19th, 13th, 23rd, and 14th are not positions to be proud of in any aspect of life. But those positions are where the Dallas Stars ended last season in power play percentage, shorthanded goals scored, short handed goals against, and penalty kill percentage.
And by the way, those numbers average out to a little more than 17th, which is surprisingly close to where the Stars ended up last year in total points (that number is closer to 19th).
But, for how little time per game that a team is on the power play (6-7 minutes) per game, 20% of all goals are scored in that time frame.
