I just don't think there's a place for analytics in hockey right now, maybe ever. This sport's so f***ing chaotic and impossible to predict as opposed to a relatively neat and tidy sport like baseball, which is prime for analytics. Hockey's got about a billion moving parts and variables at play, all changing throughout the course of a shift, let alone a game or season. Seems like a fruitless endeavor to me, but whatev.
It's very easy to just kinda laugh and roll your eyes whenever something suggests Petts is in the upper elite for anything offensively related, or when some analytic put McCann in the same convo as guys like McDavid, Draisaitl or Barkov a few years ago when he was still with the Pens.
There definitely is a place for analytics in hockey right now, and, in fact, it has already changed the game considerably, despite still being in its infancy. (The type of players valued now, how the game is played; all of this has changed considerably in the last 10-15 years, which is still well after the rule changes coming out of the 2005 lockout).
That said, I think hockey media still doesn't really understand it very well, and therefore doesn't do a good job of explaining it. (Explaining what Corsi is, for example, isn't very useful if you don't understand why it's a useful stat to track in the first place). The actual analysts themselves are so far deep into it they just jump to "the r-values tell us..." without actually tying that in to play on the ice, and why that matters.
All of which results in the average fan only getting "this stat means this player is good/bad", which is often a rather incorrect view of those stats in the first place.
This is not to say that I blame the average fan, either, because the explanations are simply not out there. Again, all the articles I've ever found that "explain analytics" either just give an incredibly basic explanation of the terms without explaining why they matter, or else they turn into arcane statistics terminology without relating it back to how the game is actually played on the ice.
Let's take one basic example: Corsi.
At this point, most people know that "Corsi" is just a term for "shot attempt": it's all the shots, blocked shots, and missed shots taken. But why does it matter? Well, the stats people discovered that it highly correlated with winning. And here's where things start breaking down. See, there's a common saying that very much applies here: "Correlation does not equal Causation." Correlation just means that you see two things often happen together. But that doesn't actually tell you that one caused the other. With Corsi, it's important to understand this basic fact:
Corsi does not cause a team to win.
Corsi
correlates with winning teams. That because winning teams tends to create a lot of shot attempts. And
that is because winning teams tend to possess the puck more, which leads to them getting more opportunities for shot attempts. But even getting more shot attempts alone isn't enough to cause winning - that's because skill is a factor. If all your shots get blocked, it won't matter if you're getting more attempts than your opponent, if your opponent is able to get shots on net and you aren't.
And that's just one example.
This is also why I don't like attempts to create a "WAR" stat for hockey, or the compression of various stats into some all-encompassing rating of a player. Hockey is chaotic enough that individual skills still matter, and since any given player has to play both offense and defense, any skill they have is going to affect
both, and it's important to understand
how and not just look at any single individual stat.
