I like statistical approaches to hockey analysis but I can say unequivocally that the level of "peer review" and expert discourse about hockey-related models doesn't come close to most scientific fields. There isn't nearly as much transparent scrutiny of data quality and methods as you would see in most research fields. Moreover, many of the hockey stats folks make a living from their own proprietary models. I don't object to that at all, but it does tend to create a level of defensiveness and brittleness that can stifle healthy discourse. Add in that some rely on revenue from the sports gambling enterprise, and things get even murkier.
That said, I find most of the public modelers and data scientists in hockey to be very sharp and engaging. They can be overly dismissive, but that's a feature of social media, generally. I would note that there is also a large contingent of hard core "anti-stats" folks that add to the rancour by dismissing useful statistical insights out of hand.
Balance is hard to find, but overall I think that the introduction of statistical insights has been a great addition for the engaged fan.
