I think another issue is people talk about needing defenceman that have puck and skating skills so that they can effectively transition from defense to offence and help relieve pressure on themselves and their partner.
The people on the other side of the fence look at this and say "well they can't all be offensive defenseman, they can't all put up points"
When nobody is saying that. They are saying that they want players with enough natural talent that with proper coaching can see the correct passes to make and have the skills to execute them. Or be able to move their feet well enough to open lanes in the other teams defense to exploit.
Being unable to consistently do those sort of things at lower levels likely means the player will likely struggle with them at higher levels. And at that point they become susceptible to turnovers themselves or inclined to always defer puck control to their partner which puts undue pressure in their partner and negates the usefulness of a large part of the ice while trying to transition.
If a players transition abilities are so low that teams don't really have to try to defend them it is unlikely that they can be so effective in other areas that it counters the issues it creates.
Problem is there are different types of players with different rates of maturation.
Any coincidence that the two UDFA "steals", Myers and Zamula, were tall players who matured late physically?
Bigger players tend to take longer to mature (especially in terms of body control) and to develop. Which is why people were patient with Morin.
Obviously Ginning has shown enough to get major PT in the SHL at a very young (17-19) age.
That has nothing to do with draft position, since SHL coaches are paid to win, not develop NHL players.
So he must be doing something they see as valuable, even if he doesn't look pretty in the few snapshots people here are alluding to (who here has watched 20-30 SHL games the last two years other than Appleyard?).
If Ginning doesn't look better at 21-22, then it's time to write him off, right now it's far too early to make definitive conclusions (unless of course you're an amateur expert).
