So much irrelevant information. The criterion for a particular 'draft choice' isn't affected by numbers proving or disproving the pick, in the years following the Draft. 'Projecting' the success of 17/18 yr. old players involves many aspects of non-hockey related conditions; that don't relate to 'raw' numbers in any way, whatsoever.
Hindsight is a useless tool at the draft table. In my opinion, a player's draft position is meaningless once they become part of an Organization.
The opportunity is there for any 'prospect' to forge a place within the depth chart of the roster/organization. The reasoning on Draft Day doesn't change because of a perceived alternate developmental curve (positive or negative).
Unfortunately, the vast majority of the 200+ drafted players each year, will play professionally (or not at all) in leagues other than the NHL. That's the reality the players understand; and therefore, 'skill' is but one aspect of what it will take to reach the 'dream'.
If you want to keep your head in the sand and be a cheer leader then sure. Everything is irrelevant. Might as well close up shop and just wait till they make the NHL. What they did yesterday doesn't matter, that's heindsight now.
I for one am interested in advancing the approaches and understanding of identifying which prospects develop a which don't, and improving the methodology used by most teams.
This includes treating draft picks as the valued business resource they are, understanding the opportunity costs of who you select, and maximizing your returns.
It's easy to say "well there's so much that's untrackable and unrelated that we'd never get an accurate picture so why bother using numbers", but if even the very limited amount of numbers outperforms the current method, then clearly they are worth incorporating to some extent.
This relates to the Stanley discussion for a number of reasons:
Expectation.
Many dislike the Stanley pick because at the time it seemed like a bad use of currency. The numbers supported this. Those who liked the pick say "they know something we don't, it's a good pick"
His development was then discussed in terms of point production because we don't really bhave a good way of saying what development is (he "looks better" can't really be proven/tested it just becomes an unfounded opinion pissing match). Using our system we try and get a better handle on that. He increased point production, but that's expected, has he increased his production enough to show an increased likelihood in future success (ie: development)? Yes.
This may be the caveat: I am defining "development" as reducing the number of comparable players who failed and increasing the number of successful players as development.
Ok, next question, has it increased enough to remover the concerns that people had on draft day?
Answer: yes and no. The point is getting a handle on what his development actually has been. How much has improved not vs where he was but vs where he's expected to be. If this pace continues, he has improved his development to the point where we would say , "ok maybe they DID know something we didn't", because he's now at the appropriate threshold of value for a player +2 years out of the draft and taken 20th overall, where's he was quite negative value for a former 20th overall pick in Dy and Dy +1. He has risen his stock. He's improved his chances of success. On the other hand had he been a player who was 40% success rate all three years we would say "he's developed enough to tread water, he is as we would have expected", his stock has not risen but not fallen. I say "no" to this question as well because while it appears they may have "known something new didn't" he hasn't vaulted himself into net positive value for his draft location.
The McKenzie inclusion was solely because Willy literally asked what's a player like Stanley's production/etc look like in terms of value vs McKenzie.
I suppose if you don't believe "development" can be measured in any meaningful way at all and all attempts to do so are futile then I suppose your right, this is all very irrelevant. But that seems very silly to me.
