Offensive Players Negatively Impact Save Percentage

January 29, 2017

It is all-star weekend and this past week Sportsnet.ca made their picks for “Analytics All-Star Team”. Their eastern conference picks are here and you can find their Western Conference picks here. Their criteria for picking the rosters was simple. They wanted to pick the most fun team to watch and that meant all-out offense. With that in mind, we thought we’d try selecting teams using a statistical basis, shooting for the…

Boosting save percentage…

Last night on twitter I posted some GF%RelTM statistics which resulted in a number of comments but notably some from Stephen Burtch about how players cannot be blamed for GF% and is nothing more than a fancy +/- stat and how players can’t be blamed or given credit for things such as save percentage. @hockeyanalysis @mlse Polak .910 on-ice sv% at 5v5 close past 4 years. Robidas .905 on-ice sv%….

Rush Shot Save Percentage

I have written a couple of posts (here and here) on rush shots as it relates to shooting percentages and I investigate this further at a later date. First though, I wanted to take a look at save percentages on rush and non-rush shots. Let’s start by looking at teach teams 5v5 road save percentages for the past 7 seasons combined. A few observations: Whoa Tampa! That’s a dreadful save percentage…

Maple Leaf defensemen and their effect on save percentage

The other day I looked at the effect that Mike Weaver and Bryce Salvador had on their teams save percentage (if you haven’t read it, definitely go give it a read) when they were on the ice versus when they weren’t on the ice. Today I am going to take a look at the Maple Leaf defensemen to see if there are any interesting trends to spot. We’ll start with the new…

Mike Weaver’s impact on save% (and Bryce Salvador’s too)

The other day I commented on twitter that I would be happy if the Leafs signed defenseman Mike Weaver because I think he is a defensive defenseman that I think the Leafs could really use. I have thought of Mike Weaver as a premier defensive defenseman for quite some time now. I always seem to get a little flak over it but that’s fine, I can handle it. For example,…

Bryce Salvador and looking beyond corsi

The rumour is out there that Sunny Mehta has been hired as Director of Hockey Analytics of the New Jersey Devils (if true, a big congrats to Sunny). This sparked some twitter discussion about the Devils and analytics and Devils defensemen including Bryce Salvador. @hockeyanalysis @ToddCordell I don’t know a ton about him apart from that he was the whipping boy of smart/analytically inclined NJ fans. — Fear The Fin…

The declining value of fenwick/corsi with increased sample size

The last several days I have been playing around a fair bit with team data and analyzing various metrics for their usefulness in predicting future outcomes and I have come across some interesting observations. Specifically, with more years of data, fenwick becomes significantly less important/valuable while goals and the percentages become more important/valuable. Let me explain. Let’s first look at the year over year correlations in the various stats themselves….

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…

Zone Start effects on Goalie Save Percentage

While doing my earlier post on Luongo’s value I noticed that Luongo’s 5v5close zone start adjusted save percentage relative to the rest of the league is much more mediocre than his 5v5 save percentage.  I decide to look into this further and realized that this is in large part due to zone start effects, and not score effects.  This got me to look into zone start effects on a goalies save…

Thoughts on PDO and Luck

One of my beefs in the analysis and evaluation of hockey players is the notion that PDO (on-ice shooting percentage plus on-ice save percentage) can be used as a proxy for luck.  A perfect example of how PDO is used as a proxy for luck is this article by Neil Greenberg about the Washington Capitals. For example, when Alex Ovechkin has been on the ice during even strength this season,…
