On-ice shooting percentage is sustainable…

April 19, 2012 in fenwick, predictability, shooting percentage, sustainability, true talent by davidjohnson

Prior to the season Gabe Desjardins and I had a conversation over at MC79hockey.com where I predicted several players would combine for a 5v5 on-ice shooting percentage above 10.0% while league average is just shy of 8.0%.  I documented this in a post prior to the season.  In short, I predicted the following: Crosby, Gaborik, Ryan, [...]

Lupul’s always been this good.

March 2, 2012 in Joffrey Lupul by davidjohnson

A lot has been made about Joffrey Lupul’s “career year” this year and some Leaf fans are even suggesting that now is the time to trade him while his value is at an all-time high.  While it is true that he is on pace for career high in goals and points I would like to [...]

What is Rick Nash?

February 14, 2012 in Brassard, Huselius, Lupul, player analysis, Rick Nash, Voracek by davidjohnson

So word has come out over the last day that Rick Nash is, at least on some level, available in a trade from the Blue Jackets.  So, the question is, who is Rick Nash and would you want him on your team? Nash has been a Blue Jacket from the day he was drafted first [...]

Defenders effect on Save %

February 9, 2012 in defenders, on-ice shooting percentage by davidjohnson

It has been shown on numerous occasions that players can influence their own teams on-ice shooting percentage be that through their talents or their style of play.  An example is the PDO vs Luck article I posted the other day.  In that article there is a table that clearly shows that shooting percentage varies across players and [...]

Thoughts on PDO and Luck

February 5, 2012 in PDO, save percentage, shooting percentage, using statistics properly by davidjohnson

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. [...]

Zone Start Effects on Stats

February 1, 2012 in adjustment, zone starts by davidjohnson

Over the past week or so I have talked about a simple and straight forward method for taking into account variations in zone starts.  The method is to simply ignore the 10 seconds following an offensive or defensive face off.  By adjusting for zone starts in this manner we can see a fairly significant impact [...]

Evaluating the Leafs Defensemen

January 26, 2012 in defensemen, Franson, Gardiner, Komisarek, Liles, Phaneuf by davidjohnson

With the re-signing of John-Michael Liles the Leafs now have an abundance of defensemen signed under control for a number of years, many with big dollar contracts too.  We all have our varying opinions on the relative values of each of these defensemen but I thought it would be an appropriate time to take a [...]

Importance of Quality of Competition/Teammates

January 25, 2012 in quality of competition, quality of teammates by davidjohnson

Whenever I get into a statistical debate over which player might be better than another the inevitable argument that comes up is “yeah, but player A plays against tougher competition and gets tougher assignments” which is a valid argument to make.  But how valid?  The other day I looked at a simple, straight forward method [...]

Adjusting for Zone Starts

January 23, 2012 in zone start adjustment, zone starts by davidjohnson

One of the biggest omissions in my player rankings is making adjustments for zone start differences.  We know that Manny Malhotra has a significant bias towards starting his shifts in the defensive zone and that his teammates Daniel and Henrik Sedin have a significant bias towards starting their shifts in the offensive zone.  The result is Malhotra [...]

Tim Thomas vs Tuukka Rask

January 12, 2012 in tim thomas, Tuukka Rask by davidjohnson

There is a post over at Backhand Shelf today that lists 10 backup goalies that have out performed their #1 counterparts.  It is an interesting read but it may be a perfect example of how simple statistics don’t tell the whole story. The first pair of goalies on the list are the Bruins Tukka Rask [...]
