Team Level Shooting and Save Percentage Matters

For those familiar with my history, I have been a big proponent that there is more to the game of hockey than corsi and that players can certainly drive on-ice shooting percentage. I have not done much work at the team level, but now that I have team stats up at I figured I’d take a look. Since shooting percentages can vary significantly over small sample sizes, my goal…

Read More >> updated with 2013 and team stats

I have updated to include 2012-13 data (even though it is way too early to draw any real conclusions from it) and also to add several new features: Added team data. Added QoT and QoC (offense, defense and overall) stats based on Hockey Analysis HARO (offense), HARD (defense) and HART (overall) ratings. These QoT and QoC are essentially the average teammate or opponent HARO, HARD or HART rating. Changed…

Ilya Kovalchuk’s power play ice time

The last few days I have been looking at the percentage of a teams ice time for a given situation that a particular player is on the ice for.  So for instance, what percentage of the Leafs 5v5 even strength ice time was Joffrey Lupul on the ice in games in which Joffrey Lupul played. When I write a new program to calculate these numbers I need to to some…

Player TOI Usage Charts with Performance Metrics

The other day I introduced a new way of visualizing player time on ice and usage and today I am taking that one step further by superimposing a players performance on those charts. So, with the TOI usage charts I presented the other day you can see how frequently a player was on the ice in any particular situation relative to how frequently the team plays during that situation.  So,…

Player TOI usage charts

One of the challenges in hockey analytics, or any type of data analysis, is how to best visualize data in a way that is exceptionally informative and yet really simple to understand. I have been working on a few things can came up with something that I think might be a useful tool to understand how a player gets utilized by his coach. Let’s start with some background. We can…

Lupul, one of leagues best scorers, re-signs with Leafs

The Leafs announced today that they have re-signed Joffrey Lupul to a 5 year contract extension at an average salary and cap hit of $5.25M/yr.  Some Leaf fans are a little dismayed at both the value and the term of the deal as many people seem to view Lupul as a second line winger with a defensive liability that should have been traded, not re-signed.  I won’t deny that Lupul…

An even strength offensive comparison of Kadri, Bozak, Connolly and Grabovski

Earlier today I wrote a post about Tim Connolly and his offensive production at even strength. Shortly after posting that I thought a similar article comparing the performances of Bozak, Kadri and Conolly would be an interesting piece since they are sort of competing for roster spots (more so Kadri and Connolly than Bozak though). Of course, in the mean time Connolly has been put on waivers so to some extent he…

Tim Connolly and individual PK%

Yesterday evening James Mirtle from the Globe and Mail posted an article on The Curious case of Tim Connolly and the Leafs.  It’s worth a read so go read it but the premise of the article is how the narrative around Tim Connolly in training camp is he had a poor year last year and he needs to perform better this year.  Makes sense from most peoples view points but…

State of the Maple Leafs post Brian Burke

The news that shocked the hockey world yesterday had nothing to do with the CBA or Bettman or Fehr but rather that the Maple Leafs ownership group decided to make a strangely timed move to remove Brian Burke from his President and General Manager position of the Maple Leafs.  I think it is only fair to take a look back at the Burke years and evaluate where the Leafs are…
