Those Especially Special Teams

There I was, idly clicking my way around the hockey blogosphere, when, like the Bat Signal cast against the cloudy skies of Gotham, I spied a call for help. At the end of a post covering the All-Star Game and how perhaps it might be improved, Ritch from American Hockey Fan had a question...

Why not have the best Powerplay in the league face off against the best PK? Who would that be, I wonder? San Jose vs. Montreal, maybe? Perhaps the Forechecker will come to my aid again.

Fear not, good netizen - I'm always in need of topical inspiration, so let's take a look...

The NHL stat in this area merely covers percentage of opportunities converted. On that front, San Jose has the top power play (25.8%), and Vancouver the top penalty kill (88.4%). There, we have our answer, right? If we did, this would be an awfully short piece, that's for sure.

A great source of special teams statistics can be found over at mc79hockey.com, where you can find a breakdown of teams on a 60-minute basis (note: mc79hockey's stats are currently updated through Game 472, which is a few weeks old). In other words, given 60 minutes of power play time, it shows how many shots and goals are being racked up (for and against) by the various teams. Looking at power play numbers as an example, if you take Goals For/60 Minutes, and subtract Goals Against/60 Minutes (due to shorthanded goals allowed), you get a Goal Differential/60 Minutes. This gets us past the two major flaws in the NHL's basic power play figures, which only reflect percentage of opportunities converted. First, due to penalties being called at different times, you can have a PP lasting only a few seconds, but it counts in the NHL figure just as if it was a full five-minute major. Therefore, normalizing the power play output against a standard time period gives a better picture of actual production. Secondly, there is no consideration for a sloppy power play that gives up shorthanded goals, or an opportunistic PK that scores some of their own. I took the liberty of updating the Goal Differential/60 Minutes figure, which is indicated in the table below:

Indeed, San Jose is way out in front with the man advantage, followed by Montreal, Anaheim, and then the bulk of the NHL grouped in a range from just under 5.00 to 6.33 Goals per 60 Minutes. You really see the Goal Differential factor come into play towards the bottom of these standings, where a team like Edmonton jumps several places compared to their typical NHL Power Play ranking, because the other teams around them give up so many more shorthanded goals. Similarly, those young Pittsburgh Penguins have given up seven shorthanded scores against, which drops them behind four other teams with fewer PP Goals For.

On the PK side, we see Montreal on top (1st in PK, 2nd in PP, no wonder they're doing so well), followed by Minnesota and Vancouver as the only teams with a Goal Differential/60 Minutes better than -4.00. According to the typical Penalty Killing percentage, the Canadiens would only be third, but on the strength of 10* shorthanded goals, they, along with the Wild (with 8 SH goals) pull ahead of the Canucks, who only have two such scores.

So, Ritch, in your dream matchup of top power play vs. top penalty kill, I'd indeed recommend pitting San Jose against Montreal. A possible extension of this analysis could look into the Shot Quality produced during these situations, to help separate the performance of the goaltender from that of the forwards and defense. For example, even though the Nashville Predators are fifth in this PK Ranking, I'd suspect much of the credit should go to Tomas Vokoun and Chris Mason, who have been spectacular all season long. On the opposite end of that scale, we may find that there are skaters on teams at the bottom of these rankings that are giving up relatively few scoring opportunities, but goaltending (hello, L.A.) is letting them down - and a savvy GM might want to look for that kind of player to help complement a team that hopes to make a run in the playoffs this spring.

*remember, I tend not to count empty-net scores in my analysis.

How I'm Trying To Make Money Sports Blogging

To kick off this series of articles general sports-blogging articles here at OTF Classic, I think it's best to start with a comment that Brad left here last week, after I shared my goals for 2012, which include specific revenue targets:
I considered diving into the world of internet marketing myself, but I felt that my friends would hate me for bugging them about stuff. I mean, it's pretty low-risk high-reward, so it's tempting. I wouldn't mind reading about tips on how to maximize impact of blogging in general to make it a legitimate income source. Trying to make money at sports blogging can be a very touchy subject - for the vast majority of us, this is an activity we pursue to both exercise our creativity and share our love of the game, whether it's hockey, football, badminton, whatever, with fellow fans. Mixing that personal conversation with a commercial message can turn people off, especially if it becomes too intrusive for the reader.

Hooray for PythagenPuck

Back in November, around the quarter-mark of the NHL regular season, I wrote a piece looking at Expected Winning Percentages for each team, based on their Goals For/Goals Against ratio, using the PythagenPuck method as outlined in Alan Ryder's "Win Probabilities" article over at Hockey Analytics. Since we're approaching the end of the campaign, I thought it worth revisiting the two assertions I made back in November - that the Ottawa Senators were capable of getting back into the playoff race, and that the Boston Bruins were in danger of a freefall to the bottom of the standings.

Just to review, the basic idea behind win probability models like PythagenPuck is that over the course of a season, the Goals For and Goals Against numbers can be used to derive a team's winning percentage, within a a surprisingly narrow margin of error. For instance, if you only had GF/GA information, you could make a very good stab at projecting what the standings would look like. The w…

Where are my tickets, Mr. Holland?

While working on a piece about the 10th anniversary of the great Colorado/Detroit game at Joe Louis Arena, I caught myself reflecting on some of the great games I've had the fortune of seeing in Detroit during the 1990's, through a variety of means. Then another thing came to mind - when I'm in attendance, the Red Wings win. I'm on a huge personal winning streak here, so perhaps the Red Wings front office would want to bolster their chances during the upcoming playoffs and make sure I'm in the house for those critical games? I can make myself available...

June 4, 1995: Detroit takes Game 2 of the Western Conference Finals from Chicago, 3-2 (although the Hawks put one of the goalpost as the final horn sounds). Wow, has it been that long since the Blackhawks achieved anything? Ticket courtesy of a college buddy who had a spare.
