I think he's definitely a Top 6 player, although maybe not now. I also think he's playing exactly the way he's been coached this year: skate hard, forecheck aggressively, work the boards and when in doubt chip or dump the puck. Minimize risk, aim for zone time.
This kid has great tools, and has been a solid-to-prolific scorer at every level. He has some work to in order to learn when to pass, when to shoot, when to crash the net, when to finesse from the boards, when to peel back and protect in order for better options. Ideally, he's a trigger-man doing the work to rush the puck in or dig it out, and more than anything he needs confidence. I don't think it's a coincidence that when the Jets unleash their lowest-risk game, they're not scoring, from anywhere.
