Mostly when I write about hockey stats, I pull data for 5v5. It isn't that situations with the man advantage (or shorthanded depending on the perspective) are not important. I pull 5v5 data because I need to keep the data consistent for comparative purposes. So I use events that occur only during 5v5 play. So what if we used 5v5 goals to determine the winner of each game?
I pulled all the 5v5 game data from War on Ice from the beginning of the season through the end of 12/16/2015. For each game a team played if they had more goals for at 5v5 than goals against, they received two points.
