Stanley Cup Final was most viewed non-Original Six series in 15 years

Maybe it was the massive beards, maybe it was Sidney Crosby, but whatever it was, plenty of people tuned into the Pittsburgh Penguins' bout versus the San Jose Sharks in the Stanley Cup Final.

The NHL's concluding series was the most watched non-Original Six series in 15 years, averaging nearly 4 million viewers per game on NBC.

Sunday's Game 6 - a 3-1 Cup-clinching Penguins win - drew 5.407 million viewers, NBC's highest number for a non-Original Six Stanley Cup Final game ever.
