This is a symptom of an organization in disarray. You have a president who has zero NHL experience at that level and a GM who rode the wave of success of his superior in Boston. Then, you say you want to win and rebuild at the same time. Well boys, sorry, you can't do both.
I never thought Desjardins was a great coach, not even in junior hockey, but you can't pin all of this on him. If the Canucks want long term success, they are going to have to tear it all down, trade their veterans, and rebuild from the ground up. Problem is, this fan base won't let them. With so many disappointments from this franchise over the 45+ years of existence, they are afraid that too many losing seasons will alienate their fan base for good. They are stuck between a rock and a hard place and don't have the personnel with the smarts to get them out of it.
PS Gerard Gallant should be their next coach
