Going On Hiatus…

I just finished an 8-part series on roles and statistics with a specific intent of showing that certain types of players or playing styles have impacts on save percentage. It was received well by some, not so well by others. Clearly there are detractors however this is a case of been there, done that for me. I went through the same debates 5-6 years ago with on-ice shooting percentage. I am confident…

Roles and Stats Part VII: Can roles predict future shooting and save percentage?

In the first six parts of this series I have looked at the relationship between roles and player statistics and, particularly for forwards, there is a clear relationship between how a player is used and their resulting statistics. Now this isn’t an absolute relationship as we saw with Brandon Sutter in part six of this series but it does exist. Thus far I have only presented an “in-sample” relationship (relationship…

Roles and Stats Part VI: Who’s Who?

I recommend you read some or all of the previous posts before reading this one starting with my first post where I provide a background and the overall methodology of this research project.

Roles and Stats Part V: Roles and Defensive Stats – Defensemen

This is part five of my series on roles and stats. In part four of the series I looked at how roles relate to the offensive statistics of defensemen and found that there was a relationship however it was not nearly as strong as for forwards (as one would expect). Today I will look at roles of defensemen and defensive statistics which one would think ought to show a stronger relationship….

The history section is optional but I recommend reading the methods portion as it describes the statistics and methods used which will not be discussed in great detail here. The second post in the series looked at the relationship between roles…

Roles and Stats Part I: Background and Methodology

This is the first of what will be a series of posts on the impact of roles on stats with a particular interest in the impact of roles on shooting and save percentages. Background My involvement in hockey analytics has been somewhat outside of the main stream. I am a firm believer in shot quality and the ability of players to influence on-ice shooting and save percentages while hockey analytics has…

Warren Buffett on Brandon Sutter

Yesterday I wrote about Brandon Sutter and his seemingly very good defensive ability in response to @DTMAboutHeart‘s comment that he was a below replacement level defensive player. The counter argument that @DTMAboutHeart (and others) put put is that Save % is all random and it infects goals against data with mass randomness that will inherently lead to outcomes like Sutter’s goals against stats that have no basis in talent. Exhibit A…
