Thanks for the article... I'll read it later, but I declare my a-priori skepticism.
I mean maybe over the long haul, for most players who are used in a variety of situations, it is probably true that zone starts don't matter.
But to your earlier point, if you are talking low n-size, single events are going to wildly skew your x-STATS and your real-STATS. You of course agree with that.
So then it stands to reason that if you have a role player (like a Desharnais as perhaps a better example), who is being PREFERRED by the coach in situations where no offense is expected, no offense is likely, and the key responsibility is to contain, get the puck out and get a shift change...
... well then all of those single events the skew meaning in the low n-size (situation based) scenario above, are just going to accrue disproportionately (relative to the population) as the n-size increases... No?
Desharnais, to come back to that example typically had 8% O-zone starts and 16% D-zone starts as an Oiler... sure the rest of the starts are on the fly or neutral, but when we talk about a GF% of 45:55 being "bad" and 60:40 being "elite", those disproportionate zone starts certainly have potential to skew it a bit... and when you start to talk about xSTATS, I expect they would skew even more (this based on my general bias that they don't yet do a great job of discerning true chance quality)... I mean, even with weighting, any shot against hurts your xSTATS and if your job is to "get it out and get off" twice as often as it is to pin the opponent in the o-zone, your stats will suffer.
If a typical NHL shift were long enough to ensure that each shift has some balance of O-zone vs D-zone, I'd be inclined to agree with you... but that's not always true and certainly isn't true for situational utilization.
Appreciate your post. I think what I struggled with is not the value of additional data and its help to give greater insight into team and individual performance, it is valuable in the right hands. More so I have trouble with how some people interpret the information to drive conclusions that I think are incomplete or inaccurate.
Long post, but last year I questioned an advance stats based case was made that Borgen was a much better defenseman than Larsson. There was a clear personal bias involved with the players involved (diminishing Larsson). This didn't smell right to my eye test (mixed metaphor aside haha) and I thought it would be helpful to do a deep dive on their ice-time, situational play, and ultimately largely inconsequential salary difference.
I have confidence when a math expert like
@Fourier uses information but feel conclusions are often made by some using incomplete, limited data. The challenge is to discern what is the fulsome 'truth'. In Larsson's case, I think there's an example where a quality goal suppression d-man gets nicked by some x-stats that bias toward offensive measures.
Looking robustly at alot of information I don't think the advance stat x-results based interpretation held up to the reality of these two players deployment and situational usage.
