Playing with Crosby and IPP

Last month, I looked at something called individual point percentage (IPP) both for forwards and for defensemen. To recap the concept, individual point percentage is a calculation of the number of times an individual player gets a point (either a goal or an assist) relative to the number of total goals scored while he's on the ice. So, for example, if a player is on the ice for fifty goals-for during five-on-five play over the course of the season and he gets a point on forty of them, his individual point percentage at five-on-five would be 80%.

Most forwards end up at about 70% over the long haul, but there are some that buck the trend. Sidney Crosby led the league over the last four seasons with an IPP of 84%. One of the things discussed in the comments to those posts was what kind of impact playing with a guy like Crosby might have. Points are assigned on a zero-sum basis, so if he's getting more, who's getting less?

This new, regular feature on NHLNumbers will share interesting stats-related posts from around the web almost every day.

Welcome to edition number 13 of the rebooted Number Chains. In this space you will be able to find the best analytical hockey writing from around the internet on a close-to-daily basis. Subject matter will include statistical evaluation, financial analysis, contractual issues, and (sometimes) closely-related tangential works. If you have something you would like to submit for a future edition (your writing or that of someone else) feel free to send it to me via Twitter @JoshL1220 or leave a comment.

Jesse Spector's series of crazy lockout-ending ideas continued yesterday with his craziest idea yet: play hockey while negotiating. He goes on to explain:

Get back on the ice, start collecting ticket revenue again, start selling merchandise again, and put the game front and center instead of posturing, browbeating, and greed. It’s not only the best way to set about repairing the NHL’s image, which believe it or not still has not hit rock bottom, it is the best way to make a deal.

Every observer agrees that the best chance to make progress on a collective bargaining agreement is to take negotiations out of the public eye. What better way to do that than to bring back hockey and move the CBA backstage?

It actually isn't a bad idea. Unfortunately, as Jesse points out, Donald Fehr suggested as much in September. Since the players suggested it the chances of the owners going along with it are slim to none.

More #fancystats, fan insulting, and mediation fail after the jump.

Building a NHL Fantasy Predictor: Do NHL Coaches Have Zone Start Trends?

Whether coaches have zone start trends is another question I find that I'm asking myself as I build my fantasy prediction model. We know, for instance, that Alain Vigneault uses a drastic zone start deployment, where his 3rd liners would yield virtually no value for fantasy hockey (though they certainly have real-life value) because they start so much of their time in the defensive zone. Why is this important for me? Well, having identified a pretty stable indicator of the amount of on-ice shots a player will take in %AttSh, and knowing that 1st, 2nd, and 3rd lines have typically different amounts of shots-for per 60 minutes, we also need to remember that a coach might affect those shots-for per 60 minutes by having drastically different zone deployments. After the jump, I'm going to look at this question and see what I can find (and potentially use).

A Corsi-centric Discussion of Advanced Stats

Justin Bourne and I got together to discuss a few things in the realm of hockey analysis recently. The full thing can be found here at Backhand Shelf, but here's a taste of the back and forth :

Kent Wilson:

Perhaps we could discuss this from your latest “Thoughts on Thoughts” piece: “Guys who lose a lot of puck battles end up with poor Corsis, and with the (slight) rise in the prevalence of that stat, I think those guys are going to be more exposed than ever.” Is this something you intuited or is it something that’s been studied? I, personally, assume there could be a relationship there and in fact have thought it would be great if we could track puck battles to see if they correlate with possession (like the way Eric did with zone entries).

Harrison Mooney was able to have more fun writing a post during the lockout than anyone else thus far. On Sunday, the lord's day, Harrison wrote about the booming sex industry in Canada with the lockout in full swing. As he and this quote from the Toronto Sun put it:

According to Vinay Morker, the owner of Edmonton's Hush Lingerie and More boutique, sales of his sex merch have gone up 15% since October. From the Toronto Sun:

"When Oilers fans, mostly guys, have to break their routine of seeing every game, they have more time," Morker said. "And there's nothing better than spending it with your spouse or girlfriend."

Morker said Hush's main clientele is couples looking to "expand their horizons" and he's seen a 15% jump in the sales of their sex toys, lingerie, games and sexual guides, like The Kama Sutra, since October.

The post goes out with a bang and a quasi-salute to our own Eric T when alternative opening lines for the post were discussed:

With no hockey on the schedule, NHL diehards have turned to creating zone entries on their own.

Bravo. We might not have hockey, but we have zone entry sex jokes. Less sex, but more stats and lockout posts are after the jump.
