Complaining about refereeing is usually a lame and tired excuse when a team is struggling. In most cases, it's fans or players looking for excuses for a loss or a poor effort. Last night there were certainly some questionable calls but this isn't a new thing for this Islanders team.
When you take a look back at the entire league and the amount of power play chances, the league average is roughly 140 power play chances. Every single team, except for one has over 100 power play opportunities, that one team is the New York Islanders.
