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 stats.hockeyanalysis.com I figured I’d take a look. Since shooting percentages can vary significantly over small sample sizes, my goal was to use the largest sample size possible.  As such, I used 5 years of team data (2007-08 through 2011-12) and looked at each teams shooting and save percentages over

Stats.hockeyanalysis.com updated with 2013 and team stats

I have updated stats.hockeyanalysis.com 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 WOWY pages so that both goal and corsi data are on the same page for easy comparison. Included individual stats in the WOWY pages so we can see how many

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 testing to make sure the results are correct.  The first test is always the standard sniff test.  When the program runs I look at the output and ask myself “does

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, a player might be on the ice for 30% of the teams 5v5 game tied minutes.  The next logical step is to take a look at his production during those

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 get an idea of how a player is utilized by looking at when the player gets used and how frequently he gets used.  Offensive players get more ice time on

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 is a defensive liability (though wingers generally have less impact on defense than centers or defensemen), but I will dispute the claim that he is a second line winger. Last

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 isn’t relevant anymore but I am including him for interest sake. Here is a look at their individual offensive performances for the last 2 seasons for Bozak and Kadri and

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 Connolly tries to present a different perspective. Connolly can be prickly to deal with and wasn’t particularly interested in talking about last season, but when pressed, you could tell he

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 after his 4 years at the helm.  Let’s look at the Leafs position by position starting with the good and heading downhill from there. Defense Burke made some mistakes on
