Coaches typically follow the same patterns. I'd say Berube is here the whole year short of a long losing streak (which, we're on one) or just an unbelievably embarrassing season that doesn't correct itself to some degree (which you could also probably say is happening). Gonna take some more losses or a few huge blowouts or so before it's at that point.
Hextall is also a patient man and smart man with a vision for the future it seems, so he's the wildcard there but I could see him keeping Berube the whole year even if he wants to ditch him. Snider is a different story, but we'll see.
One reason Lavy was dismissed was also because the younger players 'weren't developing,' while Gus plays in Russia, Akeson is chained in Berube's basement, and Couturier is expected to be a scorer as he's buried with defensive zone starts.
This is a really good point that isn't talked about enough actually. It's very important that we don't damage the development of players here and so far Gustafsson was just crazily treated then left for Europe, Akeson is in developmental hell right now getting a lot of time either scratched or in depth roles not suited for him (not to mention the fact that our bottom lines inherently suck), Couturier isn't being given any sort of shot at consistent offensive opportunity, Schenn gets thrown around on lines like a rag doll, and Laughton is probably ready for the big club yet hasn't seen any action until recently a losing streak prompted and he's
still not getting the minutes he deserves.
So, that's all very bad. It's also extremely counter-productive and counter-intuitive to this whole "build for the future, be patient" thing we should and are supposed to have going on.
