Back in July of 2009, Gabriel Desjardins at PuckProspectus tried to identify whether or not winning a hockey fight could be the impetus behind a boost in team scoring. He found virtually nothing.

More than four years later, I've found a much more significant set of data. The numbers may surprise you.

Western Conference: Line/Tier v. Team Production

One of the elements of hockey analytics that I think is understudied is the midpoint between individual and team-level data. Line combinations change an awful lot over the course of an eighty-two game season. Even in forty-eight, we see coaches -- be it injury-related, performance-related, whatever -- continually juggle trios of forwards on a game-by-game deployment. For this reason, I think a lot of people unfortunately shy away from it.

In my previous work I was working on predictions in hockey, at the micro level of a single game, to determine who will win and who will lose. I was using Machine Learning techniques (or algorithmic modeling) and one thing I've noticed from my work, and from reading papers on other peoples material, is that for every sport there seems to be a prediction limit (that is different for every sport). This is what I want to explore; how much of the results that we see are based on luck, and is there a theoretical prediction limit in the NHL? 

In this post I will be focusing on the first question, what part of the standings is made up by luck?

Reviewing the NHL Entry Draft - 2000 to 2008

July 31 2013 10:44PM

This is the third in a series of articles looking at the history of the NHL Entry Draft from 1979 to 2008. I have tabulated every pick made by every team during that time, selecting out the players who managed 200+ NHL games as draft successes. The initial look is a simple study wherein I credit a team with finding an NHL player, regardless of their draft position or impact on the NHL. The notable weaknesses of this approach are that it evens the playing field between the 3rd line journeyman winger and the franchise defenseman.
