NHL Forwards vs. Defensemen Height & Weight, 1917-18 to 2014-15

Building on my post from last week on overall skater height going back to 1917-18, I wanted to dig a little further into the the complexity of the data to see if there were any interesting takeaways. This included breaking the data into forward and defense data, to see if there was every any substantial increase in defenseman size or any other allusions to an attitude change in terms of size trends and preferences. While there are some slight differences, most interesting to me was, for as many changes as the NHL has undergone, there seems to be a uniform attitude about size when looking at forwards and defensemen.

The Goal Impact of Even Strength Faceoffs for NHL’s top 100 Faceoff Centres

A debate was ongoing on twitter over faceoffs and their value. The debate lead to most of this data being scraped anyways, so I thought I would display everything for your viewing pleasure.

The truth is, faceoffs tend to be highly overrated. They matter, but they do not matter much more than any other of the many puck battles that occur throughout the game. When you really break it down, faceoffs are really just a set play puck battle after all.

Let’s take a look.

We are all human

Hey everyone.

A bit of a change of pace for Hockey-Graphs, here is a bit of an informal blog post. There are two separate things I want to address.

First thing:

I made a mistake.

Long ago on an article about Corsi and context, I made an error with moving the data from one spreadsheet into another. Everything in the specific article was actually correct. However, I had linked to a summarized data table on Google docs though that had some erroneous data on it.

The Google doc had summarized the average goal differentials for sets of players given their position in the depth charts and their Corsi%. What had happened is I accidentally copied 2nd line and 3rd line forwards in both their appropriate place and where 2nd and 3rd pair defenders should go. The online document has since been corrected and can be viewed here.

I made another mistake though in building an article off of that Google document. This article used the previous data in creating a quick model to estimate the goal impact difference between two players with differing Corsi percentages. The image has since been corrected.

I want to always be clear of my methods and my intentions, so this is why I wanted to post this to you.

Second thing:

Far smaller detail, the Hockey-Graphs podcast will be postponed until probably Friday. Rhys and I were not able to find a time convenient to both of us in order to record a session until then.

Sorry.
Until next time and thank you for reading and supporting our work.

NHL Player Size From 1917-18 to 2014-15: A Brief Look

As any person interested in hockey stats should do, I’ve been gradually building my own personal database of player information that I can use when Y3K robs my future post-human self of cloud data for 3 seconds. To that end, player size wasn’t a huge priority but I knew eventually I’d want to have it, if only to think about how normal-sized I’d be in the 1920s NHL. In the process of bringing in all that data, I decided to do a little demographic work on player height and weight. We all know the players are bigger now than they were before, but by how much? And is there greater variance in size now or in the past?

Regular season hit differentials and the playoff success

Last time we looked at the relationship between hit and goal differentials. We showed that the outhit team tends to also be the outscoring team.

On Twitter, the subject of playoffs naturally came up. Do physical teams get an edge in the post-season?

I’ve been already pulling some data on the playoffs and doing some studies. I thought this would be a good opportunity to show a few of my early findings.

The Usefulness (or lack thereof) of Hit Totals

From Wikimedia Commons

The hit statistic rivals the faceoff in praise by some more traditional hockey analysts. Both statistics are also similarly over valued in terms of their impact to the game. There has been work previously shown that the hitting statistic actually has a negative relationship with winning.

I wanted to look into this just a  little bit further. I went to War-On-Ice and downloaded data for every NHL game since October 2007. I then cleaned the data and took a little look. Continue reading
