The Pittsburgh Penguins are well on their way to a back-to-back Stanley Cup wins.

By prevailing in the opening two games of the final against the Nashville Predators, the odds of finishing the job for the second year in a row are ever in their favor.

Here's a look at a few numbers to back that up:

50: Since the final went to the best-of-seven format in 1939, 50 teams have taken a 2-0 series lead.

5: Number of teams in that time to win the Cup after dropping the opening two games. That gives the Predators only a 10 percent chance of making a comeback.

But wait, there's more.

37: Of those 50 teams, 37 Cup finalists built a 2-0 series lead at home.

34: Teams that have gone on to win the Cup after taking a 2-0 series lead at home. This increases Pittsburgh's chances of winning to 92 percent.

3: Of the 45 teams that have won the Cup after taking a 2-0 series lead, the list includes the last three: the Los Angeles Kings (2012, 2014) and last year's Penguins.

However, a few other numbers suggest there's some hope for the Predators.

2: On two occasions in the past eight years, a team has lost the first two games of the final on the road and went on to win the Cup. The Penguins pulled off the feat against the Detroit Red Wings in 2009, and the Boston Bruins did it against the Vancouver Canucks in 2011.

7-1: Nashville's record on home ice this postseason.

64-39: The difference in shots for and against in favor of the Predators over the first two games of the series.

One number in particular must change in order for the Predators to have any chance.

.778: Pekka Rinne's save percentage in the Cup Final. If neither he nor Juuse Saros (if called upon) can drastically improve that stat, this series could be over in the fewest number of games necessary.
