Sure it does, in terms of dynamic. How can you say no relevance when the greatest players in the history of this game fail to score in a game 7 all the marbles game? The pressure is beyond immense. When you compound that with NHL level officiating, With 7-11 ice, and against a premium goalie and its a special kind of hell trying to create a goal. Teams get few chances in SC final game 7's.
That pressure if felt by anybody no matter the year, decade, etc. Dynamics are like that in that they can be static, but salient variables through time.
