I certainly will give Therrien his chance. He isn't the same coach he was 14 years ago, and he certainly is nothing like JM or RC.
I don't mind him trying to get through to PK. I want PK to be enthusiast, and yet manage to draw this team together. If Subban is to be part of our long-term core, he'll have to strike the proper balance between his enthusiasm and exuberance.
Unless you break his character (which I hope will never happen), PK will create ripples in any locker room he goes through. He should find a way to make these ripples a positive rather than an annoyance.
