# Kings' assistant Bill Ranford cites Corsi to TSN's Ryan Rishaug

I thought this was real cool. At the start of the second period between the Los Angeles Kings and San Jose Sharks, Chris Cuthbert threw it down to reporter Ryan Rishaug for a quick hit where he actually gave some pretty good info as a result of a mid-game interview:

Chris, I spoke with Kings' assistant Bill Ranford at the break I asked 'which part of the stats page makes you the most upset?' He said 'their number of attempts and our lack thereof'. If you consider that San Jose had 15 shots on net, they missed the net eight times and had 14 blocked. That's 37 attempts on net. The Kings had just seven.

There you see the zone time, not even close. Los Angeles with half the offensive zone time that San Jose had. Ranford says 'we are losing every battle in our own end and we are not competing'.

I've screencapped the accompanying graphic, which is some real hipster stuff because you can't find "zone time" anywhere online. It has to be manually tracked. We use Corsi, basically shot attempt differential, as a proxy for zone time, but only because the zone time numbers aren't available. TSN did a great job at showcasing the Sharks' advantage in the first period.

Kudos to Rishaug and TSN there.

# Can we make predictions in hockey with Machine Learning? A simple experiment

## Introduction

You probably don't know me, my name is Josh Weissbock and I am a Masters student at the University of Ottawa up in Canada and I study Machine Learning.  Many of the other authors on the Nations Network, who use advanced stats, typically use statistical models to analyze hockey where as I use algorithmic models. What I can do is use Machine Learning techniques which is an application of these same statistical ideas.  Machine Learning is simply the ability for a computer to take a whole bunch of data, learn from it and be able to make decisions.

# Tomas Vokoun to start game five for Pittsburgh, and it’s absolutely the right decision

With Marc-Andre Fleury’s fourth consecutive playoff implosion, the Penguins have finally done the inevitable and decided to use a different goaltender in the post-season. With all due respect to his strong regular season play, the possibility of this was the biggest reason why signing Tomas Vokoun in the summer was a decision that had to be made.

# Top-30 Draft Prospect NHL Equivalencies

Before we begin breaking down individual scouting reports for the various first round hopefuls I decided to survey the entire field from a high level using NHL equivalencies (NHLE). For those unfamiliar, NHLE is a method that corrects for league quality relative to the NHL, allowing us to compare kids across various leagues.
