The Importance of Game One

Here's a stat for you:

Since the NHL adopted the current conference-based playoff format in 1993-94, clubs winning Game 1 have gone on to win the series 133 of 195 times, or 68.2% (all series best-of-seven). For the Conference Quarter-Finals only, clubs winning Game 1 have won 74 of 104 series (71.2%).

Which leads me to a question I ponder every year at playoff time - which game in a best of 7 series is the most pivotal to win? Obviously game 7, but maybe you have some thoughts on this. Share them in the comments section!
