Welcome to the third episode of the Hockey Graphs podcast, where Rhys Jessop (of Canucks Army and That’s Offside) and Garret Hohl continue talking about hockey while learning how to podcast. Join us as we lament the death of Corsi. We also talk about Mike Richards hitting the waiver wire, All-Star game, and (as always) some prospects and draft theory. Continue reading
No, not roster. Lines. This won’t be a discussion of hits and misses for the rosters.
While usually Hockey-Graphs tends to stay in the more serious and analytical side of sports statistical writing, I thought “why not have a little fun” since that’s what the All-Star break is supposedly about.
How would one shape the line ups for tonight if the best (minus some missed calls and injured) in the business were designed by statistical analysis (with a pinch of old-school eye-test)? Continue reading
Within the continuing discussions over the value of possession metrics, and the veracity of shot quality or shooting talent measures, there’s a point that seems to have slipped through the cracks. While there’s a spectrum of attitudes about possession and shot quality/talent, neither entirely refutes the importance of the other – and with that thinking, it’s worth considering how much you can sacrifice in one and still maintain success by the other. Put more simply, how little can a team possess the puck and still expect to shoot their way to success?
Welcome to the second episode of the Hockey Graphs podcast, where Rhys Jessop (of Canucks Army and That’s Offside) and Garret Hohl continue talking about hockey while learning how to podcast. Join us as we discuss the CSS rankings, Vancouver Canucks, Winnipeg Jets, Toronto Maple Leafs, the NHL’s disciplinary practices, and the up coming All-Star game. Continue reading
Faceoffs have always been an interesting area of research. There have always been individuals in the media and public who extol faceoffs importance; I have even heard quotes like: puck possession is so important and you cannot win the puck possession battle if you are starting without the puck.
Not too long ago Gabriel Desjardins showed that the impact of a faceoff is real (as one would expect) but likely over glorified by some. One example from his study showed shot rates after an offensive zone faceoff:
From these numbers Desjardin estimated an impact of +2.45 goals for every 100 non-neutral zone faceoff wins over 50%, and +3.66 for every 100 for special teams. A real impact, but not overly huge impact. Neutral zone faceoffs carried even less of an impact with +0.90 goals for every 100 faceoffs over 50%.
But what about faceoffs overall relationship with possession? Continue reading
Welcome to the inaugural episode of the Hockey Graphs podcast, where Rhys Jessop (of Canucks Army and That’s Offside) and Garret Hohl navigate the wonderful world of podcasting for the first time ever. Join us as we discuss Vancouver Canucks and Winnipeg Jets prospects, what the hell is up with the Anaheim Ducks, and, of course, a healthy dose of fancystats. Continue reading
Rand Carlyle was recently fired from the Toronto Maple Leafs. This brought joy to many online Leaf fans as many –legitimately– believed Carlyle to be a source of the Maple Leafs consistently being out shot, out possessed, and out chanced.
Of course, Carlyle was not the difference between the Leafs spontaneously becoming a contender in the east. There are issues with the Maple Leafs that will take some time for Brendan Shanahan and company to fix. Continue reading
League wide univariate analysis isn’t very sexy, which is why you rarely see it used in the hockey blogosphere. Still, the information is necessary in better understanding what we are describing and adding context. It is also useful for looking back at whenever a variable may not impact or work in a model as you initially hypothesize.
I gathered all player season data for each full (excluding lockout) season available in the “Behind the Net era”, filtering only forwards with 100 or more minutes. These seasons were combined into one massive sample of 2368 player seasons. Continue reading
