"The refs have it in for us!" - Is there any truth to this statement?

UPDATE (OCT 28th) - 11 games into the season and Ottawa still haven't played one game in which they have had more power plays than their opponent.  They are now -33:18, still almost double the 29th place team.  They are also one of 3 NHL teams that have not had 1 second of 5-on-3 time.  Colorado meanwhile, have plummeted from 6th down to 26th in PP-PK time, upholding their unenviable trend from the past 4 seasons.

As a Senators fan who recognizes my own bias, I sometimes think that I am guilty of discounting legitimate issues, attributing my concerns to my own fan allegiances.  But after watching another game in which it seemed the Ottawa Senators could not buy a powerplay, I started trying to remember the last times the Senators played a game in which they had more powerplays than the opposition.  It hasn't happened in 5 games this season (BUF 4-3, TOR 6-1, LAK 6-4, SJ 5-3, ANA 5-1).  And come to think of it, it hasn't happened very often, in a long time.  It seemed like I had to go back to the days of Jacques Martin, when Ottawa was winning Presidents trophies, when Ottawa was spending more time on a regular basis on the attack rather than penalty killing.

So I started doing some digging, and the statistics are actually quite shocking.  In this case perception is reality.  There are two teams that would seem to have reason to ask questions about the consistency with which they find themselves being penalized and not getting powerplays.

These two teams are Ottawa and Colorado.

I used the Powerplay time to Penalty Kill time gap as the preferred indicator, and stats are recent up to the morning of Monday October 14th.  The PP:PK time stat is not without its flaws: Teams that score early into powerplays would decrease their PP time, and teams that allow goals early in penalty kills would decrease their PK time.  But it accurately allows us to overlook the meaningless penalties assessed in the dying seconds of a game, when the teams don't actually gain an advantage, and also accounts for "neutralized powerplays", when a team has a powerplay cut short by being assessed a penalty during their own powerplay.  Most importantly, the focus on the gap means that it is looking both at penalties taken, and power plays awarded.  A team could be a "dirty" team that takes lots of penalties or gets assessed lots of fighting majors, but this team could also be receiving an offsetting amount of powerplays and still have a small gap.

So here are some highlights (or maybe lowlights!):


  • The Ottawa Senators have not had a season in which they had more Powerplay time than Penalty Kill time since 2006-2007
  • Between 2007-2008 and 2013-2014, the Ottawa Senators have spent 352 more minutes killing penalties than playing with a man advantage (This is just shy of 6 full games).  The Colorado Avalanche, during the same stretch spent 103 minutes more killing penalties than playing on the PP.
  • In the 2011-2012 season, the Colorado Avalanche were in a league of their own, with a -114 minute PP : PK gap.  The 29th place team had to kill 34 minutes fewer, and the 1st place team (CBJ) were 216 minutes clear of them at +102.
  • On average, between 2007-2008 and 2013-2014, the Ottawa Senators have found themselves 27th in the league in the PP : PK time statistic, never reaching higher than 22nd in 2008-2009.  Their second highest finish was 27th.  Colorado Avalanche were on average, 18th during the same span, but ranged as high as 4th and as low as 30th.

What does this mean?


First off, allow me to say that I do not think this to be some kind of conspiracy.  I don't think there is any match-fixing going on, especially not for Ottawa or Colorado games.  But sometimes, statistics can tell a story that suggests there may be some latent influence occurring.  Personally, I think that the fan influence during Montreal and Toronto games take away the home ice edge for 6 to 8 of Ottawa's 41 home games, and the yells and screams for penalties from these particularly boisterous groups of away fans probably gain the opponents some calls.  There is also the issue of reputations and rapport with the refs.  We all remember the publicized instance of Dan O'Rourke calling Erik Karlsson a "diver," and of course there were the Cory Clouston years where the young coach demonstrated an inability to bite his lip and let go of the bad calls in the way that Jacques Martin could (to a fault).  During that time, some of our young players followed suit, joining in on the yapping and probably not earning themselves any benefit-of-the-doubt.  Are there other factors at play?  I don't know, but at least I know that I am not crazy now that I have looked up the stats. Let me know what you think.

  1. As an example of how the PP - PK works at identifying teams that are really not getting calls going for them, The Colorado Avalanche in 2011-2012 were miles away from anyone else at -114 minutes in the PP - PK stat. Yet in overall Penalty Kill time, they were only 22nd in the league. Montreal on the other hand, were 30th in the league in total PK time, but were 19th in PP - PK time, meaning that they were getting lots of offsetting calls in their favour, to help them finish 96 minutes clear of Colorado.
