Zero hockey IQ? Is that a reference to his overly aggressive physical play? He's definitely put himself in some tough situations and missed games as a result. I do believe that's something he can overcome, especially as he moves up levels.
In terms of his offensive hockey IQ, he isn't the type of player who is a step ahead of his opponents but I think it's a little harsh to say he has zero hockey IQ or even that it's an issue. At the OHL level he can be fairly cerebral, displays good timing and understands patterns in game flow. Given how some describe him as a player I think they would be surprised with his ability to slow the game down and the poise he has on the puck. If there's anything that's going to limit his offensive potential it's his lack of deception and at times a heavy touch on the puck. With experience I think he can learn to use his physical attributes to create space rather than relying on deception. I think the criticism of hockey IQ is a little bizarre if you are referencing his offensive potential.
