The whole front office is to blame. But are you honestly telling me Trotz can win a Cup with this squad???
Then it is a coach problem
Agree with Alta that Trotz must quit.
First of all,he has been managing this for many seasons,in fact the maximum result for him was 1/4 playoffs.
Second,it’s main coach assignment to make all these star players play as a whole organism.
Lastly, looking on other teams who have won Stanley cup in past,they also had some star players with unpredictable characters ,however it was the main job by main coach to motivate them and played hard.
