Yeah, I highly doubt it's out of laziness or anything like that. He just isn't an aggressive offensive forward that naturally has a nose for the goal, similar to Zegras. He's always looking for the best pass or creative play and kind of shoots as a last resort. Unfortunately that extra pass usually ends up on the stick of someone like Killorn and the play dies.
I honestly also think he second guesses himself a lot due to getting smacked around a bit in the NHL. He takes some hard hits for a guy his size and puts himself into dangerous positions, but again that's mainly an experience thing. In the SHL where the rinks are bigger and the play is less physical, he probably wasn't getting physically punished as much for bad positioning.
