Even if the impact of power plays has decreased in recent seasons, down to 3.66 opportunities per game this season from a high of 5.85 per game in 2005-2006 coming out of the lockout, it remains an important factor in determining the outcome of a game.
Here is a look at the best and worst individual power play performers so far this season.
Some observations from the charts below:
Teemu Selanne and Daniel Sedin aren't particularly surprising at the top of the ledger, since Sedin leads the league in power play points, with 31, and Selanne is seventh, with 24 points, and the only one among the league's top 30 in power play points to not have played in 50 games yet this season.
Habs call-up David Desharnais has made an instant impact with the man advantage, scoring three goals and two assists in 38:02; perhaps an indication that he may deserve more time on the PP.
Manny Malhotra gets very little power play time (42 seconds per game), but has had some success, which may be more of a credit to the Canucks power play as a whole rather than an indication that Malhotra ought to be pushing the incumbents on the league's best power play.
There are a few other checkers that found there way onto the list. Tyler Kennedy, Brian Boyle and David Bolland are among those who might be considered surprisingly effective in limited power play oppotunities.
At the other end of the spectrum, Christopher Higgins has played 60:50 on the power play this season without registering a point.
There are other disappointments among the bottom producing forwards, like Alexander Frolov (or injured players like Zach Parise and David Perron), but many of those included wouldn't necessarily be expected to produce big numbers.
In order to measure each player's power play contribution, I've counted goals at the equivalent of 1.6 assists and then taken the resulting production on the basis of 60 minutes of power play time.
Players must have played at least 1700 seconds (28:20), which would account for about half a minute of power play time per game to this point in the season.
Even so, some of the outliers at the top and bottom of each group can surely be attributed to the small sample size if they haven't played that much on the power play.
With that in mind, a look at some of the best and worst on a per 60-minute basis with the man advantage this season.
Considering Vancouver's success on the power play this season, it shouldn't be a surprise to see Ehrhoff at the top of the defence list, but three power play points last week (giving him four on the season), lifted seldom-used blaster Milan Jurcina to a shockingly high mark.
Call-up Grant Clitsome has been just what the Blue Jackets needed -- forever, it seems -- managing four power play points (including a couple of goals) in his first 15 NHL games of the season.
Many of the other defencemen on the list are to be expected, but Brett Clark obviously reaped the rewards of playing on the Lightning power play, a spot that is better suited to newcomer Marc-Andre Bergeron. Somehow, that didn't have the same effect for Pavel Kubina, who has been among among the least productive blueliners with the man advantage.
Second-year Rangers defenceman Matt Gilroy has played 62:40 on the power play this season without registering a point, leaving him in the unfortunate position of propping up the rest of the defenders on the chart.
Recently-traded Francois Beauchemin and Luke Schenn, who were No. 3 and No. 4 on the Maple Leafs in power play time for defencemen, have been especially unproductive.
Should Tomas Kaberle be dealt, as oft-rumoured, Schenn will rank only behind Dion Phaneuf among Maple Leafs defencemen in power play time, so an increase in productivity would be imperative.
