NHL Numbers previously published a couple of articles on zone entry tracking. We first looked at the results in Flyers games from 2011-12, observing that shot differential at 5-on-5 appears to be largely determined by neutral zone play, and that retaining possession as a team enters the offensive zone is particularly important, generating more than twice as much offense as a dump-and-chase play.
We then called for volunteers to join the project and have had a number of people contribute. We have expanded our database to include a full season of data from the Wild, a half-season of data from the Sabres, a half-season of data from the Capitals, and over 100 assorted games from other teams in 2011-12. This has allowed us to further generalize and strengthen our conclusions for a paper that will be presented at the MIT Sloan Sports Analytics Conference.

After the jump: the single-biggest story in the NHL last week, a mess of trades, injuries, and trade rumours, how bloggers are once again undermining Western society, and Graphic Comments. Also - and this is important - the Winnipeg Jets' all-time greatest moustaches.

Hey, you lovebirds. We can't think of anything more perfect than for you and your loved to spend Valentine's Day listening to two bros discuss #fancystats. Trust us. In this week's episode, we take a look at the curious cases of the Edmonton Oilers and Montreal Canadiens, and try to figure out which teams are due for better/worse luck in the coming weeks.
We would love to hear from you, the listener, for suggestions on future topics of discussion. Rather than us just being in our own little world, we'd like to make this as interactive a show as possible. Feel free to tweet at either Dimitri or Cam.

PDO doesn't stand for anything, but that doesn't mean we can't learn anything from adding up the overall shooting and save percentages for a team at even strength. A layman's explanation for 'PDO' and why we use it can be found here over at the Backhand Shelf. Basically, if a team is playing with a PDO number way higher than 1.000, they're producing above their expected output. If a team is playing with a PDO number below 1.000, they're producing below their expected output. Over the course of a long season, the number will generally correct itself.
No website offers Team PDO as a sortable statistic, but behindthenet.ca has a page that offers a team's shooting percentage and a team's save percentage numbers. Shooting percentage is the 17th column from the left on BTN's team shots page—the first one to say SPCT. It's cousin, team save percentage, is three columns to the right also saying SPCT. The team shooting percentage needs to be subtracted from 1000 to get the actual number.
Here are the team PDO standings through games played Sunday night:
