See that's kind of what I'm laughing at (broadly speaking, not specific to your post).
When Kakko sucks, its because of Quinn.
When he develops, well it's because that's just him returning to form, or getting older, or returning to Finland.
When Miller is in Wisconsin, it's a tire fire and we need to get him out of there.
When he thrives in the NHL thus far, it's because he was developed in Wisconsin. Or because he's a freak athlete who can overcome (wouldn't that also have applied to the tire fire he was supposedly in as well?).y
When Fox signs he is pegged as top four defenseman, ideally more of a second pair type. When he becomes a first pair defenseman, with a trajectory toward elite territory, it's because of the gifts God gave him.
That's without even going into Chytil's progress, or ADA finding his game before blowing it for himself, or how Lindgren went from marginal prospect in the eyes of many to a steady top-four defenseman.
At some point, we don't have agree with everything Quinn does to give him some credit as well. It doesn't have to be one of the other. It can be a mix.
It's not just because kids got older. Because lord knows if they got older, and didn't progress, there would be posters chomping at the bit to point to it as a Quinn failure.
At some point, we spend so much time hopping around on the the things that supposedly suck, that some of the criticisms really do border on parody.
