calls themself 'Actual Thought' you seem to misconstrue what people are saying a lot. It's pretty obvious that you can have all the right people in an organization and if it's leadership at the top is ineffective that it can sink the rest of the organization. This team has a lot of good players, but players being brought in, those being retained, and those being drafted don't seem to point to a coherent plan coming from the front office. This team hasn't been able to address any of the major issues facing this team going forward: Lack of any defensive depth in the prospect pool, the lack of a elite defensive players, and lack of young center depth. Instead the team has thrown away prospects and picks for plugs. The only real strategy that Holland has shown is that he wants to continue the streak. Until Holland either rights the ship and commits to actually contending or he is gone this team shows no indication of contention in the near future.
So TLDR yes, you can't win a cup with a good coach and a good players if the management isn't able to address deficiencies and has shown a lack of a clear plan.
This is where I point out what Holland has done and you come back and say those players suck, first rd exits, ect... Your responses will most likely be condescending.
We now have an elite goalie prospect.
We now have an elite center prospect with elite speed.
We now have an elite right handed PMD.
We now have an elite shut down Dman who can put up a few points.
We now have 2 25+ goal 50pt+ wingers and a similar prospect.
We now have an elite shut down center
We now have a 20+ goal power forward
We now have a young top 6/9 center with size
We now have a young top 6/9 center prospect with elite speed and size.
All of these players added since 2011-12 season. I would call that significant progress on a team building process.
All of these players are playing at a level less than what they have played before with the exception of those who have no previous NHL experience.
