Of course it matters. And to say it is not common is a bit of an understatement. There have been 200 18 year olds that tallied points in the NHL at the age of 18. Your comparison just put him into the top 15 of all time. That does not speak volumes of the likelihood that such things occur. Heck, Rick Nash scored 39. Do you think that Kakko is already every bit the player that Nash was? Or Patrice Bergeron?
This is exactly what I am talking about as having completely unrealistic expectations and then deeming the season a "disappointment" when it is not achieved.
First of all, what do Finnish NHL pros have anything to do with it? Are they better at predicting play than Russian ones or Swedish ones? Second of all, yes, if you look at it from a historical perspective, it is very much out of whack.
1. ZBad was a borderline elite center prior to the season starting.
2. The Rangers just brought in an elite top line wing.
3. There is ZERO chance that said elite top line wing gets demoted to the second line.
