TSN Analytics Team, Even Strength Play and Marc-Edouard Vlasic

Earlier this week TSN announced the creation of an Analytics team consisting of long-time TSN contributor Scott Cullen along with new TSN additions of Globe and Mail’s James Mirtle and hockey blogger Travis Yost. I am all for main stream media jumping on board with hockey analytics but once you go from independent hockey blogger to a significant contributor to TSN I think it opens the door to higher expectations and higher standards.  Scott Cullen has a long track record with TSN and I am confident James Mirtle will bring some intelligent insight as we are all familar with and respect his

Estimating actual randomness in goal data

If you have been following the discussion between Eric T and I you will know that there has been a rigorous discussion/debate over where hockey analytics is at, where it is going, the benefits of applying “regression to the mean” to shooting percentages when evaluating players. For those who haven’t and want to read the whole debate you can start here, then read this, followed by this and then this. The original reason for my first post on the subject is that I rejected Eric T’s notion that we should “steer” people researching hockey analytics towards “modern hockey thought” in

Visual WOWY representation of Jay McClement’s poor possession play

A few people didn’t like that I suggested that Jay McClement was a bad player in yesterday’s Mikhail Grabovski post so I thought I would provide a visual representation of McClement’s  mediocrity in the form of 5v5 Zone Start adjusted CF% WOWY charts for each of the past 6 seasons (this season included). Let’s start with this current season even though the sample size is relatively small and so the number of line mates with a reasonable number of minutes with McClement is relatively small. In this chart, it is better for McClement to have the bubbles below and to the

A Corsi vs Goal based evaluation of Francois Beauchemin

Over the past few years I have had a few discussions with other Leaf fans about the relative merits of Francois Beauchemin. Many Leaf fans argue that he was a good 2-way defenseman who can play tough minutes and is the kind of defenseman the Leafs are still in need of. I on the other hand have never had quite as optimistic view of Beauchemin and I don’t think he would make this team any better. On some level I think a part of the difference in opinion is that many look at his corsi numbers which aren’t too bad

IPP WOWY Analysis of Crosby/Malkin and Thornton/Marleau

The other week I wrote about breaking down IPP (Individual Point Percentage, which is individual points divided by number of goals scored while the player was on the ice) into IGP (Individual Goal Percentage) and IFAP (Individual First Assist Percentage).  It seems IGP does a decent job of identifying the pure goal scorers and IFAP does a decent job of identifying the pure play makers.  I have always been interested in team/line makeup and how to maximize a lines performance so I decide to take a look at WOWY IPP comparisons for two pairs of extremely talented players who have

Quality of Competition in 5v5 Close Situations

I have been wondering about the benefits of using 5v5 close data instead of 5v5 when we do player analysis and player comparisons.  The rationale for comparing players in 5v5close situations is that we are comparing players under similar situations.  When teams have a comfortable lead they go into a defensive shell resulting in fewer shots for but with a higher shooting percentage and more shots against, but a lower shooting percentage.  The opposite of course is true when a team is trailing.  But what I have been thinking about recently is whether there is a quality of competition impact

Henrik Zetterberg Player Analysis

I have written a few controversial pieces here at HockeyAnalysis.com (for example, my post on Luke Schenn back when Leaf fans thought Schenn was the best thing since sliced bread) and I suspect this might generate some controversy as well because of the conclusions made about Zetterberg’s weak defensive ability.  I also want to do this post to show how I believe we should be doing player evaluation because I believe that most people evaluate players in a poor way. The first thing I believe is that we must evaluate players based on goals and not corsi/fenwick/shots because there is

State of the Leafs – Forwards

With the Maple Leafs season having ended early once again a it is time to take an honest and unbiased look at what the team has and what the team needs to get to improve.  This will be a multi-post endeavour that will start with this post which will be a statistical evaluation of the Leafs forwards.  Included in each players evaluation is a table of their 5v5 zone start adjusted HARO+, HARD+ and HART+ ratings over the past 5 seasons (where available) as well as 3 and 5 year ratings.  These ratings provide an unbiased zone start, quality of teammate

Showing Shooting Percentage Matters (Yet Again)

I hate to keep beating the “Shooting Percentage Matters” drum but it really dumbfounds me why so many people choose to ignore it, or believe it is only a small part of the game and not worth considering and instead focus their attention on corsi/fenwick, and corsi/fenwick derived stats as their primary evaluation too. It dumbfounds me that people don’t think players have an ability to control shooting percentage yet we all seem to agree that shooting percentage is affected by game score.  Rob Vollman wrote the following in a comment thread at arctic ice hockey. <blockqote>The score can affect

Some Thoughts on Shot Quality

There has been a fair bit of discussion going on regarding shot quality the past few weeks among the hockey stats nuts.  It started with this article about defense independent goalie rating (DIGR) in the wall street journal and several others have chimed in on the discussion so it is my turn. Gabe Desjardins has a post today talking about his hatred of shot quality and how it really isn’t a significant factor and is dominated by luck and randomness.  Now, generally speaking when others use the shot quality they are mostly talking about thinks like shot distance/location, shot type, whether
