Delta Corsi and Assessment of Individual Player Impacts on Possession Accounting for Usage


Statistical analysis of skaters in the NHL (and other hockey leagues) is a difficult and multifaceted process. At this point in the hockey analytics (or #fancystats) community one of the biggest problems with analyzing and assessing hockey play from a possession - and particularly defensive - perspective is tracking which players actually make a significant impact within a given system. Generally this has been tackled by assessing a player's results within the context of their usage, then comparing a variety of statistical metrics to those of their "usage" peers. The best tools available at this point are player usage charts (Vollman), which are now available in a few locations. Metrics have also been devised that consider expected goals (Parkatti) and expected shooting percentage (Pfeffer), and win contributions - i.e. Total Hockey Rating aka THoR (Schuckers and Curro).

The problem one typically finds with trying to analyze players in "context", is that eyeballing context isn't amazingly easy. We all know what tough minutes are generally speaking, i.e. facing top opposition; playing big minutes; starting in your own zone frequently; playing with weaker line-mates, etc. Unfortunately there are implicit assumptions and unfounded impressions floating around that very few people seem to have spent much energy on assessing. Work must be done to determine what combination of various factors have meaningful impacts, thus providing us with a context for interpreting each player's results.

The Log Off Podcast: "In a lot of ways he's like Corey Perry, except without being nearly as good"

In this week's edition of the podcast we take a look at the awfully sparse list of free agents still there for the taking on the open market. In doing so Derek manages to compliment TJ Galiardi in a roundabout, backhanded manner, and we contemplate what exactly has happened to Devin Setoguchi in recent years. There was even, as promised, a discussion about the St.Louis Blues signing Chris Butler mixed in there somewhere. 

Regardless of how anyone feels about the quality or entertainment value of this podcast, no one can dare say that we aren't asking all of the important, hard hitting questions here.

We then closed out the show by answering questions we received from you, our loyal listeners. Remember that in future weeks you can get involved yourself by including #AskMrFin in your Twitter reply. We always welcome input and participation, particularly during these dog days of Summer.

Will Kane and Toews' contracts change NHL pay scale?

The Chicago Blackhawks signed Jonathan Toews and Patrick Kane to identical eight-year, $84 million contracts last week. They are the face of the Blackhawks so it made sense to re-sign them, but with a combined $21 million cap hit the new deals will limit the Hawks ability to add proven depth to their roster.

Of course the Hawks needed to keep these players, but even if the salary cap shoots up to $75 million in 2015/2016 Kane and Toews will eat up 28% of the total space. With that much of the cap eaten up by two players it makes it extremely difficult to add quality depth players, which is a necessity if you want to win the Cup.

The Log Off Podcast: "I really have nothing else to say about this signing"

Big thank you to @HockeyByDesign for the snazzy new cover.

Things have definitely settled down in the hockey world since our last podcast, with a large majority of the notable free agent signings having long since been settled. That left us with a riveting medley of subtopics to dissect this week, ranging from the earth-shattering Dany Heatley-to-Anaheim news, to an extended discussion about how many fighting majors the San Jose Sharks will incur next season. 

It's worth noting that these podcasts have become increasingly fun (for me, and I hope you, the listener) as we witness my co-host Mr.Fin get more and more comfortable in his now-permanent emotional fetal position with each passing week. 

As the show went on we also got around to talking about the likelihood of Evander Kane being traded, the new threshold set for paying superstars by the Toews and Kane contracts, and whether we would've personally given someone with as little NHL experience as Cory Schneider the contract that the New Jersey Devils did. All of that good stuff is just past the jump.
