The post of DAChamion was right. Whatever where you put Makar, I mean Bolts, Kings and Hawks won 2 or 3 SC without a single generation player. They had a good mix of very good players, applying a strong system and dedicated to the game. Same happened with Canes, Bruins and Blues when they won the SC.
Being that said, Habs can build a SC winning team without Bédard. Oilers have 3 FOA draft with McDavid, Draisaitl and RNH and they haven't won anything. McDavid is obviously a generation player. A team who wins the SC have more than that. Crosby alone can't win, same with any generation player.
Hockey is a team sport, I will never write it enough, I become redundant, lol.
