You don't understand the importance of a supporting cast then.
Virtanen may not end up becoming a star, that doesn't mean these players aren't a critical part of a Stanley Cup winner. You're ignoring how important the Bruins and Kings physical game was to them winning.
Lucic and Horton were huge parts of their run, not mention Recchi. The whole team played a north-south game. The same game Virtanen plays. Brown, Richards, and Williams all play the same straight line game too.
