Historically home ice has been viewed as an advantage although studies don't always support that belief. Yet so far in the Stanley Cup playoffs home ice has been no advantage at all. Only 14 home teams have won so far out of 33 games played. That a rate of 42.4%. Both Boston and Montreal have only won on the road. In both the Pittsburgh-Tampa Bay and San Jose-Los Angeles series, road teams have won 3 out 4 games so far.
In the 2009-10 NHL playoffs home teams won 52.8% of the games. In 2008-09 the winning percentage of home teams was 59.8%. Not sure what is happening here but in three season we have gone from almost 60% advantage for the home team to almost 60% advantage to the visitors.
