I agree. I think the variance in perceptions on this player hinge on whether or not he'll be "one dimensional".
Hockey IQ is probably the hardest attribute to gauge, and I'm certainly not qualified to do it. I would imagine there's an intersection between unconscious and conscious "smartness" that factors in. A conscious awareness of strategy, areas of improvement, knowing how to improve and how to learn ("coachability"), etc.; vs good instincts and habits in the moment-to-moment action - positioning, puck protection, shot selection, knowing when to defer vs when to shoot.
I think there are encouraging signs for both when it comes to Lekkerimaki. I really like his answer to the question of his personal areas of weakness. He was very blunt and honest in saying that he could raise his compete level. I imagine that for players that make scoring effortless; a real "it" factor for taking their game to the next level in the NHL is being able to find a path through speed, physicality, and adversity, and find that extra gear when necessary. It seems that this is the most common concern with Lekkerimaki, so his astute, certain awareness of this is a good sign for me. It conveys an ability to reflect and isolate. Would someone like Jake Virtanen even be capable of that?
There have been some good play-by-play breakdowns in this thread that demonstrate a keen intuitive awareness for creating space, working an effective cycle, creating high % shots, and having the vision to make the pass when it's the better option. For as much as his goalscoring outpaces his assist totals in some statlines, I think his U18 production indicates that he absolutely has the capacity to create and just doesn't have to most of the time because he's the most gifted goalscorer on the team.
