I think advanced stats has a place during the course of a regular played game in which players and teams aren't conscious of it. It really just tells you who's carrying the play and creating more chances, which is usually the better team.
I think the mistake is when you try to play to it as a way of making your team better. Instead of passing to someone in a higher percentage scoring position, you take a shot, instead of driving to the net, you take a shot... sure, you'll increase your Corsi and Fenwick but you're likely turning the puck over more and generating less quality chances. I think you'd likely make your team worse if you were consciously trying to play for positive Corsi and Fenwick.
So I guess I’m saying there are a natural Corsi and a contrived Corsi. I think if teams are moving toward the idea that taking more shots will automatically make them better(contrived), Corsi will become less an indicator of how good or bad a team is.
