The one thing that stands out with Mynio is how calm he is with the puck on his stick. He's never rattled. I really like his upside, if he puts on some muscle, he's going to be a steal of a pick.
How he's fared with Seattle losing so many top guys, it's a very encouraging sign.
I agree that he is a much more exciting pick than his profile and numbers would suggest.
You make some good points about his calmness on the puck and being relatively small/weak for his draft year. As a late April birth, he is was one of the younger players in the draft and about half a year younger than Brzustewicz for example. He has time/room to grow, which is exciting.
Another encouraging point is his production relative to that of his team. Despite only having played 56 out of Seattle's 61 games so far, he has 48 points on their 166 total goals. That is a 29% goal involvement. In games that Mynio has played, he is at 48/146 = 33% involvement. Seattle's two highest points getters are defencemen (Mynio and Hanzel) and they have no forward producing anywhere close to a point per game after the Sawchyn trade. He just doesn't have much of a supporting cast.
Brzustewicz is at 85 points in 61/62 Rangers games but they have scored way more than Seattle with 270 goals. 31% goal involvement.
Put Mynio on the high-scoring Kitchener team and he would project at 89 points in 62 games given his goal involvement in Seattle.
There is more offensive upside there than his points totals would suggest.
