Relating to Hockey Blogs, bloggers and commenters, who are focused on the use of advanced statistics in their analysis of players, often disregarding the fact that hockey is a team sport and cannot always be explained through a reliance on advanced statistics that focus on individual performance.

A Circle Jerk For Geeks blog is when those who are focused on these statistics (aka, "stats heads") beef each other up and pat themselves on the back for being elite hockey fans because they "understand" advanced stats and use them as a crutch.
Examples of content on a Circle Jerk for Geeks:
