I am not a huge hockey fan, but last Friday night I watched the Pens beat the Red Wings for the Stanley Cup. My wife asked why I was watching hockey and I said it was a game 7 and I hadn't seen a game seven in a while. So that got me looking into the number of game sevens in the 3 sports that play a best of 7 series for their finals. Here are the results of the finals since 1947 (which is when baseball, basketball and hockey each played a best of seven series).
|Total Game 7s||16||25||13|
|Average Length of Series||5.76||5.84||5.42|
|Average Series Length Last 20 years||5.45||5.3||5.6|
|Average Series Length Last 10 years||5.4||5.1||6.3|
|Last time Game 7 Played||2004-2005||2002||2008-2009|
Hockey has been averaging between a 6 and 7 game series over the the last ten years, while baseball has just barely averaged over 5 games. These are contradictory to their historic trend where MLB has seen almost twice as many game sevens since 1947 as the NHL. The NBA Finals have maintain a constant ~5.5 game series over the 3 time frames examined.
