If you run down the list of the past Stanley Cup champions, they are all related in how their teams are built: Strong goaltending, a superstar core, and the supporting players around chipping in their worth.
The Pittsburgh Penguins and Chicago Blackhawks built dynasties by building young cores and surrounding them with complementary players that changed almost year by year.
The Vancouver Canucks have found their nucleus of young players. Bo Horvat, Brock Boeser, Elias Pettersson, J.T. Miller, Quinn Hughes and Jacob Markstrom is a great core to start with.
