Pionk might be Exhibit A for the rift between the analytics community and the "traditionalists". I was part of the contingent of critics of the trade, based on public shot metrics models.
Here's a parody of the dialogue about Pionk that might illustrate why their is a rift...
Traditionalist: Pionk is a skilled young D who competes and moves the puck well. He'll be a good player:
Data aficionado: It doesn't really matter what scouts think about Pionk's skillset, his on-ice results are really bad so he's an ineffective player and a bad acquisition.
Traditionalist: Ha, you don't understand that Pionk had a tough role on a dysfunctional team, so you can't project his value based on his metrics with the Rangers.
Data analyst (rolls eyes): You evidently don't realize that the models adjust for context, so Pionk's performance is accurately reflected by his adjusted shot metrics.
Traditionalist: Even so, Pionk is still a young defenseman, and he is going to improve with experience because he's got good skills and works hard to improve.
Data analyst: The data show that on average defensemen peak at around Pionk's age, so the odds are against him improving at this stage of his career.
Traditionalist: Well, I trust my eyes more than the data and I think he'll be a good addition. Besides, Chevy and the scouts know more about hockey than you.
Data analyst: Well, you just don't understand the data concepts and are stuck in the past, just like Chevy, Maurice, etc.
A couple years later...
Traditionalist: See, I told you that Pionk is a good player and would thrive in a new environment.
Data analyst: ....
I'm thankful that we have some data scientists (like
@garret9 ) that are balanced and some "traditionalists" that are open to different perspectives on this board. But there is a lot of negative potshots taken in social media and in some of the HF Boards discussions that tend to polarize the issues, leading to closed minds on both sides. My guess is that a player like Scheifele hears that a player like Pionk or Wheeler or Connor is trash, based on data, and from his perspective that's "hogwash". He's probably looking at much different variables, and is understandably skeptical when the data come to very different conclusions. As illustrated above, his assessment of a player like Pionk was probably more accurate than the data-based assessment. Until there is a better understanding of context and chemistry, those discrepancies will continue to create misunderstandings.
Traditionalist:
