I think we need to keep in mind how many disappointing years we had with the sedins we had before they took the league by storm.
My cousins watched every game and regularly participated in a drinking game in which you had to chug a beer every time either Sedin fell on the ice. They would be drunk by the first period as they got manhandled.
Years later their cycle game finally translated from the SHL to the NHL and they were the most dominant duo in the league and got to enjoy that for a few years.
This core needs 2-4 years as a group to step into what they are to become. What that is isn’t certain but I do believe at some point we will see this core click and take a dominating step forward.
