The level of disdain is pretty easy to figure out, I'd say. Too many people treat things like corsi as the One True Stat that is infallable. They seem to forget that the stat isn't even a measure of possession or quality. It is a measure of workload for a goaltender.
But we extrapolate and we assume, and while we do find a generally stronger correlation to success than many other statistics, that correlation is not nearly as strong as hardcore advanced stat types want to believe. And, as I see on Twitter all the damn time, these types immediately martyr themselves when people express skepticism.
I also find that, typically, a high corsi team doing well or a low corsi team doing poorly is treated as a validation, while a high corsi team doing poorly and vice versa is excused away. Most often as "luck". That creates a scenario where it becomes obvious people are only using the stat to confirm pre-existing conclusions. And that damages the overall credibility.
