Right. Maybe this is where observation/watching the games can play a part, as long as it's combined with an understanding of the talent distribution for team on-ice shooting %.

I agree. I just have the feeling that some analysts today would be downgrading 19-year old Mario Lemieux or Wayne Gretzky based on their "unsustainably high percentages", and those guys went on to create a ton of value out of those percentages. It looks like Sidney Crosby creates a lot of value from the percentages as well. Maybe Ryan Nugent-Hopkins will in future. We should be open to recognizing value no matter how it is created.
