I think the main improvement is depth and the addition of Garland and (hopefully) Podkolzin and you're underrating their possible impact. Instead of picking up guys like Vesey and Boyd on waivers the team is starting off with guys like that in the system. A player like Michaelis shouldn't get 15 game opportunity to put up 0s. So I think they are improved up front. Saying Dickinson is not as good of a goal scorer as Virtanen and a step back from Beagle's FO ability underscores the fact that Virtanen scored 5 goals and had 0 assists last season and Beagle was a 35 year old player tasked with 80+% zone starts.
I mean what was the Canucks' 3rd line to start last season? Gaudette/Sutter, Roussel, and Virtanen? Gaudette and Virtanen on the 3rd line might have sounded good on paper but in reality it was not. You don't think Dickinson, Pearson/Hoglander, and Pods will be better?
I don't think the D is better with the loss of Schmidt. But there's some hope that OEL can be better than what Edler was last season and I'm excited to see Rathbone play a full season. There's once again more depth. No Chatfield for Green to keep playing might end up having a sizable impact.
